Abstract:
Nutrition therapy represents one of the most important parts of burn comprehensive treatment and plays a key role in severe burn care, but its curative effect needs to be further improved. With the deepening understanding of body metabolic rules after burn injury, the principle and method of nutrition therapy have been changed. On the one hand, nutrition therapy needs to adapt to the metabolic change post burn. On the other hand, nutrition should regard regulating body metabolism, protecting organ function, and maintaining internal environment stability as the core goals. Hence, some key points such as energy supplement, nutritional opportunity, and nutrition pathway need to be adjusted, in order to improve nutrition efficacy and patient prognosis.

Abstract:
Objective To analyze the relationship between serum lactic acid value and risk of death in patients with extensive burn during shock stage and the related influencing factors. Methods Clinical data of 127 patients (111 males and 16 females) with extensive burn admitted to Institute of Burn Research of the First Affiliated Hospital of Army Medical University from January 2009 to December 2013 and Department of Plastic Surgery and Burns of the Affiliated Hospital of Southwest Medical University from January 2016 to December 2018, who met the admission criteria, were retrospectively analyzed. The patients aged 21 to 62 years, with total burn area more than 50% total body surface area. All patients were treated with antishock therapy after admission. (1) According to the treatment outcome, the patients were divided into survival group (n=98) and death group (n=29). The gender, age, total burn area, partial-thickness burn area, full-thickness burn area, abbreviated burn severity index (ABSI), admission time after injury, number of patients with inhalation injury, number of patients with acute renal failure, and serum lactic acid values on admission and at post admission hour (PAH) 12, 24, 36, and 48 were recorded. (2) According to the optimal positive cut-off value of serum lactic acid 48 hours after admission, the patients were divided into high lactic acid group and normal lactic acid group. Age, gender, total burn area, indexes at PAH 48 including urea nitrogen, creatinine, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total serum bilirubin, alkaline phosphatase (ALP), albumin, white blood cell count, platelet count, lymphocyte count, prothrombin time (PT), hematocrit value, oxygenation index, respiratory index (RI), the alveolar-arterial oxygen partial pressure difference, mean arterial pressure (MAP) at PAH 48, the average urine volume within 48 hours after admission, the total volume of intravenous fluid infusion within 48 hours after admission, the volume of fluid infusion per kilogram of body mass within the first 24 hours after admission, the volume of fluid infusion per one percent of body surface area per kilogram of body mass within the first 24 hours after admission, the volume of urine per kilogram of body mass per hour within the first 24 hours after admission, and the percentage of hospital death were recorded. Data were processed with t test, chi-square test, and Fisher′s exact probability test. Cox regression analysis was used to screen independent risk factors affecting the prognosis of patients. Receiver operating characteristic curve (ROC) of serum lactic acid value at PAH 48 of 127 patients was drawn to predict patients′ death and determine the optimal positive cut-off value. Multivariate logistic regression analysis was used to screen independent risk factors causing increase of serum lactic acid. Results (1) There were significantly statistical differences in total burn area, full-thickness burn area, and ABSI of patients between survival group and death group (t=6.257, 4.476, 5.727, P<0.01), while other indexes between the two groups were close. (2) The serum values of lactic acid of patients in death group on admission and at PAH 12, 24, 36, and 48 were (4.00±0.28), (4.50±0.26), (4.02±0.31), (3.48±0.22), (3.40±0.19) mmol/L, respectively, which were significantly higher than those in survival group [(3.30±0.21), (3.20±0.19), (2.33±0.17), (1.85±0.18), (1.50±0.09) mmol/L, t=14.552, 29.603, 38.133, 40.648, 74.973, P<0.05 or P<0.01]. (3) Cox regression analysis showed that the serum value of lactic acid at PAH 48 was the independent risk factor affecting the prognosis of patients, with risk ratio of 1.853 and 95% confidence interval of 1.342-2.559, P<0.01. (4) The total area under ROC of serum value of lactic acid at PAH 48 to predict death of 127 patients was 0.811, with 95% confidence interval of 0.699-0.924, P<0.01. The optimal positive cut-off value of serum value of lactic acid was 1.75 mmol/L, with sensitivity of 75.0% and specificity of 79.5% for predicting death. (5) There were significantly statistical differences in total burn area, ALT, AST, ALP, PT, total serum bilirubin, total volume of intravenous fluid infusion within 48 hours after admission, volume of fluid infusion per kilogram of body mass within the first 24 hours after admission, and percentage of hospital deaths of patients between high lactic acid group (n=34) and normal lactic acid group (n=93), t=3.592, 6.797, 10.367, 2.089, 2.880, 4.517, 2.984, 4.044, χ2=58.498, P<0.05 or P<0.01, while other indexes were close between the two groups. (6) Multivariate logistic regression analysis showed that AST and total serum bilirubin were independent risk factors for increase of serum lactic acid, with odds ratios of 1.021 and 1.064 and 95% confidence intervals of 1.001-1.040 and 1.001-1.132, P<0.05. Conclusions Serum value of lactic acid at PAH 48 can independently predict the death of patients with extensive burns. Liver injury is an important risk factor causing hyperlacticemia during burn shock stage. Widespread increase of vascular permeability and large amount of fluid resuscitation are the core factors leading to aggravation of abdominal organ injury.

Abstract:
Objective To explore the effects of insulin therapy on skeletal muscle wasting (SMW) in severely scalded rats and its related mechanism. Methods Totally 48 male Wistar rats aged 7-8 weeks were divided into simple scald (SS) group and insulin therapy (IT) group according to the random number table, with 24 rats in each group. After weighing the body mass and measuring the blood glycemic level of the tail end with a glucometer, the rats in the two groups were immersed in hot water at 94 ℃ for 12 seconds to make a full-thickness dorsal scald model involving 30% total body surface area. Rats in group IT were subcutaneously injected with 1 U/kg insulin glargine at 8: 00 a day from post injury day (PID) 1 to 7, whilst rats in group SS were given the same amount of normal saline. Rats in the two groups were given 10 mL/kg enteral nutritional emulsion by intragastric infusion at 8: 00 (after insulin administration), 13: 00, and 18: 00 a day respectively from PID 1 to 7. The blood glycemic levels of tail end of rats in the two groups were measured by glucometer before insulin administration on PID 1-4, 6, and 7 and on every morning of PID 8, 9, 11, 12, and 14. The body mass of rats in the two groups on PID 14 without any treatment was weighed. Eight rats from each group were collected respectively on PID 4, 7, and 14 to harvest tibialis anterior muscle (TAM) samples. The mass of TAM on PID 14 was weighed. The ultrastructural changes of TAM myocytes on PID 7 were observed with transmission electron microscope. The apoptotic rates of TAM myocytes on PID 4, 7, and 14 were assessed by the assay of terminal deoxynucleotidyl transferase-mediated deoxyuridinetriphate-biotin nick end labeling, the expressions of cysteine-aspartic protease-3 (caspase-3) of TAM on PID 4, 7, and 14 were detected with immunohistochemistry, and protein expressions of endoplasmic reticulum (ER) stress (ERS) associated proteins glucose-regulated protein 78 (GRP78), CCAAT/enhancer binding protein-homologous protein (CHOP), and activated caspase-12 of TAM on PID 4, 7, and 14 were detected with Western blotting. Data were processed with completely random design t test, analysis of variance for repeated measurement, analysis of variance for factorial design, t test, and Bonferroni correction. Results The blood glycemic level and body mass of rats in the two groups before injury were similar (t=0.204, 0.405, P>0.05). There were no statistically significant differences in blood glycemic levels of rats between the two groups on PID 1, 6, 9, 11, 12, and 14 (t=0.229, 3.339, 1.610, 0.178, 0.181, 0.079, P>0.05). Compared with those of group SS, blood glycemic levels of rats in group IT were significantly lower on PID 2, 3, 4, 7, and 8 (t=7.245, 4.165, 4.609, 4.018, 3.995, P<0.05 or P<0.01). On PID 14, the body mass and TAM mass of rats in group IT were (271±19) g and (0.47±0.05) g respectively, both obviously higher than (254±12) g and (0.43±0.04) g of group SS (t=2.159, 2.375, P<0.05). On PID 7, nuclear pyknosis and deformation, chromosome misdistribution, and ER swelling in TAM myocytes of rats in group SS were observed; the apoptotic alterations and ER swelling of TAM myocytes were alleviated in rats of group IT as compared with those of group SS. The apoptotic rates of TAM myocytes of rats in group IT were obviously lower than those of group SS on PID 4, 7, and 14 (t=4.262, 9.153, 9.799, P<0.01). The expressions of caspase-3 in TAM of rats in group IT were obviously lower than those of group SS on PID 7 and 14 (t=10.429, 7.617, P<0.01). Compared with those of group SS, the protein expressions of GRP78 were obviously increased on PID 4 and 14 (t=4.172, 4.437, P<0.05), the protein expressions of activated caspase-12 were obviously decreased on PID 7 and 14 (t=11.049, 11.181, P<0.01), and the protein expressions of CHOP were obviously decreased on PID 4, 7, and 14 (t=13.837, 9.572, 6.930, P<0.01) in TAM of rats in group IT. Conclusions Insulin therapy may reduce skeletal muscle myocytes apoptosis and SMW by alleviating ERS in rats with severe scald.

Abstract:
Objective To observe how glutamine affect the skeletal muscle membrane repair in severely burned mice through promoting the mitsugumin 53 (MG53) dimerization in skeletal muscle and to explore its functional mechanism. Methods (1) Animal experiments. A total of 179 BALB/c male mice aged 6 to 8 weeks were divided into sham injury group (n=43), burn group (n=73) and burn+ glutamine group (n=63) according to the random number table (the same grouping method below). Mice in sham injury group were sham injured on the back, and mice in burn group and burn+ glutamine group were inflicted with 30% total body surface area full-thickness scald (hereinafter referred to as burn) on the back. Mice in burn+ glutamine group were intragastrically administered with glutamine (1 mg/kg), and the other two groups were given the same amount of amino acid solution once per day for 14 days. On post burn hour 12, 10 mice from burn group were taken for preparation of burn serum, which is used in the following cell experiments. Blood samples were collected from the hearts to prepare serum from 10 mice in sham injury group immediately after burn and from 10 mice in burn group and burn+ glutamine group on post burn day (PBD) 5, 10, and 14, respectively. And then the whole gastrocnemius muscle was harvested after the mice were sacrificed. On PBD 10, the whole flexor brevis digitorum was harvested from 6 mice in the 3 groups respectively after the mice were sacrificed. On PBD 5, 10, and 14, the whole gastrocnemius muscle tissue was harvested from another 9 mice in the 3 groups respectively after the mice were sacrificed. The mass of the whole gastrocnemius muscle of mice was weighed. The total protein content of gastrocnemius muscle of mice was detected by coomassie brilliant blue method. The repair function of myolemma of flexor brevis digitorum of mice was detected by two-photon laser fiber membrane perforating. The serum content of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) of mice was determined with radioimmunoassay. The expressions of MG53 dimer and monomer in gastrocnemius of mice were determined with non-reductive electrophoresis-Western blotting. The protein expressions of endoplasmic reticulum stress sign proteins CCAAT/enhancer binding protein homologous protein (CHOP) and glucose-regulated protein 78 (GRP78) in gastrocnemius of mice were determined with Western blotting. (2) Cell experiments. Mice skeletal muscle precursor cells C2C12 were cultured in vitro, and cells of the second passage were selected for the experiments. The cells were divided into normal control group, burn serum group, and burn serum+ glutamine group, with 3 dishes in each group and 1×103 cells in each dish. Cells in normal control group were cultured with 1 mL Dulbecco′s modified Eagle medium (DMEM) with fetal bovine serum of volume fraction 10%, cells in burn serum group were cultured with 1 mL DMEM with burn serum of volume fraction 10%, and cells in burn serum+ glutamine group were cultured with 1 mL DMEM with burn serum of volume fraction 10% and 4 μL glutamine with a final molar concentration of 8 mmol/L. After 24 hours of culturing, the repair function of myocyte membrane after differentiation of skeletal muscle precursor cells in mice was detected with the same method before. Another cells were grouped and cultured as before, with 3 wells in each group and 1×105 cells in each well. After 24 hours of culturing, the expressions of MG53 dimer and monomer and endoplasmic reticulum stress marker proteins in the cells were detected as before. Data were processed with analysis of variance of factorial design, one-way analysis of variance, least significant difference t test, and Student Newman Keuls test. Results Animal experiments. (1) Compared with those in sham injury group, the mass and total protein content of gastrocnemius muscle of mice in burn group were significantly decreased on PBD 5, 10, and 14 (P<0.05). Compared with those in burn group, the mass and total protein content of gastrocnemius muscle of mice in burn+ glutamine group were significantly increased on PBD 5, 10, and 14 (P<0.05). (2) Compared with that in sham injury group (0.9±0.4), the fluorescence intensity of FM1-43 in myofiber of mice in burn group (7.8±0.4) was significantly increased on PBD 10 (t=7.75, P<0.05). Compared with that in burn group, the fluorescence intensity of FM1-43 in myofiber of mice in burn+ glutamine group (4.0±0.4) was significantly decreased on PBD 10 (t=-4.31, P<0.05). (3) Compared with that in sham injury group, the serum content of TNF-α and IL-6 of mice in burn group was significantly increased on PBD 5, 10, and 14 (P<0.05). Compared with that in burn group, the serum content of TNF-α and IL-6 of mice in burn+ glutamine group was significantly decreased on PBD 5, 10, and 14 (P<0.05). (4) Compared with 56.97±2.82, 44.89±4.72, 42.46±1.06, 14.26±0.99, 62.36±2.74, and 29.45±0.84 in sham injury group, the expressions of MG53 dimer and monomer in gastrocnemius of mice were significantly decreased in burn group on PBD 5, 10, and 14 (6.16±0.25, 26.09±1.22, 28.86±1.53, 5.63±0.25, 26.74±0.79, 4.41±0.52, P<0.05). Compared with those in burn group, the expression of MG53 dimer of gastrocnemius of mice in burn+ glutamine group was significantly increased on PBD 10 and 14 (36.79±1.44, 43.96±1.62), and the expression of MG53 monomer of gastrocnemius muscle of mice in burn+ glutamine group was significantly increased on PBD 14 (13.16±2.17, P<0.05). Compared with those in sham injury group, the protein expressions of CHOP and GRP78 in gastrocnemius muscle of mice in burn group were significantly elevated on PBD 5, 10, and 14 (P<0.05). Compared with those in burn group, the protein expressions of CHOP and GRP78 in gastrocnemius of mice in burn+ glutamine group were significantly reduced on PBD 5, 10 (P<0.05). Cell experiments. (1) Compared with that in normal control group (1.76±0.25), the fluorescence intensity of FM1-43 in cells in burn serum group (9.46±1.22) was significantly increased after 24 hours of culturing (t=12.28, P<0.05). Compared with that in burn serum group, the fluorescence intensity of FM1-43 in cells in burn serum+ glutamine group (4.71±0.45) was significantly decreased after 24 hours of culturing (t=-7.59, P<0.05). (2) The expressions of MG53 monomer of cells were similar in normal control group, burn serum group, and burn+ glutamine group after 24 hours of culturing (P>0.05). Compared with 58.5±1.8 in normal control group, the expression of MG53 dimer of cells in burn serum group was significantly decreased after 24 hours of culturing (14.1±1.4, P<0.05). Compared with that in burn serum group, the expression of MG53 dimer of cells in burn serum+ glutamine group was significantly increased after 24 hours of culturing (30.9±0.6, P<0.05). Compared with those in normal control group, the protein expressions of CHOP and GRP78 of cells were significantly elevated in burn serum group after 24 hours of culturing (P<0.05). Compared with those in burn serum group, the protein expressions of CHOP and GRP78 of cells were significantly reduced in burn serum+ glutamine group after 24 hours of culturing (P<0.05). Conclusions Glutamine can promote MG53 dimerization by alleviating endoplasmic reticulum stress in severely burned mice. Thus it can accelerate skeletal muscle membrane repair, reduce the local inflammatory reaction of skeletal muscle and consumption of skeletal muscle.

2019, 35(5): 351-355. doi: 10.3760/cma.j.issn.1009-2587.2019.05.005
Abstract
Abstract:
Objective To investigate the early diagnosis method of pulmonary embolism in patients with skin and soft tissue defects after trauma. Methods From January 2011 to July 2014, 5 patients with skin and soft tissue defects and pulmonary embolism after trauma were admitted to Department of Plastic Surgery and Burns of the Affiliated Drum Tower Hospital of Nanjing University Medical School, including 4 males and 1 female, aged 26-68 years. The medical records of the 5 patients were retrospectively analyzed. Hierarchical screening of patients with suspected pulmonary embolism was performed after admission for 4-45 days. Computed tomography pulmonary angiography (CTPA) was performed immediately in 2 patients who had hemodynamic disorder and were able to tolerate CTPA, and pulmonary embolism was confirmed. Clinical risk assessment was conducted for the other 3 patients who had no obvious hemodynamic disorder and only had clinical manifestations of pulmonary embolism such as chest tightness and dyspnea. Among the 3 patients, two of them were assessed as high risk possibility by clinical risk assessment and diagnosed with pulmonary embolism by CTPA immediately. The other one patient′s clinical risk assessment was moderate risk possibility, but D-dimer was positive, and the patient was diagnosed with pulmonary embolism by CTPA immediately. Wound exudation of all patients was collected within 1 week after admission for microbial culture, and wound debridement and skin grafting were performed according to the wound condition. The color Doppler ultrasonography of blood vessel on lower extremity was performed to determine deep venous thrombosis of lower extremity after appearance of symptoms of pulmonary embolism. The patient was immediately given urokinase or recombinant tissue plasminogen activator by intravenous infusion for thrombolysis after definite diagnosis of pulmonary embolism. The activated partial thromboplastin time (APTT) was monitored after treatment, and standardized anticoagulation began when APTT was equal to or lower than 70 seconds. The treatment results of patients, D-dimer measurement value, bed time before definite diagnosis of pulmonary embolism, number of patients underwent wound debridement during hospitalization, definite diagnosis time of pulmonary embolism after wound debridement, and number of patients with deep venous thrombosis of lower extremity and wound infection were recorded. Results Wounds with skin and soft tissue defects of all patients were completely healed, all skin grafts survived well, pulmonary embolism recovered well after timely treatment, and the trunk and branches of involved pulmonary artery recovered blood supply. The course of disease ranged from 1 month to 3 months. The measurement value of D-dimer was 2.4-31.7 mg/L, and the measurement values of D-dimer of 4 patients were equal to or higher than 5.0 mg/L. The bed time before definite diagnosis of pulmonary embolism was 4-46 days, with an average of 23.2 days. Four patients underwent wound debridement during hospitalization. The definite diagnosis time of pulmonary embolism after the wound debridement was 14-40 days, with an average of 20.5 days. Four patients were diagnosed with deep venous thrombosis of lower extremity. All patients had wound infection, and the bacteria causing wound infection included Pseudomonas aeruginosa of 2 cases, Staphylococcus aureus of 2 cases, and Enterococcus faecalis of 1 case. Conclusions In the diagnosis process of pulmonary embolism in patients with skin and soft tissue defects after trauma, D-dimer positive, long-term bed rest, experiencing operation during hospitalization, and with deep vein thrombosis and wound infection can be regarded as the key points for diagnosis. When a patient has clinical symptoms of pulmonary embolism and the above conditions, the clinician should promptly perform hierarchical screening, select the corresponding examination to confirm pulmonary embolism, and immediately perform thrombolysis for the patient with pulmonary embolism according to the patient′s tolerance, thereby improving patient survival rate.

Abstract:
Objective To explore the effect of the perforator flap of the proper digital artery on the ulnar or radial side of the finger in the treatment of webbed scar contracture of the same finger in child. Methods From January 2012 to January 2016, 26 children who were treated with dressing change after burn of finger and then had webbed scar contracture along with growth and development were hospitalized in our unit, involving a total of 50 fingers. There were 14 males and 12 females among the children aged from 2 to 14 years. After the scar was dissected and released, the wound area ranged from 1.6 cm×1.0 cm to 5.0 cm×2.6 cm. The perforator flap of the proper digital artery of the ulnar or radial side of the same finger was used to repair the wound. The flap area ranged from 1.8 cm×1.0 cm to 4.6 cm×1.8 cm. The donor sites were sutured directly. The residual wounds in donor and recipient sites were repaired by full-thickness skin graft collected from inguinal area/adjacent area or adjacent perforator flap. The postoperative development and function of the fingers were followed up and observed. The range of motion of the fingers was evaluated according to the Chinese Medical Association Hand Surgery Society′s upper limb functional evaluation trial standard, the Kantor Scar Cosmesis Assessment and Rating Scale was used to score the scar of finger, and the latest data were recorded. Results The flaps and skin grafts survived successfully after operation. The patients were followed up for 6 to 24 months. The perforator flaps of the proper digital artery on the ulnar or radial side of the finger survived well at the latest follow-up, with good color and texture and a two-point discrimination distance of 9 to 12 mm. There was no contracture of the fingers, a little pigmentation in the skin graft area, no flexion deformity of the fingers, no lateral bending of the fingers to the flap-harvesting side, and no scar contracture at the webs of the fingers. Compared with that of healthy side, the development of finger was not obviously abnormal. The range of motion of the fingers was excellent in 38 fingers and good in 12 fingers, and the scar score of the fingers was 2-3 points in 31 fingers, 4-7 points in 15 fingers, and 8-10 points in 4 fingers. Conclusions The efficacy of perforator flap of the proper digital artery of the ulnar or radial side of finger in the treatment of the webbed scar contracture of the same finger in child is reliable, with high postoperative survival rate of the flap, better color and texture, and fewer complications, which can avoid the risk of re-contracture of the finger in a short period after operation, and does not affect the growth and development of the finger.

Abstract:
Objective To explore the repair methods and effects of the complex wounds on hands after burns or trauma. Methods From January 2008 to December 2017, 45 patients (28 males and 17 females, aging 8 to 58 years) with severe hand injuries after burns or trauma combined with deep tissue exposure were admitted to our hospital. Two patients had whole-fingers degloving injuries, 27 patients had dorsal hand injuries, and 16 patients had palmar injuries. After debridement, the area of soft tissue defects was 7 cm×6 cm to 19 cm×12 cm combined with 0.5 cm×0.4 cm to 10.0 cm×4.0 cm of single deep tissue exposure. Different repairing methods were adopted according to the area and location of deep tissue exposure. Five patients with small area exposure were treated with artificial dermis+ vacuum sealing drainage (VSD)+ autogenous skin grafting. Thirty-eight patients with unilateral large area exposure on palm or dorsum were treated with segmented ligation of abdominal thin flaps (with area of 8 cm×7 cm to 15 cm×9 cm). Two patients with bilateral large area exposure in dorsal and palmar hands were treated with modified abdominal bag-shaped delayed thin flaps (with area of 12 cm×5 cm to 12 cm×9 cm and 12 cm×6 cm to 14 cm×9 cm). The donor sites were directly sutured or repaired with intermediate split-thickness skin or adjacent flap. The survival of grafts and flaps was observed, number of operations, wound healing time, and follow-up were recorded. Results (1) Among the patients receiving artificial dermis+ VSD+ autogenous skin grafting, the wounds of 3 patients were healed after 2 operations, and 2 patients had artificial dermis infection and lysis, and tendon necrosis, which were healed after 3 operations. The wound healing time of 5 patients was 14 to 33 days post injury. During the follow-up of 3 months, the affected hands were in good shape with soft texture and fewer scars, and functional evaluation of hand was good in 3 cases and modest in 2 cases. (2) The patients receiving segmented ligation of abdominal thin flaps all underwent 2 operations without flap necrosis. The wound healing time was 2 to 3 weeks post injury. Thirty-five patients underwent one to six-years′ follow-up, which showed that the flaps were in good shape and color with soft texture, and the functional evaluation of hand was excellent in 25 cases, good in 7 cases, and modest in 3 cases. Three patients were lost to follow-up. (3) In the 2 patients receiving modified abdominal bag-shaped delayed thin flaps, all flaps survived after 5 operations, the wounds were healed on post injury day 22 and 24 respectively, the shape and texture of the affected hands was good with no bloated appearance after separating fingers and revision. During the follow-up of 2 years, the functional evaluation of hand was good in 2 cases. Conclusions For the complex wounds on hands after burns or trauma, if the area of deep tissue exposure is small, artificial dermis+ VSD+ autogenous skin grafting should be adopted, which has good effects. If the area of unilateral deep tissue exposure is large, segmented ligation of abdominal thin flap should be adopted; if the area of bilateral deep tissue exposure is large, modified abdominal bag-shaped delayed thin flap should be adopted. These methods can reduce the number of operations, shorten wound healing time, and obtain good shape and function of hands.

Abstract:
Objective To explore the clinical effects of superior gluteal artery perforator island flap in repair of sacral pressure ulcer. Methods From May 2012 to May 2017, 20 patients with sacral pressure ulcers (14 males and 6 females, aged 27 to 67 years) were admitted to our department. According to the consensus staging system of National Pressure Ulcer Advisory Panel in 2016, 6 cases were in 3 stages, 14 cases were in 4 stages, with the area of pressure ulcers ranging from 5.0 cm×4.0 cm to 10.0 cm×8.0 cm. After debridement and vacuum sealing drainage, the superior gluteal artery perforator island flaps were used to repair the pressure wounds, with the area of flaps ranging from 6 cm×5 cm to 13 cm×8 cm. The donor sites were sutured directly. The survival of flaps after operation, the healing of wounds, and the follow-up of patients were observed. Results After surgery, flaps of 20 patients survived well without reoperation. The length of hospital stay of patients was 20 to 40 days, with an average of 25 days. Eighteen patients were followed up for 6 to 24 months, with an average of 12.2 months. The flaps were in good shape and elastic recovery. There were no complications such as seroma or hematoma in the donor sites. Both the patients and family members expressed satisfaction with the shape and texture of the flap and shape of hip. Conclusions The superior gluteal artery perforator island flap is reliable in blood supply and easy to rotate. The flap can carry a little muscle to increase the anti-infective ability. Moreover, the donor site can be directly sutured with slight damage. Thus, it is one of the good methods for repairing sacral pressure ulcers.

Abstract:
Objective To summarize the physical and psychosocial problems of burned children aged 0 to 5 years so as to explore their demands of care after discharge. Methods Databases including Embase, PubMed, PsycARTICLES, and CINAHL Complete were searched using key words " child*, infant*, toddler, preschool, kid, baby, junior, burn, scald, empyrosis, nursing, care" , and Chinese Journals Full-text Database, China Biology Medicine disc, and VIP Database were searched using key words in Chinese version "小儿,儿童,幼儿,学龄前,婴儿,新生儿,烧伤,烫伤,照护" to obtain the articles about physical and psychosocial health-related problems of burned children aged 0 to 5 years after discharge from the establishment of each database to February 2018. After screening of extracted articles, the physical and psychosocial problems of burned children aged 0 to 5 years after discharge and psychosocial problems of their caregivers were summarized. Results (1) A total of 3 880 articles were obtained, after screening layer by layer, 9 English articles were finally included, including 4 prospective observational studies, 3 cross-sectional studies, 1 cohort study, and 1 case-control study, with 1 high-quality literature and 8 medium-quality literatures. (2) After discharge, burned children aged 0 to 5 years mainly had physical problems such as pain, itching, fine motor developmental disorders, and gross motor developmental disorders. They had psychosocial problems such as negative emotional behavior, delayed language development, affected game interaction, post-traumatic stress disorder (PTSD), and disrupted family life. The caregivers had psychosocial problems such as worrying about the appearance and the future of children, dissatisfaction with the current status of children, anxiety and depression, pain, and PTSD. The influencing factors of the above health problems were post-discharge time, post-injury time, total burn area, and burn site, etc. There were 12 kinds of measuring tools used in this group to evaluate the health problems of burned children and psychosocial problems of their caregivers. Only the burn outcomes questionnaire for children aged 0 to 5 years was developed for burned children aged 0 to 5 years. Conclusions After discharge, burned children aged 0 to 5 years still face many physical and psychosocial problems, which are influenced by factors such as post-discharge time, post-injury time, total burn area and burn site, which suggests that there are certain care needs for them. Appropriate tools for evaluating the health problems of burned children aged 0 to 5 years should be developed.

Abstract:
Objective To investigate the current status of uncertainty in illness and caregiving burden in family members of patients with chronic wounds, and to analyze the relationship between them. Methods A total of 180 patients with chronic wounds admitted to the Department of Emergency of our hospital from October 2017 to March 2018, conforming to the study criteria, were selected by adopting the convenience sampling method. Then one family member who took care of the patients for the longest time and conformed to the study criteria were included in this cross-sectional survey. General Information Questionnaire made by the authors was conducted to investigate the demographic data and wounds of patients, and demographic data of family members. Chinese version of Parent Perception of Uncertainty Scale-Family Member (PPUS-FM) and Caregiver Burden Inventory (CBI) were used to investigate the uncertainty in illness and caregiving burden. Data were processed with multiple linear regression analysis and partial correlation analysis. Results The effective recovery rate of questionnaire was 91.7% (165/180). (1) The ages of patients were (71±17) years. Among them, there were 89 males and 76 females. The course of chronic wounds was 0.5 to 120.0 months. The wounds were mainly primary occurrence (86.1%, 142 patients), and the main type of wound was pressure ulcer (43.6%, 72 patients). Fifty-seven patients (34.5%) had wound infection. The ages of family members were (56±13) years, and 61.8% (102 people) of them were female. Their daily time of taking care of patients was (10±8) h. (2) The total scores of PPUS-FM of family members were 33 to 125 (88±17) points, mainly in medium level, in which the item score of unpredictability dimension was the highest. (3) The total scores of CBI of family members were 7 to 79 (43±14) points, in which the item score of time-dependence burden dimension was the highest. (4) Uncertainty in PPUS-FM could independently influence 10% of the total variation of caregiving burden in family members of patients (t=3.18, P<0.01). (5) The total scores of PPUS-FM of family members were in significantly positive correlation with the total scores of CBI and scores of physical burden, emotional burden, and social burden, respectively (r=0.33, 0.32, 0.25, 0.36, P<0.05 or P<0.01), while there was no obvious correlation between total scores of PPUS-FM of family members and time-dependence burden/developmental burden (r=0.14, 0.16, P>0.05). Conclusion There is positive correlation between uncertainty in illness and caregiving burden.

Abstract:
Objective To explore the application experience of integrated nursing mode in the treatment of extremely severe burn patients in August 2nd Kunshan factory aluminum dust explosion accident. Methods On August 2nd, 2014, 35 extremely severe burn patients involved in the August 2nd Kunshan factory aluminum dust explosion accident were admitted to Wuxi Third People′s Hospital, including 18 males and 17 females, aged 21-50 years. According to the characteristics of the wounded, the situation of the nursing staff, and the characteristics of the nursing work, the integrated nursing mode was constructed and implemented to improve overall nursing quality. The standardized management measures such as cluster management of facilities and equipments in wards, improving and unifying nursing system, standardized training, drawing up " Nurses Compulsory Reading" , optimizing nursing shift handover and so on were taken. Professional quality control groups such as continuous renal replacement therapy (CRRT) group, static therapy group, airway group, and burn group were established, and standardized writing nursing group, wound nursing group, psychological nursing group, and enteral nutrition nursing group were set up under burn group. The treatment outcomes of patients and effects of nursing management, nursing methods, and specialty nursing were recorded. Results Twenty-seven patients survived the shock period, infection period, and recovery period smoothly. The success rate of rescue was 77.14%. During the treatment, the ward was in good order. The implementation rate of disinfection and isolation system, the completion rate of shift handover, the standard rate of intravenous therapy, the implementation rate of bed head elevation, the correct rate of posture placement, and the success rate of CRRT were all 100%. Successful turn over of rotating bed without interruption of CRRT for 24 hours was implemented in two patients. In many cases, the single filter for hemodialysis continuously run for more than 72 hours. The airway mucosa of patients healed around 20 days after injury. No adverse nursing events such as tracheal cannula detachment/blockage, respiratory distress, atelectasis, lung consolidation, aspiration by mistake, rotating bed rollover, ear chondritis, nasal septal pressure ulcer, vacuum sealing drainage (VSD) catheter blockage, VSD dressing leakage, severe abdominal distension/diarrhea, non-planned extubation/blockage of various intravenous treatment catheters implanted into deep veins and arteries were observed. Conclusions The integrated nursing mode significantly optimizes the nursing work process in the treatment of extremely severe mass burns, clarifies the duties of nursing staff, and improves the quality of nursing. This mode is worthy of taking reference by other burn treatment units.

Abstract:
Objective To explore the application value of color Doppler ultrasound-guided percutaneous dilational tracheostomy with dilatation forceps in patients with head and neck burns complicated with upper respiratory tract obstruction. Methods From July 2013 to June 2018, 17 patients with head and neck burns complicated with upper respiratory tract obstruction, including 15 males and 2 females, aged 19-63 years, were hospitalized in our unit and treated with color Doppler ultrasound-guided percutaneous dilational tracheostomy with dilatation forceps. Before operation, the trachea was examined by color Doppler ultrasonography to specify condition of trachea and peribronchial tissues and organs for comprehensive assessment, so as to confirm optimal incision site of puncture and pathways as well as specify distance from anterior cervical skin to intima of anterior tracheal wall. Then, under real-time guidance of color Doppler ultrasound, percutaneous dilational tracheostomy with dilatation forceps was performed. The position, shape, inner diameter, and intraluminal abnormalities of trachea of patients before operation, abnormal location of peribronchial vessels and thyroid, distance from anterior cervical skin to intima of anterior tracheal wall, success rate of puncture, surgical time (from skin disinfection to successful catheterization), success rate of catheterization, intraoperative blood loss, heart rate, blood pressure, respiration, percutaneous oxygen saturation, and presence or absence of complications such as vascular/thyroid injury, emphysema, pneumothorax, suffocation, postoperative hemorrhea, wound infection after operation were observed and detected. Results (1)Preoperative color Doppler ultrasonography showed that the trachea of one patient deviated from the anterior median line of neck 13 mm to the right; 17 patients had edema of different degrees in the cervical soft tissue and more secretions in the trachea; 3 patients had the trachea changed from round to oval with reduced anteroposterior diameter; 1 patient had a small artery obstruction at the conventional puncture point; 2 patients had the trachea covered by the congestive and swollen isthmus of the thyroid between the first and the third tracheal cartilage rings; 16 patients had a distance from anterior cervical skin to anterior tracheal wall intima of 17-33 mm, and 1 patient had a distance from anterior cervical skin to anterior tracheal wall intima of 47 mm. (2) Puncture for 17 patients was successful at one time, and success rate of puncture was 100%. The operation time was 5-11 min, with an average of 7 min, and the success rate of catheterization was 100%. (3) Intraoperative blood loss of patients was less, all not exceeding 8 mL. Intraoperative percutaneous oxygen saturation was maintained between 0.90 and 0.99. The heart rate, blood pressure, and respiration were stable. (4) No complications such as vascular/thyroid injury, emphysema, pneumothorax, suffocation, postoperative massive hemorrhage, or wound infection occurred in any patient. Conclusions Applying color Doppler ultrasound-guided percutaneous dilational tracheostomy with dilatation forceps in patients with head and neck burns combined with upper respiratory tract obstruction can not only open up the airway quickly and effectively, but also reduce the complications related to the operation. It is expected to improve the success rate of rescue and improve the prognosis, making it of good application value.

Abstract:
Objective To explore the clinical effect of double blood supply composite tissue flap with peroneal artery perforator and sural nerve nutrient vessel carrying gastrocnemius muscle in repairing lacunar skin and soft tissue defect of ankle. Methods From September 2015 to September 2017, 10 patients with lacunar skin and soft tissue defects of ankle were hospitalized in our unit, including 7 males and 3 females, aged 17-62 years, 8 traffic accident injuries and 2 heavy body pressure injuries. After debridement, the wound area ranged from 7 cm×4 cm to 15 cm×9 cm, and the lacunar area ranged from 3.0 cm×2.0 cm×1.0 cm to 7.0 cm×4.0 cm×2.0 cm. The defect was repaired with island composite tissue flap with peroneal artery perforator and sural nerve nutrient vessel and partial gastrocnemius muscle at stage Ⅰ. The area of flaps ranged from 8 cm×5 cm to 16 cm×10 cm, and the area of gastrocnemius muscle flaps ranged from 4 cm×3 cm to 8 cm×5 cm. The donor site was repaired with ipsilateral thigh intermediate split-thickness skin graft or sutured directly. The location of vascular pedicle, survival of tissue flap, follow-up, and occurrence of complications were recorded. Results The vascular pedicle of this group of cases was located 5-15 cm above the lateral malleolus. The tissue flaps of 10 patients survived completely after operation at stage Ⅰ. Follow-up for 1-12 months showed that the area repaired with tissue flaps had good color, blood supply, and texture, without ulceration, and recovered different degrees of pain sensation and deep tactile sensation, and no short-term or long-term complications occurred. Conclusions The double blood supply composite tissue flap with peroneal artery perforator and sural nerve nutrient vessel carrying gastrocnemius muscle has good blood supply, which can effectively fill the invalid space in repairing lacunar skin and soft tissue defect of ankle, with good effect after operation, and it is worthy of clinical application.

Abstract:
On September 7th, 2017, one female patient, aged 48 years with deep partial-thickness flame burn on face, upper limbs, trunk, and lower limbs of 40% total body surface area was admitted to the First People′s Hospital of Foshan City. After admission, active fluid replacement, anti-infection, nutritional support, and other treatments were performed. After debridement and skin grafting for 3 times and blood transfusion for 2 times, the patient recovered well. On the 20th day post admission, sudden heartbeat and respiratory arrest happened, and the patient died after ineffective rescue. Autopsy showed that thrombus formed in right internal jugular vein and deep veins of lower extremities, and vascular lumina of the bilateral pulmonary artery. The direct cause of death was acute pulmonary thromboembolism, but whether the embolus originated from deep vein of lower extremity or right internal jugular vein was not clear. This case suggests that clinician should not only pay attention to the prevention of deep venous thrombosis of lower extremities of burn patients, but also the possibility of internal jugular vein thrombosis, especially for patients with internal jugular vein access.
