RESUMO
Objective To study the mechanism of glutamine dipeptide on wound healing after operations on bums. Methods Totally, 30 burned patients were randomly divided into study group and control group (15 cases in each group). All patients received parental nutrition support after operation. Study group patients were supplemented with glutamine dipeptide at a dose of 0. 5 g · kg±1 · d±1. The plasma free hydroxyproline level was measured by a standard amino acid analyzer 1 day before operation and 7 days after operation and the wound healing time was recor± ded. Results The plasma free hydroxyproline levels of both groups were higher than the normal values before opera± tion but without significant difference [control group: (2. 24 ±0. 84) fig/ml, study group: (2. 32 ±0.92) μg/ml, normal value: (1.27 ±0.44) μg/ml]. On the post±operative 7 day, the plasma free hydroxyproline level of study group [ (4. 31 ±1. 05) μg/ml] was significantly higher than that of control group [ (3. 04± 1. 01) μ/ml] (P = 0.002). The wound healing time of study group [ (29. 7±5.3) d] was shorter than that of control group but with± out significant difference [ (33. 3 ±7.5) d, P = 0. 14 ]. Conclusion The intravenous supplementation of glutamine dipeptide may increase the plasma hydroxyproline level after operation and thus promote wound healing.
RESUMO
Objective To explore the repair of the open compound wounds in lower extremities caused by multiple factors. Methotis Transplantation of cutaneous.musculo-cutaneous or greater omentum flaps were applied to 155 patients of open compound lower extremity wounds. Results The wound healing rate following first operation was 50% and that following two operations was 14.8%.While the wounds were healed in 7.7% of patients after three operations. Conclusion Transplantations of cutaneous,musculo-cutaneous or greater omentum flaps ale effective to repair and reconstruct the open compound lower extremity wounds.
