摘要
目的:观察麻醉前输注6%羟乙基淀粉和乳酸钠林格液减轻蛛网膜下腔-硬膜外联合阻滞麻醉后低血压的效果。方法:选择60例病人随机分为A、B两组,每组30例。其中A组输注6%羟乙基淀粉液500ml,B组输注乳酸钠林格液1000ml。观察蛛网膜下腔-硬膜外阻滞联合麻醉后各组收缩压、心率变化,低血压发生率及麻黄碱的用量。结果:B组在麻醉后收缩压下降较为明显,低血压的发生率较A组明显升高,麻黄碱的用量也较A组大,而心率的变化两组之间无统计学差异。结论:胶体液较晶体液更能有效地预防蛛网膜下腔-硬膜外联合阻滞麻醉后低血压的发生。
Objective：To observate the effects in the prevention of hypotension after subarachnoid- epidural anesthesia with 6% hydroxyethyl starch and lactated Ringer＇s solution venoclysis before anesthesia.Methods： 60 patients were randomly divided into groups A and B,with 30 cases in each group. Group A was administered with HES （6% hydroxyethyl starch,molecular weight 130000） 500 ml, while group B with lactated Ringer＇s solution 1 000 ml.The systolic blood pressure, cental venous pressure,heart rate, the incidence rate of low blood pressure and the amount of ephedrine in each group were observed after anesthesia. Results：After anesthesia,the systolic blood pressure in group B decreased significantly , the incidence was relatively great compared with those in group A, but without statistical difference in heart rate between them. Conclusion：Colloidal solution is more effective than the liquid crystal to prevent the occurrence of hypotension after subarachnoid-epidural anesthesia.
