Yonsei Med J:小儿整形外科术中辅助应用右美托咪定的镇痛的效果优于芬太尼

2017-05-27 MedSci MedSci原创

阿片类药物通常用作局部麻醉剂的硬膜外佐剂,但与潜在的严重副作用(如呼吸抑制)的发生相关。本研究旨在对比右美托咪定与芬太尼作为罗哌卡因硬膜外阻滞在小儿骨科手术中的有效性和安全性。 研究共纳入了60名择期性手术的儿童患者(3 - 12岁),采用患者自控镇痛(PCA)。手术结束前30分钟患者经硬膜外导管接受0.2%罗哌卡因(0.2毫升/公斤)以及右美托咪定(1µg/kg)或芬太尼(1µg/kg)。

阿片类药物通常用作局部麻醉剂的硬膜外佐剂,但与潜在的严重副作用(如呼吸抑制)的发生相关。本研究旨在对比右美托咪定与芬太尼作为罗哌卡因硬膜外阻滞在小儿骨科手术中的有效性和安全性。

研究共纳入了60名择期性手术的儿童患者(3 - 12岁),采用患者自控镇痛(PCA)。手术结束前30分钟患者经硬膜外导管接受0.2%罗哌卡因(0.2毫升/公斤)以及右美托咪定(1µg/kg)或芬太尼(1µg/kg)。术后观察硬膜外PCA的罗哌卡因量、术后疼痛强度、镇痛药的需要、躁动以及其他不良反应。

结果,右美托咪定组术后6小时,硬膜外罗哌卡因的平均剂量明显低于芬太尼组(0.029±0.030 mg/kg/h vs. 0.053±0.039 mg/kg/h, p=0.012)。术后6小时的中位数疼痛评分,右美托咪定组也低于芬太尼组[0 (0–1.0) vs. 1.0 (0–3.0), p=0.039]。然而,在整个研究期间两组对抢救镇痛的需要并无明显差异。

总而言之,该研究发现在小儿下肢大手术中,使用右美托咪定作为硬膜外辅助药物的镇痛效果以及局部麻醉保留效应明显优于芬太尼。

Lancet:北大一院研究发现右美托咪定预防非心脏手术后谵妄,安全且有效

谵妄是在65岁以上患者经常发生的术后并发症,并预示着不良后果。研究人员调查了低剂量右美托咪定(一种高度选择性的α2肾上腺素受体激动剂)是否可以在老年患者非心脏手术后安全地减少谵妄的发病率。来自中国的研究人员在中国北京市的两所三级医院进行了一项随机、双盲、安慰剂对照试验。研究人员纳入了年龄在65岁或以上,非心脏手术后被送往重症监护病房的患者,这些患者均签署知情同意书。研究人员使用计算机生成的随机序列

JAMA:机械通气的败血症患者:右美托咪定镇静是否有生存获益?

右美托咪定可为进行机械通气患者提供镇静作用,但其对败血症患者结局有何影响呢?2017年3月,发表在《JAMA》的一项研究显示,在需要机械通气的患者中,同未使用右美托咪定相比,使用右美托咪定不会显着改善死亡率或无呼吸机天数。重要性:右美托咪定可为经历机械通气患者提供镇静作用;但是,其对败血症患者的死亡率和无呼吸机天数的影响尚未被很好地研究。目的:考察右美托咪定的镇静策略是否能改善进行机械通气的败血症

右美托咪定在区域阻滞中的应用进展

右美托咪定(dexmedetomidine, Dex)作为一种新型高选择性α2肾上腺素能受体激动剂,具有镇静、镇痛、抗焦虑及抗交感神经的作用,无明显呼吸抑制,且对心、脑和肾等器官功能具有一定的保护作用。目前Dex复合局麻药已安全有效地应用于区域阻滞,起到改善麻醉效果、稳定血流动力学、优化术后镇痛的作用,但其作用机制还不完全明确,且应用期间也有低血压、心动过缓及过度镇静等不良反应发生。本文就De
