Complications and degree of difficulty of orotracheal intubation in the Intensive Care Unit before and after the establishment of an intubation protocol for critically ill patients: A prospective, observational study.
Revista española de anestesiología y reanimación. 2023 December 16
OBJECTIVE: The objective of our study was to compare the degree of difficulty and complications related to tracheal intubation in an Intensive Care Unit (ICU) before and after the introduction of an intubation protocol based on the Difficult Airway Society guidelines for the management of tracheal intubation in critically ill adults, published in 2018.
METHODS: Prospective, observational study comparing all intubations performed in our ICU over 2 periods: pre-protocol (January 2015 - January 2019) and post-protocol (February 2019 - July 2022). The material used for intubation, the degree of difficulty, and intubation-related complications were recorded.
RESULTS: During the study period, 661 patients were intubated - 437 in the pre-protocol period (96% by direct laryngoscopy) and 224 in the post-protocol period (53% with direct laryngoscopy, 46% with video laryngoscopy). We observed an improvement in laryngeal view in the post-protocol period compared to the pre-protocol period (Cormack-Lehane ≥ 2b in 7.6% vs 29.8%, p < 0.001), and a decrease in the number of moderate-to-severely difficult intubations (6.7% vs 17.4%, p < 0.001). The first-pass success rate was 92.8% in the post-protocol period compared to 90.2% pre-protocol (p = 0.508). We did not find significant differences in complications between the periods studied.
CONCLUSIONS: Intubations performed in the post-protocol period were associated with improved laryngeal view and fewer cases of difficult intubation compared with the pre-protocol period.
