Current practice of German anesthesiologists in airway management : Results of a national online survey.

BACKGROUND

There is a worldwide consensus among experts that guidelines and algorithms on airway management contribute to improved patient safety in anesthesia. The present study aimed to determine the current practice of airway management of German anesthesiologists and assess the safety gap, defined as the difference between observed and recommended practice, amongst these practitioners.

OBJECTIVE

To determine the effect of implementing the guidelines on airway management practice in Germany amongst anesthesiologists and identify potential safety gaps.

METHODS

A survey was conducted in September 2019 by contacting all registered members of the German Society of Anaesthesiology and Intensive Care Medicine (DGAI) via email. The participants were asked about their personal and institutional background, adherence to recommendations of the current German S1 guidelines and availability of airway devices.

RESULTS

A total of 1862 DGAI members completed the questionnaire (response rate 17%). The main outcome was that anesthesiologists mostly adhered to the guidelines, yet certain recommendations, particularly pertaining to specifics of preoxygenation and training, showed a safety gap. More than 90% of participants had a video laryngoscope and half had performed more than 25 awake intubations using a flexible endoscope; however, only 81% had a video laryngoscope with a hyperangulated blade. An estimated 16% of all intubations were performed with a video laryngoscope, and 1 in 4 participants had performed awake intubation with it. Nearly all participants had cared for patients with suspected difficult airways. Half of the participants had already faced a "cannot intubate, cannot oxygenate" (CICO) situation and one in five had to perform an emergency front of neck access (eFONA) at least once. In this case, almost two thirds used puncture-based techniques and one third scalpel-based techniques.

CONCLUSION

Current practice of airway management showed overall adherence to the current German guidelines on airway management, yet certain areas need to be improved.
