摘 要:目的:研究乙醇对丙泊酚催眠效应的影响。方法①按分层随机区组设计将32只小鼠分为4组(n=8):30%乙醇组(E30组)、40%乙醇组(E40组)、50%乙醇组(E50组)、60%乙醇组(E60组)。观察小鼠翻正反射消失的比率,确定合适的乙醇浓度。②按分层随机区组设计将40只小鼠分为5组(n =8):生理盐水组(NS组)、脂肪乳组(F 组)、乙醇组(E 组)、丙泊酚组(P 组)及联合组(乙醇+丙泊酚,U 组)。观察小鼠翻正反射消失率、潜伏期以及翻正反射消失持续时间。结果与 E 组及 P 组相比,U 组翻正反射消失率明显升高(P <0.01),潜伏期明显缩短(P <0.01),翻正反射消失持续时间明显延长(P <0.01)。结论乙醇可显著增强丙泊酚的催眠效应,加强中枢抑制作用。Objective To investigate the effects of ethanol on the hypnosis induced by propofol.Methods Based on stratified randomization, 32 mice were divided into four groups (n =8), according to their different treatments of 30%ethanol (Group E30), 40% ethanol (Group E40), 50% ethanol( Group E50) and 60% ethanol (Group E60).Then, the righting reflex test was performed to observe the rate of LOR in order to determine the optimum concentration of etha-nol.Based on stratified randomization, anther 40 mice were divided into five groups (n =8), according to their different treatments of normal saline (Group NS), fat emulsion (Group F), ethanol (Group E), propofol (Group P) and a com-bination of ethanol +propofol (Group U).Then, the righting reflex test was performed to observe the rate, latency and duration of LOR.Results Compared with Groups E and P, Group U produced a remarkably higher rate of LOR (P 〈0.01), obviously shorter latency (P 〈0.01), and markedly extended duration (P 〈0.01).Conclusion Ethanol can strengthen the hypnotic effect of propofol, and enhance the inhabitation of the central nervous system.
