Description
Chest tube drainage is a procedure that places a hollow tube into the thoracic cavity to remove air or fluid. It is also called chest tube placement or tube thoracostomy. The goal is to relieve pressure on the lungs so they can re-expand.
Emergency chest tube insertion is used as a definitive tre...

急诊胸腔引流管置入术,即胸腔引流术,是一种用于解除胸腔内异常升高的压力的确定性治疗方法。该操作通过将一根中空导管插入胸腔,以引流积聚的液体或气体。无论病因如何,引流均可缓解肺部受压,使肺重新扩张。
本视频将简要概述胸腔闭式引流术的适应证,然后详细讲解如何进行该操作。
急诊胸腔引流管置入的适应证包括张力性气胸……创伤性血胸……大量胸腔积液……以及脓胸。
发生气胸时,胸膜腔内积聚的空气会使胸膜层分离,从而阻碍呼吸过程中肺的扩张。异常液体积聚,例如血胸、胸腔积液或脓胸等情况,会导致紧贴肺组织的脏层胸膜与构成胸腔内壁的壁层胸膜发生分离。胸膜层之间的这种分离使得胸壁运动与肺运动脱节,引起呼吸困难。此外,胸膜腔内大量空气或液体造成的过高压力可能将纵隔推向远离胸腔...
