Fig. 5. The incidences of hypotension (mean arterial pressure of less than 50 mmHg), jugular venous oxygen desaturation (less than 50%), and cerebral oxygen desaturation (more than 20% decrease from baseline) after moving to the beach chair position in patients under sevoflurane-nitrous oxide or propofol-remifentanil anesthesia. *P < 0.05 between groups. MAP = mean arterial pressure; NS = nonsignificant; P/R = propofol-remifentanil anesthesia; S/N = sevoflurane-nitrous oxide anesthesia; SctO2= cerebral tissue oxygen saturation; SjvO2= jugular venous oxygen saturation.
