First-pass success rate and predictive factors for stylet use in videolaryngoscopic intubations with a Macintosh blade: a prospective observational study.

ABSTRACT:

Purpose

The aim of this study was to evaluate the first-pass success rate of videolaryngoscopic intubations without a stylet using a Macintosh blade and to identify predictive factors for successful intubation.

Methods

We conducted a prospective observational study of 224 adult patients scheduled for elective videolaryngoscopic intubations using a Macintosh blade. We excluded patients who had cervical spine issues, airway disease, anticipated difficult intubation, or a body mass index > 35 kg·m^-2, or who required rapid sequence induction. We initially attempted intubations without a stylet, with laryngeal manipulation on the second attempt if needed, and a stylet added after two failures. We evaluated the first-pass success rate and identified predictive factors u
