INTRODUCTION: Cricothyrotomy is a recommended technique to restore oxygenation in most of guidelines for difficult airway management. A correct location of the cricothyroid membrane (CTM) is fundamental for a proper performance of the technique. Several studies have shown poor accuracy with the identification the CTM by palpation, resulting in a high failure rate of the technique.
OBJECTIVE: The aim of this study was to determine the impact of the patient's neck morphology on the accurate location of the CTM and on the time employed.
MATERIALS AND METHOD: Observational study in which anaesthesiologists and intensivists voluntarily participated in a simulation that consisted of a «cannot intubate, cannot oxygenate» scenario, where they had to locate the CTM, as soon as possible, in 2 selected male patients with different morphological characteristics of the neck. The time was measured from the beginning of CTM palpation to locating it with a marker.
RESULTS AND CONCLUSIONS: A higher body mass index and a higher neck circumference correlated with a 70% location failure rate and with a longer time as compared with a standard model.
