  1. aData presented as mean ± SD. Control, control group; CO2, group with CO2 pneumoperitoneum; VOL, group with intra-abdominal volume addition by placement of saline bags. Statistics: group-time interactions were analyzed by repeated measures ANOVA. b P value, difference between groups over time. Kruskal-Wallis one-way ANOVA on ranks using Dunn's method for multiple comparisons between groups at corresponding moments, cdifferent from control, CVP, central venous pressure; MPAP, mean pulmonary artery pressure; MAP, mean arterial pressure; APP, abdominal perfusion pressure; Cdyn, dynamic lung compliance.
