本研究的目的是比较两种药物治疗肝昏迷的效果。将病人分为 A、B 两组。A 组应用支链氨基酸,20%葡萄糖液中含有缬氨酸0.84g、亮氨酸1.1g、异亮氨酸0.9g,最初24h 60ml/h,以后80ml/h;B 组用乳果糖,每日150g 口服或200～300g 灌肠,再加与A 组热卡相等的葡萄糖。将40例连续收治的3～4级肝性脑病病人,用随机抽样法分到两组中,每组20例,每组中各有3例病人因故被剔除,因此,两组各为17例。其年龄、性别、诱发因素和肝功能情况均相似。所有病人在静脉滴注时均禁食,且不接受其它治疗,但诱发因素的治疗例外。如果在48h 内病人的神志恢 The purpose of this study was to compare the effects of two drugs on hepatic coma. The patients were divided into A and B groups. A group of branched chain amino acids, 20% glucose solution containing 0.84g valine, leucine 1.1g, isoleucine 0.9g, the first 24h 60ml / h, after 80ml / h; B group lactulose, each Day 150g orally or 200 ~ 300g enema, plus a group of heat equal to the glucose card. Forty consecutive patients with grades 3-4 of hepatic encephalopathy were randomized into two groups, 20 in each group, with 3 patients in each group being excluded for any reason, so both groups were 17 example. The age, gender, predisposing factors and liver function were similar. All patients were fasted during IV drip and did not receive any other treatment, except for the treatment of predisposing factors. If within 48h the patient’s consciousness recovery
