چکیده

Thirty-five patients undergoing cardiac surgery requiring cardiopulmonary bypass (CPB) were allocated randomly in a prospective double-blind study to receive either nimodipine 0.5 micrograms kg-1 min-1 or placebo. Cerebral blood flow (CBF) was measured during and immediately after CPB. Neuropsychological tests were performed 6 months after surgery to determine any relationship between ischaemic damage and CBF and administration of nimodipine. There were no differences in CBF between the nimodipine (n = 18) and placebo groups (n = 17). Significant changes in neuropsychological tests were found in six patients tested 6 months after surgery but there were no conclusive signs of ischaemic damage. The nimodipine-treated group performed better in tests of verbal fluency and visual retention, suggesting that some memory functions were preserved better in this group.

The effects of a calcium antagonist, nimodipine, upon physiological responses of the cerebral vasculature and its possible influence upon focal cerebral ischaemia.

The effects of a calcium antagonist, nimodipine, were tested on the response of the cerebral circulation to arterial pCO2 and blood pressure changes. The effects of reduced blood flow upon oedema formation and extracellular ion homeostasis under nimodipine preloading were studied. Both open and closed skull primate models were used, with alpha-chloralose anaesthesia. Nimodipine infusion increas...

Continuous-Flow Cell Saver Reduces Cognitive Decline in Elderly Patients After Coronary Bypass Surgery

Background—Cerebral microembolization during cardiopulmonary bypass may lead to cognitive decline after cardiac surgery. Transfusion of the unprocessed shed blood (major source of lipid microparticulates) into the patient during cardiopulmonary bypass is common practice to reduce blood loss and blood transfusion. Processing of shed blood with cell saver before transfusion may limit cerebral mic...

Nimodipine attenuates both increase in cytosolic free calcium and histologic damage following focal cerebral ischemia and reperfusion in cats.

To clarify the mechanism of its effect on ischemic stroke, we investigated the effect of nimodipine, a dihydropyridine calcium antagonist, on changes in cytosolic free calcium, cortical blood flow, and histologic changes following focal cerebral ischemia and reperfusion in 14 cats. Using indo-1, a fluorescent intracellular Ca2+ indicator, we simultaneously measured changes in the Ca2+ signal ra...

Effect of the calcium antagonist nimodipine on local cerebral blood flow: relationship to arterial blood pressure.

The effect of the calcium antagonist nimodipine on local CBF in 31 regions of the CNS was studied with the [14C]iodoantipyrine autoradiographic technique in lightly anaesthetised, mechanically ventilated rats. Continuous intravenous infusion of nimodipine (1, 2, or 4 micrograms kg-1 min-1) produced a dose-dependent reduction in MABP (reduced by 26 +/- 2% after 30 min of nimodipine, 4 micrograms...

Effects of nimodipine on cerebral hemodynamics, and prognosis of diffuse axonal injury patients.

OBJECTIVE To evaluate the effects of nimodipine on hemodynamic state, vasospasm, and short time prognosis of diffuse axonal injury (DAI) patients. METHODS In a prospective, clinical trial double blind study, 40 DAI patients with Glasgow coma scale of 5-8 were selected and randomly divided into 2 equal groups. The first group was treated with 60 mg of nimodipine every 4 hours immediately after...
