Does intra-arterial nicardipine infusion improve CT perfusion-measured cerebral blood flow in patients with subarachnoid hemorrhage-induced vasospasm?
IA nicardipine improves CBF and MTT in ischemic regions in patients with aSAH-induced vasospasm. Our data provide a tissue-level complement to the favorable effects of IA nicardipine reported on prior angiographic studies. CTP may provide a surrogate marker for monitoring the success of treatment strategies in patients with aSAH-induced vasospasm.
After laparotomy, total sleep time increased and there was a change in diurnal sleep distribution. These sleep alterations were less pronounced after laparoscopic cholecystectomy. Thus, sleep architecture was disturbed for ?4 weeks after major abdominal surgery but for only 1 week after laparoscopic cholecystectomy.
