摘 要:目的探索应用小剂量多巴胺预防老年病人连续硬膜外阻滞下行胆囊切除术中的迷走神经反射。方法对连续硬膜外阻滞下行胆囊切除术的160例病人采用随机双盲法分为甲乙两组。甲组(实验组)病人麻醉后采用持续小剂量静脉推注多巴胺,乙组(对照组)应用安慰剂。整个麻醉期间监测患者心率(HR),收缩压(SBP),舒张压(DBP)和有无恶心,呕吐及其它不适。结果甲组患者血压、心率变化及出现恶心呕吐等不适者的发生率明显少于乙组。结论在连续硬膜外阻滞下行胆囊切除术时,应用小剂量多巴胺能明显减少病人胆-心反射的发生。Objective To observe the effect of using small dose dopamine in eholecystectomy to reduce gallbaladderheart autonomic nerve reflecx. Methods One hundred and sixty patients undergoing cholecystectomy were divided into two groups randomly with double-blind method. Group A was infused intravenously with small dose dopamine and group B was infi^sed with placebo. The systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), nausea, vomiting and other discomforts were recorded. Results In group A, the incidence of bradycardia, hypotension, nausea, vomiting and discomforts was significantly lower than those of group B (P 〈 0.05). Conclusions Small dose dopamine can reduce the incidence of gallbaladder-heart reflex in cholecystectomy under epidural anesthesia in elderly patients.
