Percutaneous cricothyroidotomy may be a lifesaving procedure for airway obstruction, which cannot be relieved by endotracheal intubation and can be performed with specially designed instruments. A new device, the "Quicktrach", was evaluated by an anatomical preparation, flow and resistance measurements, and puncture of the cricothyroid membrane in 55 corpses. The size of the parts of the instrument (needle, plastic cannula, depth gauge) in relation to the size of the larynx is adequate, thus there is little likelihood of perforation of the posterior wall of the larynx. Resistance of the plastic cannula is sufficiently low to allow for adequate ventilation. The duration of time until the cannula is positioned properly in the trachea is significantly shorter, when an incision prior to the puncture is done (83 +/- 88 seconds without incision versus 35 +/- 41 seconds with incision; mean +/- SD). The "Quicktrach" is easy to apply even by inexperienced persons. The incidence of damage to the larynx (lesions including fractures of the thyroid, cricoid and 1. tracheal cartilage in 18%; soft tissue injury in 9%) is relatively high, however considering the live saving character of the procedure these numbers appear to be acceptable. Technical problems which occur with the use of the device are discussed and suggestions for improvement are made.
