预先静注布托啡诺对腰硬联合麻醉后寒战反应的影响

目的 观察预先静脉注射布托啡诺对下腹部手术腰硬联合麻醉后寒战反应的影响.方法 选择60例ASA Ⅰ～Ⅱ级下腹部手术腰硬联合麻醉患者,随机分为两组A组(观察组)、B组(对照组),A组在腰硬联合麻醉前10 min静脉注射布托啡诺1 mg/5 ml,B组注射5 ml生理盐水.观察麻醉后两组患者寒战发生的情况及镇静评分.结果 观察组寒战反应发生率明显低于对照组(P<0.01),镇静评分满意率观察组显著高于对照组(P<0.05).结论 预先静脉注射布托啡诺能够有效地预防下腹部手术腰硬联合麻醉后寒战的发生,且镇静效果满意.

The effects of pre-treatment with butorphanol on postanesthesia shivering in patients undergoing operation of hypogustric zone after combined spinal-epidural anesthesia

Objective To assess the effects of pre-treatment with butorphanol on postanesthesia shivering in patients undergoing operation of hypogastric zone after combined spinal-epidural anesthesia. Methods Sixty patients (ASA Ⅰ,Ⅱ) undergoing operation of hypogastric zone were randomly assigned into two groups(n = 30). Group A(test group) : The patients were injected intravenously with butorphanoi 1 mg/5 ml at the time of 10 min before combined spinal-epidural anesthesia. Group B(control group) : The patients were injected intravenously with 0.9% saline 5 ml at the same time point. The development of shivering and sedation degree was observed after the anesthesia. Results The incidence rate on shivering in test group was significantly lower than that in control group(P <0.01). While the satisfaction rate on sedation score in test group was higher than that in control group(P < 0.05). Conclusion Pre-treatment with butorphanol is effective and safe on poatanesthesia shivering in patients undergoing operation of hypogastric zone.
