Objective To observe the clinical effects of recombinant human growth hormone (rhGH) on children with severe burn.
Methods Clinical data of 94 children with severe burn, hospitalized in our burn unit from April 2012 to December 2016, conforming to the study criteria, were retrospectively analyzed. According to the use of rhGH, children were divided into rhGH group (
n=50) and control group (
n=44). Children in control group received conventional treatment, while children in rhGH group received both conventional and rhGH treatment. The rhGH treatment was started 3 to 5 days post injury in dosage of 0.2-0.4 U·kg
-1·d
-1, by way of subcutaneous injection, and the course of treatment was (11±5) d. The plasma albumin and prealbumin levels, heart rate, alanine aminotransferase (ALT), and serum creatinine level in 2 weeks post injury, times of skin grafting operation, hospitalization time, total hospitalization treatment cost, and sepsis and death of children were compared between the 2 groups. Data were processed with independent sample
t test, Mann-Whitney
U test, and Fisher′s exact test.
Results (1) In 2 weeks post injury, the plasma albumin level [(36±4) g/L] and prealbumin level [(94±34) g/L] of children in rhGH group were significantly higher than those in control group [(33±4) and (73±20) g/L,
t=3.666, 3.401,
P<0.05]. (2) In 2 weeks post injury, the heart rate of children in rhGH group was (123±11) times per minute, which was slower than (130±14) times per minute of children in control group (
t=2.839,
P<0.05). There was no significant difference in ALT level of children between the 2 groups (
Z=0.868,
P>0.05). The blood creatinine levels of children in the 2 groups were within normal range. (3) The times of skin grafting operation of children in rhGH group was 0.3±0.5, which was significantly less than 0.5±0.6 in control group (
Z=2.234,
P<0.05). The hospitalization time of children in rhGH group was (22±8) days, which was shorter than (28±10) days in control group (
t=2.837,
P<0.05). The total hospitalization treatment cost of children in rhGH group was (41±15) thousand yuan, which was significantly less than (53±25) thousand yuan in control group (
t=2.878,
P<0.05). (4) There were 2 cases of sepsis in control group and 1 case of sepsis in rhGH group, with no significant difference between the 2 groups (
P>0.05). No children died in the 2 groups.
Conclusions rhGH treatment of children with severe burn can correct post-injury hypoproteinemia, improve cardiac function, reduce the times of skin grafting operation and hospitalization treatment cost, shorten hospitalization time, with no significant effect on kidney and liver function, sepsis, and death.
