Endoscopic percutaneous dilatational tracheostomy is at least as safe as standard open tracheostomy in the operating room (OR). Recently, a single dilator was introduced to accomplish dilatation of the tracheal aperture in one step, thus obviating the need for multiple graduated dilators. Experience with endoscopic percutaneous tracheostomy (PCT) using the single dilator in 40 patients to date supports the premise that the procedure is safe, rapid, and technically simple. In the study by Añon et al, two very different techniques, are compared: the Ciaglia percutaneous dilatational tracheostomy technique using multiple dilators and the Griggs percutaneous technique using guidewire-dilating forceps. Although relative complication rates for the two techniques are not significantly different, both procedures are performed in a 'blind' fashion, without the benefit of a bronchoscope. The reported incidence of serious complications in this study is high, and almost certainly avoidable with the addition of direct bronchoscopic visualization. Operative time is reported to be shorter with the Griggs technique, but this finding is unlikely to hold true for the single dilator technique, which reduces procedure time to less than 15 min. This author's experience with bedside endoscopic PCT using the single dilator indicates that it is a safe, rapid and cost-effective procedure with a low complication rate.
内镜下经皮扩张气管切开术在手术室中的安全性至少与标准开放性气管切开术相当。最近,一种单一扩张器被引入,可一步完成气管造口的扩张,从而无需使用多个分级扩张器。迄今为止,对40例患者使用单一扩张器进行内镜下经皮气管切开术(PCT)的经验支持了该手术安全、快速且技术简单的前提。在Añon等人的研究中,比较了两种截然不同的技术:使用多个扩张器的Ciaglia经皮扩张气管切开术技术和使用导丝扩张钳的Griggs经皮技术。尽管这两种技术的相对并发症发生率没有显著差异,但两种手术都是在“盲目”状态下进行的,没有支气管镜的辅助。该研究中报道的严重并发症发生率很高,而通过直接支气管镜可视化几乎肯定可以避免。据报道,Griggs技术的手术时间较短,但这一发现对于单一扩张器技术不太可能成立,后者可将手术时间缩短至不到15分钟。作者使用单一扩张器进行床边内镜PCT的经验表明,这是一种安全、快速且具有成本效益的手术,并发症发生率低。
