[Hemodynamic effects of genu-pectoral position during the surgery of lumbar disk herniation: spinal anesthesia versus general anesthesia].

Spinal anesthesia (SA) for lumbar disk surgery in the genu-pectoral position (GP) has been proposed as an alternative to general anesthesia (GA). This study compares the haemodynamic effects of GP in two groups of patients undergoing either SA (n = 43) or GA (n = 40). Mean arterial pressure (MAP) and heart rate (HR) were recorded before and after GP.

[Intravascular volume expansion and intravenous nimodipine in the treatment of cerebral vasospasm after surgical treatment of intracranial aneurysm].

The advantage of calcium antagonist on cerebral arterial spasm during the peri-operative period has been recently demonstrated. However, the role of volemia and cardiac output in the pathogenesis of arterial spasm seems predominant. The basal hemodynamic profile of 17 patients operated for an intracranial aneurysm was investigated.
