摘要
目的观察右美托咪啶静脉注射治疗小儿全身麻醉后寒颤的安全性和有效性。方法选择40例年龄6~16岁的全身麻醉后的儿童,随机分为曲马多组（n=20）,右美托咪啶组（n=20）,均在出现寒颤时静脉给药。T组给予曲马多2mg/kg,D组给予右美托咪啶0.3μg/kg,5~10min缓慢推注,若在推注过程中寒颤停止,即停止推药。并开始记录患者10min内,寒颤的转归情况,以及出现的不良反应。结果①右美托咪啶组治疗寒颤的效果明显优于曲马多,且无寒颤再发现象;②右美托咪啶组心率和血压都有所下降,但都在正常范围内;③右美托咪啶组的恶心呕吐的发生率明显低于曲马多组。结论右美托咪啶静脉注射能迅速解除寒颤,降低寒颤阈值,减少寒颤再发,安全可靠。
Objective To observe the safety and realibility of Dexmedetomidine treatment of shivering in children after general anesthesia.Methods Forty shivering patients undergoing general anesthesia were randomly allocated to two groups,（20 cases in each group）,the dexmedetomidine group（Group D）,the tramadol group（Group T）.When shivering occurs,0.3μg / kg of diluted with saline to 10ml was slowly injected,over 5 ~ 10min,withdrawed as soon as the shivering stops.And 2mg / kg of tramadol were injected intravenously in group T over 5 ~ 10min.Results The dexmedetomidine curative effect to the shivering after general anesthesia is much better than tramadol in children.The shivering treated with Dex was no recurrence.The incidence of nausea and vomit in group T were better than group D.The heart rate and MAP of group were declined,but which were in the normal range.Conclusion Dexmedetomidine intravenous injecting can rapidly relieve chills,and reduce recurrence of shivering.The safety and clinical value are positive.
