To Tube, or Not to Tube: Comparing Ventilation Techniques in Microlaryngeal Surgery

Abstract

Objectives/Hypothesis: The objective of this study was to compare ventilation techniques utilized in microlaryngeal surgery. Study Design: Retrospective cohort study. Methods: Two-hundred surgeries performed from May 1, 2018 to March 1, 2020 and stratified as intubated, intermittently intubated (AAIV) or apneic. Patient demographics, comorbidities, anesthetic agents, intraoperative parameters/events, and complications were studied and compared across the three groups using inferential analyses. Results: Median body mass index in the AAIV group was significantly higher (33 vs. 29; P =.0117). Median oxygen nadirs were lower in AAIV cases (81% vs. 91–92%) while CO2 peak measurements were lower (33 mmHg vs. 48 mmHg) in the fully apneic cohort which were significantly shorter cases (P
