In 2011 the Hungarian Air Ambulance Nonprofit Limited Company introduced a new Rapid Sequence Intubation standard operating procedure using a template from London’s Air Ambulance. This replaced a previous ad-hoc and unsafe prehospital advanced airway management practice. It was hoped that this would increase clinical standards including internationally comparable results. All Rapid Sequence Intubations performed by the units of the Hungarian Air Ambulance under the new procedure between June 2011 and November 2013 were reviewed in a retrospective database analysis. During this period the air ambulance units completed 4880 missions with 433 intubations performed according to the new procedure. The rate of intubations that were successful on first attempt was 95.4% (413), while intubation was successful overall in 99.1% (429) of the cases; there was no failed airway. 90 complications were noted with 73 (16.9%) patients. Average on scene time was 49 minutes (ranging between: 15–110 minutes). This data shows that it is possible to effectively change a system that was in place for decades by implementing a new robust system that is based on a good template.

The Hungarian Air Ambulance has recently adopted oxygen supplementation during laryngoscopy, also known as apneic preoxygenation, to prevent desaturation during rapid sequence intubation. Despite its simplicity the nasal cannula method has some limitations relevant to our practice. First, the cannula can dislodge if the head is manipulated during preparation or intubation, especially if nasopharyngeal airways are chosen to maximise preoxygenation. Second, the method is incompatible with continuous nasal suctioning required in severe maxillofacial trauma. Third, if only one oxygen source and one competent assistant is available, a situation common during prehospital missions, the extra tube swap needed for continuous oxygen supplementation makes the procedure more complex and prone to error. We report a new method that provides comparable oxygen supplementation to the nasal cannula method, but at the same time eliminates the problems mentioned above and is easier and quicker to perform. It requires the intubator to cut and insert the tubing of the non-rebreather mask into the nasopharyngeal airway, thus providing direct pharyngeal insufflation. The method is applicable to every patient who has at least one nasopharyngeal airway inserted at the time of laryngoscopy and it only requires a pair of scissors.Electronic supplementary materialThe online version of this article (doi:10.1186/s13049-016-0200-0) contains supplementary material, which is available to authorized users.
