Desflurane, a new volatile anesthetic, produces cerebral vasodilation. The purpose of this study was to compare the effects of 1 MAC desflurane with those of isoflurane on cerebrospinal fluid pressure (CSFP) in patients with supratentorial mass lesions and a mass effect on computerized tomography (CT scan). Twenty adult patients undergoing craniotomy for(More)

Transfusion-associated AIDS, hemolytic reactions, TRALI, and anaphylaxis are severe problems that occur relatively rarely, while febrile reactions and mild allergic reactions are common but not serious. The key to avoiding all these complications is autotransfusion (see(More)
