A descriptive survey of tracheal extubation practices among Indian anaesthesiologists

This study assesses the extubation practices of anaesthesiologists and whether these practices differ from existing guidelines.

The literature related to tracheal extubation was searched and a validated questionnaire was designed to assess practices of tracheal extubation. The questionnaire included techniques, manoeuvres, preparation, timing and plan of extubation. The survey link was shared with eligible participants. The responses were assessed using Statistical Package for Social Sciences (SPSS) software.

Of the 1264 respondents, 66.8% keep difficult airway cart ready only when difficult extubation is anticipated. Only 12.3% of respondents perform deep extubation with supraglottic airway device (SAD) exchange while 73.3% of respondents perform awake extubation with pharmacological control for preventing haemodynamic fluctuations. In the case of anticipated difficult extubation, 48.3% anaesthesiologists prefer the airway exchange catheter (AEC) exchange technique. Of all, 84.8% anaesthesiologists administer 100% oxygen before performing extubation and 81.7% continue to oxygenate during and 83.9% provide oxygen after extubation in all patients. In the case of suspected airway edema or collapse or surgical cause for airway compromise, 70% anaesthesiologists perform a leak test. The most preferred plan of extubation in patients with suspected airway collapse after surgery is direct extubation in fully awake position (54.6%). In patients with anticipated difficult extubation, 50.8% anaesthesiologists prefer to ventilate for 24 hours and reassess.

We observed that the extubation practices vary widely among anaesthesiologists. Almost half of the anaesthesiologists were unaware of extubation guidelines.
