Percutaneous dilatational tracheostomy (PDT) is the most commonly used minimally invasive procedure in patients with prolonged mechanical ventilation. However, during the procedure withdrawal, the endotracheal tube (ET) may cause substantial gas leak and sometimes the airway could be lost, and the patient exposed to severe hypoxemia. In order to prevent hypoxemia during ET withdrawal and needle stuck in ET during PDT and also for performing the procedure more safe and easy.
In this study, we introduce a new instrument "downpipe endotracheal tube" that has been registered as a patent and examined it in eight patients to confirm practical advantage of this tube.
These patients were five female and three male, with a mean weight of 71.7 kg and the mean age of 65.12 years. The cause of tracheostomy was difficult weaning from mechanical ventilation.
The procedure was safe in all cases. We did not find any complications during the procedure.
经皮扩张气管切开术（PDT）是长期机械通气患者最常用的微创手术。然而，在操作过程中拔出气管内插管（ET）时，可能会导致大量气体泄漏，有时气道可能会丢失，患者会暴露于严重低氧血症中。为了在拔出ET期间预防低氧血症以及在PDT期间防止穿刺针卡在ET中，并且使操作更安全、简便。
在本研究中，我们介绍了一种已获得专利的新型器械“下行气管内插管”，并在8例患者中对其进行了检查，以确认该插管的实际优势。
这些患者中5例为女性，3例为男性，平均体重71.7kg，平均年龄65.12岁。气管切开的原因是机械通气撤机困难。
所有病例的操作均安全。我们在操作过程中未发现任何并发症。
