Abstract
A 10-minute cardiac arrest was produced in dogs by electrical fibrillation of the
heart. Recovery of cerebral function was monitored by estimating the cerebral metabolic
rate of oxygen consumption (CMRO2), cerebral blood flow (CBF), electroencephalograph (EEG) and extent of neurological
deficit. The study group received flunarizine (0.1 mg/kg intravenously) at the beginning
of resuscitation, while control animals were given the drug vehicle. By four hours
after resuscitation, CMRO2 in flunarizine-treated dogs was 121 ± 43% of pre-arrest baseline, as compared with
37 ± 9% in control animals (P < 0.02). In the flunarizine group, CBF was 83 ± 21% of baseline, while it was only
31 ± 8% in controls (P < 0.01). As compared with the control group, no other significant changes were detected
in electrocardiographic, hemodynamic, or biochemical parameters in the flunarizine-treated
dogs. A significant improvement in the visual EEG score (P < 0.001) and neurological deficit (P < 0.05) was seen in flunarizine-treated dogs six hours after ischemic insult.
