注射用内给氧治疗呼吸衰竭的优越性 总被引:3,自引:0,他引:3
目的 对比观察静脉注入过氧化氢碳酸酰胺与鼻导管给氧法在治疗低氧血症方面的疗效。方法 全组40例,实验组20例,用静脉注入过氧化氢央酸酰胺;对照组20例,用鼻塞给氧法。并以血气分析来判断疗效。结果 实验组与对照组在和药或吸氧后PaO2均有升高,但对照组吸氧后PaCO2明显升高,而实验组注射用内给氧后PaCO2无明显升高。结论 注射用内给氧是治疗低氧血症的一种安全有效,应用范围很广的制剂。 相似文献

对于低氧血症,临床常用氧治疗和机械通气的方法纠正,此2种方法对于心肺功能差者效果较差。静脉注射碳酸酰胺过氧化氢(内给氧)给氧不依赖肺功能而提高血氧分压,可用于治疗低氧血症、胎儿宫内窘迫等。全麻诱导时气管插管操作,要求迅速准确,操作时间长会引起患者窒息, 相似文献

目的 观察注射用内给氧预防围麻醉期缺氧的疗效。方法 硬膜外麻醉手术病人 46例 ,随机分为对照组 (1 5例 )、吸氧组 (1 5例 )和内给氧组 (1 6例 )。吸氧组采用鼻前庭吸氧 2 .5L/min ;内给氧组单纯滴注注射用内给氧。麻醉方法三组相同。比较三组病人在术中、术后的动脉血氧分压和氧饱和度。结果 在监测的三个时刻 ,吸氧组和内给氧组的动脉血氧分压指标和动脉组氧饱和度指标均明显高于对照组 ,且在吸氧组和内给氧组间比较 ,监测的两个指标差异不显著。结论 注射用内给氧能显著增加血液的氧含量 ,对防治缺氧有一定意义 相似文献

益生注射液对人内皮细胞缺氧再给氧损伤的拮抗机理研究 总被引:8,自引:0,他引:8
目的 探讨内皮细胞缺血再灌注损伤及中药益生注射液对其的拮抗机理。方法 用无糖培养基在无氧条件下培养使人脐静脉内皮细胞株ECV304缺氧1.5小时,然后以含糖培养基,在5%CO2和37℃条件下给氧培养5小时,建立内皮细胞缺氧再给氧模型,以模拟体内缺血再灌注对血管内皮细胞的损伤,并用益生注射液干预其缺氧再给氧过程,荧光染色显示胞内钙离子与线粒体,细胞化学染色显示胞内琥珀酸脱氢酶(SDH)和乳酸脱氢酶(LDH)活性,并检测细胞培养液中超氧化物歧化酶(SOD),丙二醛(MDA)和一氧化氮(NO)浓度。结果 缺氧再给氧使ECV304细胞变圆,收缩、脱落,细胞内钙离子含量增高,线粒体膜电位减弱,SDH活性下降,LDH活性增高,培养液中SOD与NO含量减少,而MDA浓度增高;用益生注射液干预后,ECV304细胞形态基本恢复正常,上述多项检测指标的改变得以逆转。结论 缺氧再给氧导致ECV304细胞发生脂质过氧化,胞内钙离子超载,SOD活性及NO水平降低,线粒体功能受损,益生注射液可使上述变化得意以逆转,从而拮抗内皮细胞缺氧再给氧损伤。 相似文献

Transtracheal oxygen therapy for refractory hypoxemia 总被引:2,自引:0,他引:2
Eight patients with chronic severe and refractory hypoxemia were treated with a new transtracheal oxygen catheter. All patients demonstrated an arterial oxygen partial pressure of less than 55 mm Hg on high-flow nasal cannula therapy. Refractory hypoxemia was successfully treated in all eight patients following initiation of transtracheal oxygen therapy at 2.5 to 6.0 L/min. Arterial oxygen partial pressure was 50% greater and oxygen flow requirements were 72% less with transtracheal oxygen. There were no complications related to the procedure and oxygen flow rates up to 6 L/min were well tolerated. Although four patients died, four remain clinically stable with adequate oxygenation at up to 20 months' follow-up. All eight patients experienced an improvement in quality of life with transtracheal oxygen. 相似文献

Effective percutaneous oxygenation and ventilation can be achieved through the use of transtracheal catheters. A graphic study of pressure-flow requirements through different-sized catheters can serve as a guide for the caliber and driving pressure requirement to obtain optimal oxygen flow. 相似文献

我院使用液态氧中心供氧一年多来,与原钢瓶氧供氧相比较,其优越性主要体现在:由于通过管路到使用终端,用截止阀门控制使用,所以安全、快捷、方便,提供的液化气态氧,因减少了压缩、充灌以及换瓶等环节,其纯度可达99.9%;液态氧的利用率可达90%以上,高于钢瓶氧(10~15)%;同时便于管理,减轻了劳动强度;而且经济实惠,大大节约了开支,经统计可节约开支四分之三. 相似文献

临床工作过程中,环甲膜穿刺一直是一种紧急气道处理的重要手段.然而环甲膜穿刺成功后,因穿刺针过细,气道阻力太高,大多数麻醉机的气道正压通气很难满足生理需要,只能采用不太常用的喷射通气方式.为此,本文介绍一种就地取材、多个穿刺针联合通气的新方法. 相似文献

Of 4,200 patients admitted to an acute-care county hospital, 126 (3%) were proved to have pulmonary tuberculosis, among whom 35 (28%) had several sputum smears negative for acid-fast bacilli. On transtracheal aspiration, 31 to 35 had acid-fast bacilli in the aspirate. Eighteen of these 35 (51%) patients had associated infections caused by aerobic or anaerobic bacteria. Tuberculin skin tests were negative in 14 of 35 patients with negative sputum specimens (40%). Ten of 18 patients (56%) with associated bacterial infections had negative skin tests to purified protein derivative. Smear and culture of transtracheal aspirate for tubercle bacilli may be invaluable in establishing the diagnosis when pulmonary tuberculosis is suspected. 相似文献
