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

Abstract

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.
