简介：目的:对神经外科中行血管介入手术的临床方法进行探讨,分析其麻醉复苏效果。方法:抽取2016年1月-2018年6月间收治的神经外科行血管介入手术病人106例,以随机分配原则,分对照组和实验组各53例,所有病人在全身麻醉下进行手术,术后对照组给予生理盐水注射,实验组给予盐酸纳美酚注射,观察其麻醉效果及对病人消化系统的影响。结果:实验组给药至拔管用时(2.51±0.83)min,对照组给药至拔管用时(8.46±0.97)min,两组相比有明显区别(P<0.05);治疗前两组各项消化系统症状评分对比差异无显著性(P>0.05),治疗后对照组腹痛、腹胀、嗳气、早饱、反酸等消化系统的症状评分皆高于试验组(P<0.05)。结论:在神经外科性血管介入术全麻后使用盐酸纳美酚可缩短病人恢复意识的时间,使复苏更为平稳,安全性较高,值得推广。

简介：目的:探讨分析5S管理对消化科手术室优质护理服务的促进作用。方法:选取2017.03-2018.03在我院进行5S管理的60例消化科手术室工作记录作为研究组,同期未进行5S管理的60例消化科手术室工作记录作为对照组,对比其护理情况。结果:研究组术间、术后物品归位摆放程度,患者衣物及时归还率以及护士综合素质合格率显著高于对照组,手术准备时间显著低于对照组,两组间差异性显著,P<0.05,有统计学意义,对照组患者术后不良反应发生率也低于对照组,P<0.05,有统计学意义。结论:在消化科手术室优质护理服务中采用5S管理可提高护士的自主护理意识,降低消化科患者的不良反应发生率,有利于优质护理服务的顺利进行。
