Dp. Archer et al., CARDIAC-PERFORMANCE ENHANCEMENT FOR THE P REVENTION AND TREATMENT OF DELAYED CEREBRAL-ISCHEMIA DUE TO VASOSPASM, Annales francaises d'anesthesie et de reanimation, 15(3), 1996, pp. 359-365
Following subarachnoid haemorrhage, delayed cerebral ischaemia from ce
rebral vasospasm remains the most important cause of mortality and mor
bidity in patients with surgically secured aneurysms. Therapy with hae
modilution, hypertension and volume expansion has been recommended to
prevent and treat delayed cerebral ischaemia in these patients on the
basis of uncontrolled clinical series (level of evidence III to V, gra
de C recommendation). Despite the lack of controlled studies, the main
tenance of a cardiac index > 3.5 L . min(-1).m(-2) and a systolic arte
rial pressure between 120 and 150 mmHg before clipping and 160 to 200
mmHg thereafter is recommended as a prophylactic or therapeutic measur
e for vasospasm. Close monitoring of neurological and cardiorespirator
y status is important to avoid neurologic and systemic complications.
