				        	Objective  To evaluate the effect of desflurane on blood flow velocity in the middle cerebral artery (VmMCA) and cerebrospinal fluid pressure (CSFP).Methods  Sixty patients were randomly assigned to two groups. In group A,the anesthesia was maintained with desflurane, and in group B, with isoflurane. In either group, patients were  allocated to three subgroups according to different doses(05,08,1.1MAC). CSFP was measured through a lumbar subarachnoid catheter before surgical procedures,from induction to administration of the inhalational agent for 45min.VmMCA was measured by transcranial Doppler  at baseline , postintubation  and   administration of agent for 45min. Results  As compared with baseline,CSFP increased gradually and reached to 16.90?4.01mmHg in subgroup 1.1MAC of group A (P0.05). Compared with baseline, VmMCA increased significantly at 45th  min following administration of agent in subgroup 11MAC of group A(P005). In group A , a significant parallel correlation existed between the MAC levels and  the values of VmMCA or CSFP (r=0.52,P
