Comparison of systemic hemodynamics after subarachnoid administration of either levobupivacaine or ropivacaine to elderly hypertensive patients

This study compares the cardiovascular effects of spinal levobubivacaine or ropivacaine, in equipotent doses, for endoscopic urologic surgery. Eighty elderly, hypertensive patients, with physical status ASA I-III, scheduled to undergo transurethral procedures, were randomly allocated to receive spinal anesthesia with either 15 mg of levobupivacaine or 22.5mg of ropivacaine, in hyperbaric solutions.
