ONSD, optic nerve sheath diameter; SBP, systolic blood pressure; DBP, diastolic blood pressure; MAP, mean arterial pressure; SD, standard deviation; T1, 10 minutes after intubation; T2, upon assuming the steep Trendelenburg position after docking; T3, 1 hour postdocking; T4, upon reperfusion; T5, after transition to the supine position; T6, 3 hours postextubation.
a)Repeated measures analysis of variance; b)Post hoc Bonferroni correction.
P<0.05 indicates statistical significance.
