Fig. 2From: Safety and efficacy of combined epidural/general anesthesia during major abdominal surgery in patients with increased intracranial pressure: a cohort studyDynamics of cerebral perfusion pressure (median with 25–75 percentile). In both groups, cerebral perfusion pressure decreased, but remained above 60 mm Hg. CPP – cerebral perfusion pressure. Dotted red line – group with normal initial ICP. solid black line - group with elevated initial ICP. p <0.05 compared to patients with normal initial ICPBack to article page
