摘要
目的通过在腰硬联合麻醉中使用单侧阻滞,探讨减少蛛网膜下腔麻醉对老年患者循环呼吸影响的方法。方法选择择期行单侧下肢手术患者40例,随机分为两组。A组行单侧蛛网膜下腔阻滞;B组行常规腰硬联合麻醉。比较给药后第3、5、10、15、20min时对两组患者平均动脉压(MAP)、心率(HR)、氧饱和度(SpO2)的影响。结果两组患者患侧运动阻滞程度无明显差别(P>0.05),A组的感觉阻滞范围略宽,健侧的感觉运动阻滞A组均较B组为轻,二者差异有统计学意义(P<0.05)。所有患者均顺利完成手术。两组在各个记录点的MAP,及第5、10、15min的HR差别均有统计学意义(P<0.01)。所有患者都未出现呼吸抑制。结论在腰硬联合麻醉中使用单侧蛛网膜下腔阻滞可以满足手术需求,对老年患者的呼吸循环影响轻微,有利于减少老年患者的麻醉并发症。
Objective To evaluate the effects of unilateral spinal anesthesia on elder patients circulation and respiration in order to explore the appropriate methods for decreasing the influences of combined epidural-spinal anesthesia for elder patients. Methods 40 patients undergoing selective unilateral lower limb surgery were randomly divided into 2 groups. Group A underwent unilateral spinal anesthesia, while group B underwent routine combined epidural-spinal anesthesia. The mean artery pressure （MAP）, heart rate （HR） and saturation pulse oxygen （SPO2） after giving the initial local anesthetic doses at the time-points of 3 min, 5 min, 10 min, 15 min and 20 min in both groups were recorded. Results There was no significant difference on the motion block degree in operation side （P〉 0.05 ）. While in the non-operational side, patients in group B showed significant motion block （P〈0.05）. No patients had complications, There were significant differences among MAP and HR in all recording time-points. No patients had respiratory inhibition. Conclusion Unilateral spinal block combined with epidural-spinal anesthesia could supply enough anesthesia for elderly patients surgery with little inhibition on circulation and respiration system, that may minimize the anesthesia related complications.
