Abstract
Cerebral blood flow (CBF) and cardiac output (CO) were measured during cardiopulmonary resuscitation in patients who were unsuccessfully resuscitated by use of C14-iodoantipyrine injected into the left ventricle. CO varied between 1.3 and 2.2 l/min with mean 1.8 +/- 0.6 l/min (+/- SD) (28 ml/kg/min). The cortical CBF was found between 14 and 211 ml 100 g-1.min-1 with mean 42 ml 100 g-1.min-1 and mean white matter CBF equal to 27 ml 100 g-1.min-1. It is suggested that the external cardiac massage in humans may be of poor efficacy in terms of brain revival. Cortical CBF after long-lasting cardiopulmonary resuscitation showed signs of maldistribution suggestive of a patchy and incomplete perfusion.
