概括
胸腔切开过程中墙壁吸收和重力排水会导致类似的胸部不适. 这项随机试验在两种大容量液体排水方法之间没有发现疼痛或呼吸困难的显著差异.
科学领域:
- 肺部病理学 肺部病理学
- 干预程序 干预程序
- 医疗器械 医疗器械
背景情况:
- 之前的研究表明,手动注射器吸入和胸腔疏通引力排水之间胸部不适没有差异.
- 壁吸的负压梯度对胸部疼痛对胸腔切除术后胸痛的影响仍未得到研究.
研究的目的:
- 为了确定墙壁吸液排水是否会在接受大体积胸腔切除术的患者中引起比重力排水更大的胸部不适.
主要方法:
- 一个多中心,单盲,随机对照试验比较了墙壁吸液与重力排水,用于大体积胸腔切除 (≥500毫升).
- 患者在手术前,手术期间和手术后使用视觉模拟尺度对胸部不适进行了评分.
- 主要结局是5分钟后的术后胸部不适;次要结局包括呼吸困难,手术时间,液体体积和并发症.
主要成果:
- 在壁吸和重力排水组之间没有观察到手术过程胸部不适的显著差异 (P = .08).
- 二次结果,包括手术后的不适和呼吸障碍,也没有显著差异.
- 排放的液体体积相似,尽管重力排水过程需要大约3分钟的时间. 在肺胸部或重新扩张的肺水腫率上没有发现差异.
结论:
- 使用墙壁吸入或重力排水的胸腔切除会产生相当程度的手术不适.
- 这两种方法在需要大量液体清除的患者中,在呼吸障碍方面都提供了类似的改善.

228
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
