镇静对腹股沟疝修补术中痛觉的影响

Effect of sedation on pain perception in herniorrhaphy patients

目的：观察不同镇静药对局麻下腹股沟疝修补术过程中痛觉感受的影响。方法：选择拟在局麻下行腹股沟疝修补术的男性患者60例,年龄20~60岁,ASA分级Ⅰ~Ⅱ级。随机分为对照组（ C组）、咪达唑仑镇静组（ M组）和右美托咪定镇静组（ D组）,每组20例。观察记录各组患者术中痛觉评分及术后满意度评分。结果：与C组比较,M组患者术中的痛觉评分增高而满意度评分无显著差异,D组患者痛觉评分降低而满意度评分增高。结论：镇静对痛觉的影响与使用的镇静药物相关,对于局麻下行腹股沟疝修补术的患者咪达唑仑镇静时可增加痛觉感受而右美托咪定可降低痛觉感受。

Objective：To study the effect of sedation on pain perception in herniorrhaphy patients. Methods：Sixty patients, aged 20~60 year,male,ASAⅠorⅡ,who were scheduled for herniorrhaphy under local anesthesia were randomly allocated into three groups：contral group（ group C） ,midazolam group（ group M） and dexmedetomidine group（ group D） . Postoperative pain scores and satis-faction scores were recorded in three group. Results：Compared with group C,pain perception increased significantly,but the degree of patient satisfaction had no difference in group M;however,the pain perception decreased and the degree of patient satisfaction increased significantly in group D. Conclusion：The effects of sedatives on pain perception are drug-related. Notably, midazolam increases pain perception,whereas dexmedetomidine produced analgesia in patients during herniorrhaphy under local anesthesia.
