Comparison between Real-Time Ultrasound-guided Percutaneous Dilatational Tracheostomy and Surgical Tracheostomy in critically ill Patients: A Randomized Controlled Trial.

Abstract

Objectives: Tracheostomy is an important procedure for critically ill patients in the intensive care unit (ICU), and percutaneous dilatational tracheostomy (PDT) has gained popularity due to its safety and effectiveness. However, there are limited data comparing ultrasound-guided PDT (US-PDT) with surgical tracheostomy (ST). In our previous study, we reported that US-PDT had similar safety and effectiveness to ST, with a shorter procedure time. However, the study design was retrospective, and the sample size was small. Therefore, we conducted a randomized controlled trial to demonstrate the safety and efficacy of US-PDT compared to ST.

Methods: A total of 70 patients who underwent either US-PDT (n=35) or ST (n=35) were enrolled in the study between October 20, 2020 and July 26, 2022. The patients were randomly assigned to their respective procedures. The data collected included patient clinical characteristics, procedure time and details, complications, duration of ICU stay, time taken for weaning from mechanical ventilation, and hospital mortality.

Results: The procedure time of US-PDT was shorter than that of ST (4.0±2.2 minutes vs. 10.1±4.6 minutes). The incision length of US-PDT was also shorter than that of ST (1.5±0.5 cm vs. 1.8±0.4 cm). There were no statistically significant differences in demographics, procedure details, complications, length of ICU stay, ventilator weaning time, and hospital mortality.

Conclusion: US-PDT has a similar complication rate and shorter procedure time compared with ST. It can be safely and effectively performed in critically ill patients and can serve as a potential alternative to ST.
