Mobile Intensive Care in Myocardial Infarction

Abstract

In the first six months of its existence a mobile intensive care unit was used to admit 95 patients with definite or probable myocardial infarction to the local district hospital. Though the area served was a rural one, with a radius of about 25 miles from the hospital, the average interval between receiving a call and starting intensive care was less than 30 minutes. Five patients with ventricular fibrillation were successfully resuscitated by the mobile team outside hospital. The mobile unit has made it possible to admit many more patients with myocardial infarction to hospital than before, and we believe its cost and use of skilled staff are justified by the results. The unit reduces the delay between the onset of symptoms and initiation of intensive care and thus diminishes the risk of primary ventricular fibrillation, which is maximal soon after the onset of symptoms. Since mobile intensive care removes the risk of transport it allows concentration of cases of acute myocardial infarction in the larger hospitals.
