title: [Central hemodynamics of dogs in the early postresuscitation period and the outcome of resuscitation].
abstract: Variations in central hemodynamics of dogs were compared with the outcome of resuscitation of 18 dogs subjected to 12-minute reversible circulatory arrest because of ventricular fibrillation. Nine survived dogs with completely recovered neurological status during the first 10 minutes after resuscitation had moderate hypertension, the mean arterial pressure (MAP) being 175.0 + 8.9 mm Hg. In the dogs who died within 24-48 hours after resuscitation, the MAP did not rise during this period as compared to the initial level; 2 dogs developed excessive hypertension (MAP about 200 mm Hg). There were also found certain differences in other parameters of central hemodynamics. Moderate hypertension in the first 10 minutes of the postresuscitation period leads to rapid restoration of the adequate level of peripheral blood flow in organs and tissues, thus favouring survival of animals subjected to a long circulatory arrest.
