骶管超前镇痛对开胸男性手术患者全麻苏醒期躁动的影响

The effects of sacral preemptive analgesia on emergence agitation in male patients undergoing thoracic surgery

目的观察骶管超前镇痛对开胸手术患者全麻苏醒期躁动(emergence agitation,EA)的影响。方法选择择期全麻下男性开胸手术患者40例,ASA I或Ⅱ级,随机分为两组(n=20):全麻复合骶管超前镇痛组(A组)和单纯全麻组(B组)。A组于全麻诱导前骶管注射0.125%低浓度罗哌卡因和小剂量吗啡2 mg混合液20mL。B组单纯实施全麻。术中监测血流动力学变化,并对A、B两组患者全麻苏醒期躁动、疼痛程度作出评分。结果 A组全麻苏醒期躁动和疼痛程度评分明显低于B组(P<0.05)。结论低浓度罗哌卡因和小剂量吗啡骶管超前镇痛可有效预防或减少开胸手术患者EA的发生。

Objective To explore the effects of sacral preemptive analgesia on emergence agitation （EA） in male patients un- dergoing thoracic surgery. Methods Forty ASA Ⅰ-Ⅱ male patients undergoing thoracic surgery were enrolled in this study. The patients were randomized to receive either general combined sacral preemptive anesthesia （group A） or pure general anes- thesia （group B）. Mean arterial blood pressure （MAP）, heart rate（HR）, were continually monitored. The restlessness score （RS）, pain score were recorded. Results The RS and the pain score were significant lower in Group A than that in Group B （P 〈 0.05）. Conclusion Sacral preemptive analgesia significantly reduces emergence agitation in male patients undergo- ing thoracic surgery.
