Helicopter transport of patients to tertiary care centers after cardiac arrest.
Air transport is commonly used to transfer survivors of cardiac arrest from rural hospitals to large tertiary-care centers, presumably to improve outcome. To examine this issue, a retrospective review of patients stabilized after a cardiac arrest was conducted; 157 transports were reviewed. The mean age of patients was 37.9 +/- 27.8 yrs, with a male to female ratio of 2.2:1. Survivors were significantly older than nonsurvivors. Thirty-one of 69 patients (45%) with primary cardiac disease were discharged alive from the hospital, 75% without neurological sequelae. Only a minority of patients with noncardiac medical illness (7%), electrical injury (33%), suffocation (15%), near-drowning (15%), and inhalation (0%) were discharged alive from the hospital. Outcomes for cardiac arrest in adult patients older than 65 years (32.3% survival) were similar to those for adult patients younger than 65 years (36.2% survival) (P = .887). These results show that survivors of a primary cardiac event have a favorable outcome when transferred by air to tertiary centers when compared with historical controls that were transported by ground. On the other hand, cardiac arrests from noncardiac medical illness, suffocation, near-drowning, and inhalation have a grim prognosis. Prospective studies should clarify the role of air transport in these patients.
