Hemodynamic data at different time points.

Data are presented as mean ± SD. T0, after anesthetic induction in supine position; T1, 3 minutes after the steep Trendelenburg position (35°) was added to pneumoperitoneum during which time insufflation pressure was set to 15 mmHg; T2, 3 minutes after 500 ml of colloid infusion in T1; SV-Vigileo, stroke volume derived by the FloTrac/Vigileo system; SV-TEE, stroke volume measured using transesophageal echocardiography; MABP, mean arterial blood pressure; HR, heart rate; TSVR, total systemic vascular resistance; AC, arterial compliance.

*P < 0.05 vs T0;

P < 0.05 vs T1.
