Barbiturate therapy has been employed for reduction of increased intracranial pressure (ICP) after acute brain injury and also for cerebral resuscitation. However, this treatment may be complicated by hypotension with an adverse impact on survival. We, therefore, investigated the acute hemodynamic effects of pentobarbital (PB) when administered in loading doses of 4-7 mg/kg and maintenance doses of 1-4 mg/kg. After pentobarbital therapy, HR, mean arterial pressure (MAP), and rectal temperature were significantly reduced. Four episodes of hypotension and 6 episodes of oliguria were observed during the initial 12 h of therapy in close relationship to reduced cardiac output, stroke volume, and MAP. These abnormalities were corrected by infusion of colloid-containing fluids. We postulate that increases in venous capacitance, hypovolemia, and decreased barostatic reflexes, rather than depression of myocardial function, accounted for the hemodynamic abnormalities.
