Percutaneous dilatational tracheostomy (PDT) continues to gain in popularity as a bedside method for tracheostomy placement in the intensive care unit. Here, we present a description of ultrasound technique and two case examples to show the utility of bedside ultrasound screening to select patients with appropriate anatomy for PDT.
We have instituted a protocol at our institution to use bedside screening ultrasound to confirm appropriate anatomy prior to PDT. In this report, we present our ultrasound methodology and present two cases with clear correlations between screening ultrasound findings and intraoperative findings.
We describe an easily applied method for pretracheal ultrasound screening. To show the utility of this screening technique, we then present two example cases showing pretracheal vascular structures seen on ultrasound and during open operative exploration.
Bedside ultrasound screening allows for easy identification of pretracheal vascular structures that might pose a hemorrhage risk during PDT.
经皮扩张气管切开术（PDT）作为一种在重症监护病房床边进行气管切开术的方法，越来越受到欢迎。在这里，我们描述了超声技术，并提供了两个案例示例，以展示床边超声筛查在选择适合 PDT 的患者方面的实用性。
我们在机构中制定了一项方案，使用床边筛查超声来确认 PDT 前的适当解剖结构。在本报告中，我们介绍了我们的超声方法，并提供了两个病例，这些病例的筛查超声结果与术中结果之间存在明确的相关性。
我们描述了一种简单易用的术前超声筛查方法。为了展示这种筛查技术的实用性，我们随后提供了两个示例病例，显示了超声和开放性手术探查期间可见的气管前血管结构。
床边超声筛查可轻松识别在 PDT 过程中可能导致出血风险的气管前血管结构。
