Comparison between ultrasound- and bronchoscopy-guided percutaneous dilational tracheostomy in critically ill patients: A retrospective cohort study

摘要

Introduction: Percutaneous dilational tracheostomy (PDT) is routinely performed in the intensive care unit with bronchoscopic guidance. Recently, ultrasound (US) has emerged as a new safety adjunct tool to increase the efficacy of PDT. However, the available data are limited to case series without any control group. Hence, a retrospective cohort study was designed to evaluate the efficacy of US-guided PDT compared with bronchoscopy-guided PDT.
