Objective To evaluate the impact of sepsis bundle treatment on morbidity of sepsis or septic shock in burned patients. Methods A retrospective clinical study was conducted on burned patients with severe sepsis or sepsis shock in burn intensive care unit. 95 patients were divided into control group(43 patients) and study group (52 patients)according to their treatment. The relationship between sepsis bundle index and sepsis, septic shock and 28-day mortality respectively were analyzed with logistic regression analysis. The compliance of sepsis bundles,and 28-day mortality were noted. Results The 28-day mortility rate,the mobidity of sepsis and septic shock in study group was lower than that of control group (P ＜ 0. 05). It could be found that 6-hour EGDT and 24-hour EGDT was the independent protective factor of sepsis and septic shock through logistic regression analysis ,and blood gas analysis, EGDT and vasoactive drug were correlated with 28-day mortality(P ＜0. 05). Compliance with sepsis bundles of 6-hour EGDT and 24-hour EGDT in study group was only 51.9%, and 63.2% respectively. Conclusion Sepsis bundle was able to improve survival rate in severe burn patients. Compliance with sepsis bundles in burn medical staff needed a buring improve.

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.

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.
