      Cricothyroidotomy is the final rescue maneuver in difficult airway management. We compared 4 techniques of oxygenation via the cricothyroid membrane in a manikin. The techniques were wire guided, trocar, cannula with jet ventilation, and blade technique (scalpel with endotracheal tube). In the wire-guided group, the time taken to ventilation was slower on all attempts, and there were no successful attempts in <40 seconds. There were no differences between the other groups at any time. Time to ventilation improved with repetition in all groups. Skills were retained at 1 month.
