根因分析
夹闭存在空气泄漏或完整性受损的水封系统胸管会困住胸腔内空气，将单纯性气胸转化为危及生命的张力性气胸。
English
Clamping a chest tube with a water seal system that has an air leak or is not intact can trap air in the pleural space, converting a simple pneumothorax into a life-threatening tension pneumothorax.

-
夹闭前，确保水封腔完整：检查是否有持续冒泡（表示空气泄漏），且水位在2厘米标记处。如有冒泡，请勿夹闭。改用单向阀（Heimlich阀）进行转运。如无冒泡且系统完整，短暂夹闭转运（30分钟以内）在持续监测下可接受。
-
如果转运需要夹闭（例如防止断开），使用带有锁定机制的商用胸管夹。将夹子放置在靠近胸壁的位置以最小化死腔。记录夹闭时间，并确保患者携带氧气和减压针转运。到达后立即松开夹子并重新连接新的引流系统。
-
考虑使用带有内置水封且无需夹闭的便携式胸腔引流系统（例如Pleur-evac Sahara）。这些系统专为转运设计，无需夹闭即可维持水封。
无效尝试
常见但无效的做法:
-
Assuming that clamping is always safe for transport because it prevents accidental disconnection
75% 失败
Clamping without verifying water seal integrity can cause tension pneumothorax if there is an air leak. The water seal chamber must show no bubbling and the system must be intact before clamping.
-
Believing that a chest tube can be clamped for any duration as long as the patient is monitored
60% 失败
Even with monitoring, a tension pneumothorax can develop rapidly (within minutes) and is often unrecognized until the patient becomes hypotensive or hypoxic.
-
Using a hemostat to clamp the tube without checking if the clamp is sterile or if it might damage the tube
50% 失败
Non-sterile clamps can introduce infection; crushing the tube can cause permanent damage and leakage. Also, the clamp may slip off during transport.
