摘要 目的观察微量泵持续输注瑞芬太尼诱导法的可行性及对气管插管时血流动力学变化的影响,并确定诱导时瑞芬太尼的最佳使用方案。方法ASA分级Ⅰ~Ⅱ级、择期行腹腔镜胆囊手术的患者60例,按随机数字表法分为三组,每组各20例。Ⅰ、Ⅱ、Ⅲ组分别在诱导开始时采用微量泵持续输注瑞芬太尼0.2、03、0.4μg/(kg·min),麻醉诱导用咪达唑仑、依托咪酯、阿曲库铵,于输注瑞芬太尼5min后行气管插管。观察诱导前、诱导后3min、插管即刻及插管后1、3、5min的收缩压和心率。结果三组在插管即刻时收缩压、心率均下降,其中Ⅲ组尤为明显[收缩压降至(91±7)mmHg(1mmHg=0.133kPa)、心率降至(51±6)次/min](P〈0.01),插管后1minⅠ组心率、收缩压较诱导前均明显上升[收缩压升至(142±17)mmHg、心率达到(95±11)次/min](P〈0.01),Ⅱ组与诱导前比较差异无统计学意义(P〉0.05),Ⅲ组心率、收缩压略有升高但仍明显低于诱导前;插管后3、5min,Ⅰ组心率、收缩压有所下降但仍高于诱导前,Ⅱ组无明显变化,Ⅲ组均有所升高但仍低于诱导前。结论微量泵持续输注瑞芬太尼诱导法可安全地应用于临床,三种方案中以0.3μg/(kg·min)速度输注瑞芬太尼,在整个诱导、插管期间血流动力学变化较稳定,可作为较合理的方案推荐给临床。
