ObjectiveTo evaluate the efficacy and safety of recombinant human granulocyte-macrophage colony stimulating factor (rhGM-CSF) hydrogel in wound healing in patients with deep partial thickness burn.MethodsThe study was a multicenter, randomized, double-blind, placebo-controlled parallel clinical trial. Three hundred and twenty-one patients (302 cases finally fulfilled the protocol) with deep partial thickness burn were divided into A group (n = 200, with treatment of rhGM-CSF hydrogel, 100 microg/10 g/100 cm2/d), C group (n = 102,with treatment of placebo). Side-effect, systemic condition, wound healing time, wound healing rate, and total effective rate at different time points were observed.ResultsThere were no obvious differences in vital signs, wound secretion, wound edge reaction, blood and urine routine, liver and kidney function between two groups (P > 0.05). No side-effect was observed. The median wound healing time was 17 days in A group, which was obviously shorter than that in C group (20 days, P < 0.01). The mean wound healing rate in A group was 24.5%, 70.5%, 95.3%, 99.6% respectively on 8th, 14th, 20th, 28th day after treatment, which were obviously higher than that in C group (15.1%, 51.4%, 84.6%, 97.1%, respectively, P < 0.01). The total effective rates in A group on 8th, 14th, 20th day after treatment were also higher than that in C group (P < 0.01).ConclusionrhGM-CSF hydrogel can significantly accelerate wound healing in patients with deep partial thickness burn with certain safety.
