BackgroundSafety strategies in civil aviation are well-established. The authors present a possible structure for induction of anesthesia, which includes elements of the so-called cockpit strategy. The objective is to reduce anesthesia-related mortality caused by the unexpected difficult airway through early detection and solution of cannot intubate cannot oxygenate (CICO) situations.MethodsAfter approval by the responsible ethics committee, a prospective pilot study was conducted to analyze the process quality of uncomplicated induction of anesthesia on a simulator using audiovisual recording. An evaluation list with 44 items was created, which met the following requirements: items were dichotomous, accessible to an audiovisual evaluation and according to current scientific consensus should be considered during induction of anesthesia. Standard induction of anesthesia was supplemented by several crew resource management elements (cockpit strategy). Two canned decisions (CD, CD 1: end tidal CO2, etCO2 < 10 mm Hg, CD 2: SpO2 < 80%) signaled the emergency of an unexpected difficult airway and CICO with emergency coniotomy. This concept was repetitively trained and transferred to the daily routine. After 6 months the process quality was re-evaluated in simulated scenarios. In order to review whether the effect of the cockpit strategy with the CD can contribute to solving the CICO situation, all emergency coniotomies carried out in this clinic between 2010 and 2016 were retrospectively analyzed.ResultsThe cockpit strategy significantly improved the process quality during the simulated induction of anesthesia (78% vs. 36% items fulfilled), while the duration of induction was reduced by 36%. In the subsequent 6‑year study period, 7 CICO situations with emergency coniotomy occurred. All teams performed in accordance with the algorithm and with respect to the CDs. No patient suffered from hypoxia or any other damage.ConclusionThe transfer and implementation of a cockpit strategy in anesthesiology for improvement of patient safety is possible. The acceptance of the aviation safety strategy in medicine is a necessary prerequisite. A profound training in technical and non-technical skills and regular team training to solve CICO situations must be an integral part of advanced training in anesthesiology.
