Hypotensive anesthesia is utilized to reduce bleeding during orthopedic surgery. One of the various drugs that have been used to reduce blood pressure is remifentanil. This study was an attempt to compare the effect of remifentanil with that of electroacupuncture (EA) at DU20 on reducing blood pressure. In this randomized controlled clinical trial, 54 patients undergoing lumbar laminectomy were allocated to two groups. Hypotensive anesthesia was performed through infusion of remifentanil 100 μg/kg/min for the control group, and EA at DU20 acupoint with a frequency of 2-10 Hz and intensity of 1-5 mA for the intervention group. Blood pressure, pulse rate, volume of blood lost and the quality of surgical field were evaluated every 10 min. There were no statistically significant differences between the two groups in terms of the changes in mean arterial pressure (MAP), pulse rate, and the quality of surgical field (P > 0.05). Therefore, EA can be as effective as remifentanil to reduce blood pressure in the patients undergoing lumbar laminectomy.
低血压麻醉用于减少骨科手术中的出血。瑞芬太尼是已被用于降低血压的多种药物之一。本研究旨在比较瑞芬太尼与督脉20穴电针（EA）在降低血压方面的效果。在这项随机对照临床试验中，54例行腰椎椎板切除术的患者被分为两组。对照组通过输注100μg/kg/min的瑞芬太尼进行低血压麻醉，干预组在督脉20穴进行频率为2 - 10Hz、强度为1 - 5mA的电针治疗。每10分钟评估血压、脉搏率、失血量和手术视野质量。两组在平均动脉压（MAP）变化、脉搏率和手术视野质量方面无统计学显著差异（P>0.05）。因此，在腰椎椎板切除术患者中，电针降低血压的效果与瑞芬太尼相当。
