Prehospital cricothyrotomy in air medical transport: outcome.
In an attempt to determine outcome, this study reviewed the records of air medical patients undergoing prehospital cricothyrotomy (CRIC) from 1987 through 1989. The study included initial airway management, Trauma Score (TS) before and after CRIC and on arrival to the hospital, outcome, and initiator of airway--either emergency medical services (EMS) or LifeFlight air medical crew (LF). There were 68 CRIC in 3285 completed missions (2%). Patients averaged 31.4 years old with 46 males and 22 females. In rural environments, 60/68 patients were injured, with 65/68 injuries by blunt mechanisms. CRIC was performed by EMS in 24/68 patients and by LF in 44/68 patients. TS before CRIC, after CRIC, and on arrival to the hospital was not significantly different, averaging 5.8, 5.8, and 5.2. There were three complications of CRIC: two bleeds and one failure to insert. Five CRIC were changed to another airway at the receiving facility. Twenty-one out of 68 patients survived to discharge. There were no statistically significant differences in complications or overall mortality between LF and EMS CRIC. Prehospital CRIC appeared safe and complications were infrequent. The CRIC, once placed, remained the airway of choice in most patients. The eventual outcome in this population suggested serious injury with the majority of patients (69%) dying.
