早期肠内营养联合生长激素在危重烧伤患者救治中的应用研究

目的探讨早期肠内营养联合生长激素在危重烧伤患者救治中的作用。方法将35例严重烧伤（30％～50％TBSA）患者，随机分成肠内营养组（EN组）和肠外营养组（PN组），对比分析两组前白蛋白（PA）、肿瘤坏死因子（TNFα）、空腹微量血糖水平、创面愈合时间、平均住院时间、烧伤脓毒症发生率、应激性溃疡出血和早期胃肠道不耐受的发生率。结果EN平均住院时间较PN组缩短。PN组出现烧伤脓毒症、应激性溃疡和早期胃肠营养不耐受发生率较EN组为高（P〈0．05）。PN组及EN组PA均明显下降，但PN下降更为明显（P〈0．05）。PN组及EN组空腹血糖水明显上升，但EN上升更为明显（P〈0．05）。EN组及PN组CRP、TNFα均明显升高，但以PN组升高为著（P〈0．01）。EN组供皮区、植皮区、深Ⅱ度创面较组缩小（P〈0．01）。结论早期肠内营养联合生长激素能明显改善患者营养状况，降低脓毒症和应激性溃疡等并发症的发生率。

Application of recombinant human growth hormone combined with early enteral nutrition in severely burned patients

Objective To summarize the therapeutic effect of recombinant human growth hormone and early enteral nutrition in severely burned patients. Methods 35 cases were randomly divided into group EN and group PN.Group EN was treated with early enteral nutrition(EEN) and recombiant human growth hormone(rhGH) ,while group PN was given parenteral nutrition. The plasma levels of pre-albumin (PA), C-reactive protein (CRP) , tunmor necrosis factor α(TNFα) ,fasting blood glucose(FBG) were measured after burn injury. Comparision was made in length of hospital stay, wound healing time,incidence of burn sepsis, gastrointestinal stress ulcer bleeding and enteral nutrition intoleranc. Results Incidence of burn sepsis,gastrointestinal stress ulcer bleeding and enteral nutrition intoleranc in group EN were significantly lower than those of group PN(P ＜ 0.05). The serum levels of CRP、TNFα、FBG in group EN were significantly lower than those of group PN (P ＜ 0.05). The serum PA was decreased at all times in two periods and was markedly decreased in group EN(P ＜0.05). Length of hospital stay and the healing time of donor site, deep partial thickness burn wound, skin transplantion area were significantly shortened in group EN compared with group PN. Conclusion Early enteral nutrition was beneficial for the improving of nutrition state of the burn patients,and the reduction of the incidence of burn sepsis and the hospitalization time.
