An analysis of emergency tracheal intubations in critically ill patients by critical care trainees

Introduction We evaluated intensive care medicine trainees' practice of emergency intubations in the United Kingdom. Methods Retrospective analysis of 881 in-hospital emergency intubations over a three-year period using an online trainee logbook. Results Emergency intubations out-of-hours were less frequent than in-hours, both on weekdays and weekends. Complications occurred in 9% of cases, with no association with time of day/day of week (p = 0.860). Complications were associated with higher Cormack and Lehane grades (p=0.004) and number of intubation attempts (p < 0.001), but not American Society of Anesthesiologist grade. Capnography usage was ≥99% in all locations except in wards (85%; p = 0.001). Ward patients were the oldest (p < 0.001), had higher American Society of Anesthesiologist grades (p < 0.001) and lowest Glasgow Coma Scale (p < 0.001). Conclusions Complications of intubations are associated with higher Cormack and Lehane grades and number of attempts, but not time of day/day of week. The uptake of capnography is reassuring, although there is scope for improvement on the ward
