Pre-shaping double-lumen endotracheal tubes based on video laryngoscope blade curvature enhances first-attempt intubation success rate in patients undergoing thoracoscopic surgery: a randomized controlled trial.

ABSTRACT:

Background

The widespread adoption of video laryngoscopes (VLs) in double-lumen endotracheal tube (DLT) intubation has not resolved controversies regarding their efficacy in improving first-attempt success rates. This study aimed to evaluate the safety and efficacy of pre-shaping DLTs according to the VL blade curvature for tracheal intubation in patients undergoing thoracoscopic surgery.

Methods

A total of 90 patients scheduled for elective thoracoscopic surgery under general anesthesia with left-sided DLT intubation were enrolled. The patients were aged ≥18 years and had an American Society of Anesthesiologists (ASA) physical status I or II. All patients were divided into two groups using a random number table method: a video laryngoscope blade curvature-based pre-shaping
