Dynamics of intracranial pressure (median with 25–75 percentile). In patients with initially normal levels of ICP, this value remained stable at all stages of the study. In the group with initially elevated ICP, it decreased during anesthesia. ICP – intracranial 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 ICP
