Background: Out-of-hospital airway management confronts emergency medical teams with complex challenges. To date no specific data are available on the qualifications of emergency physicians (EPs) and the quality of emergency equipment in northern Germany.
Materials and methods: This study surveyed individual EPs at regional emergency dispatch centres about their personal knowledge and skills, and the procedures and equipment used in out-of-hospital airway management.
Results: A total of 606 EPs from 59 of the 66 (89.4%) regional emergency dispatch centres surveyed responded and 56.1% of the EPs questioned were anesthesiologists. The other EPs were qualified in either internal medicine (22.6%), surgery (12.4%), general medicine (5.6%) or other specialties (3.3%). All (100%) of the EPs trained in anesthesia and 35.2% of the other EPs reported that they had performed more than 100 in-hospital endotracheal intubations (ETI). 93% of all EPs rated out-of-hospital ETI as more difficult than in-hospital ETI. A total of 33.0% of anesthesia-trained EPs and 6.1% of the other EPs used muscle relaxants for ETI in more than 20% of the cases. Of the anesthesia-trained EPs 38.1% used expiratory CO(2) monitoring to verify tube placement compared to 12.1% of the other EPs. A total of 97.8% of anesthesia-trained EPs reported having used an extra-glottic airway device more than 20 times compared to 11.1% of the other EPs. For the emergency equipment 44.4% included an extraglottic airway device, 57.8% a cricothyrotomy set and 27.1% CO(2) monitoring options.
Conclusion: Neither the emergency equipment nor the physicians' knowledge and skills were sufficient to meet the special demands of out-of-hospital airway management, particularly among non-anesthesiologists.
