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%). ⋯ 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.

To determine the incidence, type, and outcome of protocol deviations in an emergency medical services (EMS) system. ⋯ Protocol deviations committed in prehospital care do not usually cause direct harm to patients. On review of these deviations, however, several disturbing trends were uncovered, including misconceptions in the use of IV therapy, a number of serious deviations in advanced cardiac life support protocols, and lack of communication with medical control. This type of quality assurance study has the ability to identify areas of strength and weakness in an EMS system, allowing planning of ongoing educational efforts in the system.

The optimal dose of epinephrine in human cardiac arrest remains an area of continuing controversy. Apart from animal data some anecdotal reports in humans suggest that the dose currently recommended by the AHA may be insufficient for resuscitation of spontaneous circulation during prolonged cardiac arrest (CA). Since 1982, 1610 CA patients registered in Bruges have been evaluated under the following variables: prolonged survival (class 3 CPCR successes); solely restoration of spontaneous circulation (ROSC): class 2a, 2b and 3); epinephrine dose used during cardiopulmonary resuscitation (CPR); duration of advanced life support (ALS) and duration of complete CA. ⋯ E. M.) for the total population (n = 1724) was 2.53 +/- 0.06 mg; for patients since March 1989 (n = 114) this number was 5.58 +/- 0.36 mg. In contrast to the period before March 1989, we found a non-significant positive correlation between the survival of class 3 and epinephrine dose by limiting the influence of CPR times in the asystole and electromechanical dissociation (EMD) arrest groups.

To determine the characteristics and effects of quality assurance programs in emergency medical service (EMS) systems in Michigan, medical directors of all EMS medical control authorities in Michigan were mailed a survey consisting of 14 closed-ended and open-ended questions including 2 using a subjective continuum scale; the study included phone follow-up of nonrespondents. Twenty-nine (56%) of 52 authorities surveyed responded; 28 reported that they conducted quality assurance activities. ⋯ Although 26 (92%) respondents reported that their quality assurance program made a difference in the quality of care delivered, lack of standards and resources were most frequently listed as program weaknesses. Survey findings prompted the EMS Division of the Department of Public Health, State of Michigan, to address quality assurance in statewide seminars and to develop guidelines for statewide implementation.
