Cricothyroidotomy competence and injuries using nonmedical equipment: A crossover noninferiority randomised controlled trial in a porcine cadaver model.

Background: International guidelines recommend cricothyroidotomy as a life-saving procedure for 'cannot intubate, cannot ventilate' situations. Although commercially available sets facilitate surgical cricothyroidotomy, regular training seems to be the key to success.

Objectives: The goal was to investigate if trained anaesthetists are able to transfer their skill in one surgical cricothyroidotomy technique to another.
