研究目的:術後喉嚨痛(Postoperative Sorethroat , POST)是全身麻醉後常見的不良事件,此研究的目的是探討局部使用Ketamine為一種NMDA拮抗劑,在全身麻醉中接受氣道處置的病人對預防術後喉嚨痛的有效性和安全性。 研究設計:隨機對照組試驗之系統性文獻回顧與統合分析 研究方法: 以系統性文獻回顧與統合分析方式,使用PubMed、Cochrane Library、Embase、Ovid Medline、手動搜索進行文獻索引,統計方法採用Review Manger 5.3軟體進行統合分析,並用隨機模式評定效果量,以Cochrane Q test 及I2檢測異質性,並以Funnel plot與Fail safe Number判定有無出版偏差。 研究結果:我們審查了23篇進行文獻回顧及統合分析,包括總共1562名患者,我們的研究結果顯示Ketamine組0-1小時的危險比(RR)為0.55(95%CI:0.44-0.69),2小時,RR 0.50(95%CI 0.36-0.69),在4小時RR 0.53(95%CI 0.46-0.62),在8小時RR 0.42(95%CI 0.32-0.54),在24小時RR 0.46(95%CI 0.37-0.58)。中度至嚴重POST,在0-1小時,RR 0.49(95%CI 0.31-0.79),在2小時,RR 0.23(95%CI 0.08-0.61),4小時RR為 0.21(95%CI 0.12-0.36),在8小時RR為0.21(95%CI 0.11-0.43),在24小時時為RR 0.14(95%CI 0.06-0.30),沒有嚴重的不良反應。 研究結論:我們的結果顯示局部使用ketamine可降低全身麻醉術後喉嚨痛、中度及嚴重喉嚨痛、及聲音沙啞之發生率,可透過術前局部使用ketamine提供預防效果。
Objective: Postoperative sorethroat (POST) is a common adverse event following general anesthesia. This study investigates the effectiveness and safety of topical ketamine, an NMDA antagonist to prevent POST in patients undergoing airway management in general anesthesia. Design: Systemic review and meta analysis of randomized controlled trials Data Source: Pubmed, Cochrane Library, Embase, Ovid Medline, hand search Statistical Analysis: Review manager 5.3 for meta analysis, random effects model for effectiveness, Cochrane Q test and I2 for heterogeneity, Funnel plot and Fail safe number for publication bias. Results: We reviewed 23 trials that included 1,562 patients in total. Our results indicated that the incidence of POST was significantly reduced in the ketamine group with risk ratio(RR)of 0.55 (95% confidence interval CI:0.44-0.69), at 0-1 hour, RR 0.50(95% CI 0.36-0.69) at 2 hour, RR 0.53 (95% CI 0.46-0.62) at 4 hour, RR 0.42 (95% CI 0.32-0.54) at 8 hour, RR 0.46 (95% CI 0.37-0.58) at 24 hour. Moderate to severe POST, RR 0.49 (95% CI 0.31-0.79) at 0-1 hour, RR 0.23 (95% CI 0.08-0.61) at 2 hour, RR 0.21 (95% CI 0.12-0.36) at 4 hour, RR 0.21 (95% CI 0.11-0.43) at 8 hour, RR 0.14 (95% CI 0.06-0.30) at 24 hour. No severe adverse effects were noted. Conclusions: Our results indicate that the incidence of POST, moderate to severe POST, and hoarseness, can be prevented by preoperative use of topical ketamine.
