All India Difficult Airway Association guidelines in practice—A survey

Abstract

Background and Aims: The All India Difficult Airway Association (AIDAA) has come up with difficult airway (DA) guidelines to suit the Indian context. We conducted an online survey with the primary aim to find out the awareness about AIDAA guidelines and adherence to them in clinical practice. The secondary aims were to explore variations in practice with respect to experience or the type of the institute. Methods: An online web-based questionnaire survey was sent to all practising anaesthesiologists who attended an airway workshop. The validated and piloted questionnaire consisted of 23 questions and the practice patterns were asked to be graded on a Likert scale of four. Results: The response rate was 66%. Awareness about AIDAA guidelines was high (81%) but adherence varied. Apnoeic nasal oxygen insufflation was always practised by only 19.59%.Only 79.7%of the respondents always used capnography to confirm intubation. While 23.64% did not ensure a safe peripheral oxygen saturation (SpO2) level of 95% to do repeat laryngoscopy, 64% chose supraglottic devices after three failed laryngoscopic attempts. A departmental debriefing of a DA event and issuing an alert card to the patient was practised by 58.78% and 52.7%, respectively. Although 50% had training to do cricothyrotomy, only 41% had ready access to a cricothyrotomy set in their workplace. The use of capnography was more prevalent in private institutions. The survey revealed a safety gap with some recommendations like debriefing of a DA event, alert card, nasal oxygenation etc. Conclusion: Awareness about AIDAA guidelines is high among our practising anaesthesiologists, but adherence to the recommendations varied and there is room for improvement, especially for debriefing a DA event, issuing an alert card, the use of capnography and nasal oxygenation.
