  •   Objective   To explore the safety and effectiveness of the application of sevoflurane inhalation sedation and analgesia during dressing changes in children with extensive burns.   Methods   A prospective randomized controlled research was conducted. From March 2020 to January 2023, 216 children with extensive burns who met the inclusion criteria were admitted to the Department of Burns and Plastic Surgery of Kunming Children's Hospital. According to the random number table, the children were divided into sevoflurane group and ibuprofen group, with 103 cases left in sevoflurane group (67 males and 36 females, aged 1 (1, 2) years), and 98 cases left in ibuprofen group (67 males and 31 females, aged 1 (1, 2) years) after the exclusion of several dropped-out children. Children in sevoflurane group received sevoflurane inhalation for sedation and analgesia during dressing changes, while those in ibuprofen group took oral ibuprofen for analgesia before dressing changes. The heart rate, mean arterial pressure (MAP), and percutaneous arterial oxygen saturation (SpO 2) of the children were monitored and recorded at 30 minutes before the start of dressing changes, immediately after debridement, and at 30 minutes after the completion of dressing changes. The face, legs, activity, cry, and consolability scale and Ramsay sedation scale were used to evaluate the pain intensity and degree of sedation, respectively, at 30 minutes before the start of dressing changes, immediately after debridement, and at 30 minutes after the completion of dressing changes. The duration of dressing changes and the total number of dressing changes during hospitalization were recorded. The Houston Pain Outcome Instrument questionnaire was used to assess the satisfaction of the dressing-changing surgeons and a family member of the child with the analgesic effects during the process of dressing change when the children were discharged from the hospital. The occurrence of adverse reactions such as respiratory depression and hypoxemia that occurred during the process of dressing change were monitored and recorded. Data were statistically analyzed with independent sample t test, analysis of variance for repeated measurement, Wilcoxon rank-sum test, chi-square test, and Fisher's exact probability test.   Results   At 30 minutes before the start of dressing changes and 30 minutes after the completion of dressing changes, there were no statistically significant differences in heart rate, MAP, and SpO 2 between children in the two groups ( P>0.05). Immediately after debridement, compared with those in ibuprofen group, the heart rate and MAP of children in sevoflurane group were significantly decreased (with t values of 8.10 and 4.37, respectively, P<0.05), while the SpO 2 was significantly increased ( t=21.77, P<0.05). At 30 minutes before the start of dressing changes and 30 minutes after the completion of dressing changes, there were no statistically significant differences in the score of pain intensity and score of sedation degree between children in the two groups ( P>0.05). Immediately after debridement, compared with that in ibuprofen group, the score of pain intensity of children in sevoflurane group was significantly decreased, while the score of sedation degree was significantly increased (with t values of 42.87 and 72.45, respectively, P<0.05). The duration of dressing changes and the total number of dressing changes during hospitalization of patients in sevoflurane group were (18±3) min and (4.1±1.0) times, respectively, which were both significantly shorter than (26±7) min and less than (6.6±1.4) times in ibuprofen group, respectively (with t values of -4.44 and 14.17, respectively, P<0.05). Upon discharge, the satisfaction scores of dressing-changing surgeons and the family members of children with the analgesic effects during the process of dressing change in sevoflurane group were significantly higher than those in ibuprofen group (with t values of 44.23 and 36.55, respectively, P<0.05). There were no statistically significant differences in the incidence of respiratory depression, hypoxemia, hypotension, coughing, nausea, and vomiting during the process of dressing change between children in the two groups ( P>0.05).   Conclusions   Application of sevoflurane inhalation during dressing changes in children with extensive burns can safely and effectively control pain and sedation, shorten the time for dressing change, with fewer adverse reactions. This method can be used for routine dressing change in pediatric burn wards.
