咪唑安定、异丙酚麻醉诱导在老年人腹腔镜手术中的应用

目的 :观察咪唑定安、异丙酚麻醉诱导在老年人LC术的诱导效果和呼吸、循环的变化。方法 :选择ASAⅠ～Ⅲ级的老年LC手术患者 6 0例 ,随机分 3组 ,分别选用不同的麻醉诱导药物 ,Ⅰ组 (n =2 0 )采用咪唑安定 0 1mg/kg ,Ⅱ组 (n =2 0 )采用异丙酚 2 0mg/kg ,Ⅲ组 (n =2 0 )采用咪唑安定 0 0 5mg/kg与异丙酚1 0mg/kg合用。结果 :咪唑安定或异丙酚诱导 ,血压、心率波动较大 ,异丙酚组呼吸抑制程度明显高于其它两组 ,咪唑安定与异丙酚合用 ,麻醉诱导时间短、效果确切 ,整个诱导插管期间 ,血循环变化轻微 ,注药后虽有一过性呼吸抑制 ,但充分供氧后均可迅速恢复。结论 :咪唑安定合用异丙酚是老年人腹腔镜胆囊切除术的较为合理的麻醉诱导方法

Anesthetic induction by Midazolan and Diprivan in laparoscopic surgery in senile patients

Objective:To observe the effect of anesthetic induction by Midazolan and Diprivan in laparoscopic cholecystectomy(LC) in senile patients.Methods:Sixty senile patients before laparoscopic cholecystectomy(ASA Ⅰ Ⅲ) were randomized into three, groups:group 1(n=20)received Midazolan 0 1 mg/kg, group 2(n=20) received Diprivan 2 0 mg/kg, group 3(n=20) received both Midazolan 0 05mg/kg and Diprivan 1 0mg/kg.Results:The blood pressure and heart rate of every patient fluctuated obviously both in group 1 and in group 2. The degree of pneumatic suppression of every patient in group 2 was much higer than that of other groups. In group 3, the time of anesthetic induction was short and its effect was reliable, the circulatory fluctuation was slight as well. Though temporary pneumatic suppression occured after injection, it recovered promptly with enough oxygen.Conclusions:Using both Midazolan and Diprivan is rather rational in LC in senile patients.
