Prehospital surgical airway management: 1 year's experience from the Helicopter Emergency Medical Service.

Advanced Trauma Life Support requires surgical airway techniques to be used in patients when oral or nasal intubation is impossible or contraindicated. Few reports have examined the results of surgical cricothyroidotomy in prehospital trauma management. During a 12-month period, 600 patients were seen and treated by the Helicopter Emergency Medical Service medical team. Advanced airway techniques were performed at the scene in 143 cases (24 per cent). Of these cases, orotracheal intubation was performed in 132 (92.3 per cent) and surgical cricothyroidotomy in 11 (7.7 per cent). The indications for cricothyroidotomy were: (1) failed intubation in patients with facial injuries, (2) intubation impossible due to patient position during entrapment, and (3) severe burns. Four patients, who were already in cardiopulmonary arrest, succumbed in the field despite cricothyroidotomy. Three patient later died in hospital and four (37 per cent) survived. Three of the survivors made a good recovery, including one who was in cardiorespiratory arrest at the scene, and one remains severely disabled. Surgical cricothyroidotomy is a life-saving procedure in prehospital trauma management that must be performed without delay or hesitation if conventional airway manoeuvres are impossible or fail.
