右美托咪啶在功能性鼻内镜鼻窦手术患者麻醉复苏期中的应用

Application of dexmedetomidine in functional endoscopic sinus surgery during the recovery period of general anesthesia

目的探讨右美托咪啶在功能性鼻内镜鼻窦手术患者麻醉复苏期中的应用效果。方法将40例行功能性鼻内镜鼻窦手术患者,于手术结束前15 min静脉输注右美托咪啶0.6μg/kg,观察患者呛咳、疼痛及躁动情况。结果本组患者呛咳得分(1.2±0.5)分,视觉模拟评分(visual analogue scale,VAS)得分(1.9±0.5)分,躁动得分(1.2±0.4)分。结论对行功能性鼻内镜鼻窦手术患者,于手术结束前15 min静脉输注右美托咪啶,同时做好病情观察,控制给药速度,可使患者在麻醉复苏期处于较安静状态,顺利渡过麻醉复苏期。

Objective To study the effect of dexmedetomidine in the functional endoscopic sinus surgery（FESS） on the recovery period of general anesthesia. Methods Fifteen min before the end of surgery, 40 FESS patients were treated with intravenous infusion of dexmedetomidine at 0.6 μg / kg. The occurrence of cough response, degree of pain and agitation in patients were observed.Result The response score of choking cough of the patients with intravenous infusion of dexmedetomiindine was（1.2 ± 0.5）, the score of VSA was（1.9 ± 0.5）, and the degree of agitation was（1.2 ± 0.4）. Conclusion For those undergoing FESS, postoperative use of dexmedetomidine 15 min before the end of surgery, can not only have an effective effect for reducing the incidence of choking cough and agitation and but also decrease the pain degree so that the patients can live through the general anesthesia recovery period.
