右美托咪定预防老年男性患者全麻术后因留置尿管引起的躁动

Dexmedetomidine for prevention of restlessness of elderly male patients due to indwelling catheter after general anesthesia

目的：对麻醉患者全麻诱导前注射右美托咪定后导尿和全麻诱导后导尿的效果进行了对比。方法：选择ASAⅠ-Ⅱ级行开腹胃肠道手术的老年男性患者60例，随机分为2组。组1（右美托眯定组），于麻醉前10min静脉注射右美托咪定0．15-0．2μg/kg后导尿；组2，于麻醉诱导后导尿。记录气管拔管时，拔管后5min，拔管后30min，患者的血压、心率和躁动情况。结果：与组2相比较，组1在麻醉苏醒期的心率、血压更平稳，躁动情况发生更少，有统计学意义。（P〈0．05）。结论：全身麻醉诱导前使用右美托咪定，可以减轻术后因留置尿管引起的疼痛，减少术后躁动的发生。

Objective： to compare the outcomes of catheterization after general anesthesia with or without pre-injection of dexmedetomidine. Method： 60 elderly male patients that would have an ASA stageⅠ-Ⅱ open gastrointestinal surgery were randomly divided into 2 groups： group 1 for dexmedetomidine intervention were injected with 0.15-0.2ug/kg dexmedetomidine 10 min before general anesthesia and catheterization; group 2 for control didn＇t receive dexmedetomidine. 5min and 30min after tracheal extubation, the patient＇s blood pressure, heart rate and restlessness were recorded. Results： during anesthesia recovery, compared with group 2, the patients＇ heart rate, blood pressure were more stable and the incidence of restlessness was also much reduced. The difference was significant （P〈0.05i. Conclusion： pre-administration of dexmedetomidine before general anesthesia can alleviate the pain due to indwelling catheter and can reduce postoperative restlessness.
