全麻复合硬膜外阻滞对高血压病人循环功能的影响

目的 :观察全麻复合硬膜外阻滞对高血压病人上腹部手术循环功能的影响。方法 :对4 0例术前合并I、II期高血压择期行上腹部手术的病人随机分为全身麻醉组 (GA组 ,2 0例 )和全麻复合硬膜外阻滞组 (GA EA组 ,2 0例 )。观察围术期麻醉前、插管时、拔管时MAP、HR .RPP等变化。结果 :插管及拔管时 ,GA组MAP、HR、RPP均明显高于麻醉前值 (P <0 .0 1) ;GA十EA组明显低于麻醉前值 (P<0 .0 1) ;两组间比较有非常显著性差异 (P <0 .0 1)。结论 :全麻复合硬膜外阻滞能有效地降低高血压病人麻醉手术中应激反应引起的循环变化 ,只要掌握的好是高血压病人较好的麻醉方式。

Effects of combination of general and epidural anesthesia on hemodynamics for hypertensive patients

Objective: To observe the influences of combined general and epidural anesthesia on hemodynamics for upper abdominal surgery in hypertensive patients.Methods: 40 cases with stage I, II hypertension were randomly divided into two groups,general anesthesia (GA group, 20 cases) or combined general and epidural anesthesia(GA EA group, 20 cases) . MAP, HR, RPP were monitored in persurgical period, before anesthesia, intubation, extubation. Results: During intubation and extubation in GAgroup MAP, HR, RPP were significantly higher than before anesthesia (p<0. 01). GA EAgroup were significantly lower than before anesthesia (p<0. 01) . In two groups MAP,HR, RPP were significantly different(p<0. 01) . Conclusions: GA EA reduce the stress response hemoJynamics during upper abdominal operation in hypertensive patients.It is a preferred proceduce in hypertensive patients.
