Background: The Songklanagarind airway management outside the operating room practice guidelines were first developed and implemented in 2018. This study aimed to determine the success rate of emergency call for endotracheal intubation outside the operating room and other outcomes. Methods: This retrospective cohort study was conducted from January 2018 until December 2020. We determined intubation performances and outcomes of endotracheal intubation outside the operating room in patients with anticipated difficult intubation, by either anesthesiologist staff or residents. The outcomes were compared from the three years of study period. Results: During the three-year period, there were 171 airway consultations: divided into 26, 54, and 91 intubations in 2018, 2019, and 2020. The overall success of intubation was 98.8%. The rate of successful intubation in the emergency unit was significantly lower (87.5%) compared to the rate of successful intubation in the intensive care units (100.0%) and general wards (100.0%) (P=0.008). Residents claimed 76.9% of intubation success. The median waiting time was five minutes. The intubation success and the waiting time were not different among years. Conclusion: There was not significantly different between the success rate of intubation within each year. Compared to other settings, intubation performed in the emergency unit carried the greater chance of failure.
