分析小剂量布比卡因蛛网膜下腔-硬膜外对老年下肢骨折麻醉效果影响

To Analyze the Effect of Sub-dural Bupivacaine Subarachnoid-epidural Anesthesia for Lower Limb Fractures in thes Elderly

目的将小剂量布比卡因蛛网膜下腔联合硬膜外麻醉用于老年下肢骨折患者中,对其麻醉效果进行评价。方法对我院收治的80例下肢骨折老年患者分组研究,2组行硬膜外麻醉,1组行小剂量布比卡因蛛网膜下腔联合硬膜外麻醉,对两组麻醉效果进行分析比较。结果 1组麻醉起效时间相比2组明显更快,而术中使用麻醉药物剂量与2组相比也明显更少(P<0.05);1组并发症率为2.5%,与2组12.5%相比明显更低(P<0.05)。结论小剂量布比卡因蛛网膜下腔-硬膜外麻醉用于下肢骨折老年患者中麻醉效果理想,起效时间更快,对患者影响更小,值得临床应用。

Objective To evaluate the anesthetic effect of low-dose bupivacaine subarachnoid combined with epidural anesthesia in elderly patients with lower limb fractures. Methods 80 elderly patients with lower limb fractures were studied in our hospital. Epidural anesthesia was performed in group 2, and subarachnoid subarachnoid anesthesia with small dose of bupivacaine was performed in the group 1. The two groups of anesthetic effects were analyzed and compared. Results The onset time of anesthesia in group 1 was significantly faster than that in group 2, and the dose of anesthetic drugs used during the operation was significantly lower than that of the two groups（P〈0.05）; The complication rate in group 1 was 2.5%, which was significantly lower than that in the group 2（12.5%）（P〈0.05）. Conclusion The low-dose bupivacaine subarachnoid-epidural anesthesia is ideal for elderly patients with lower limb fractures. The anesthetic effect is better, the onset time is faster, and the impact on the patient is smaller. It is worthy of clinical application.
