Tracheal Intubation by Specialist Paramedics (Critical Care) in a United Kingdom Ambulance Service: a Service Evaluation.

Abstract

BackgroundDrug-free tracheal intubation has been a common intervention in the context of out-of-hospital cardiac arrest for many years, however its use by paramedics has recently been the subject of much debate. Recent international guidance has recommended that only those achieving high tracheal intubation success should continue to use it.MethodsWe conducted a retrospective service evaluation of all drug-free tracheal intubation attempts by specialist paramedics (critical care) from South East Coast Ambulance Service NHS Foundation Trust between 1st January and 31st December 2019. Our primary outcome was first-pass success rate, and secondary outcomes were success within two attempts, overall success, Cormack-Lehane grade of view, and use of bougie.ResultsThere were 663 drug-free tracheal intubations and following screening, 605 were reviewed. There was a first-pass success rate of 81.5%, success within two attempts of 96.7%, and an overall success rate of 98.35%. There were ten unsuccessful attempts (1.65%).ConclusionSpecialist paramedics (critical care) are able to deliver drug-free tracheal intubation with high first-pass success and very high overall success and are therefore both safe and competent at this intervention.
