  1. Data are presented as mean ± standard deviation. T1 = 10 min after anesthetic induction in the supine position, T2 = 5 min after establishing carbon dioxide pneumoperitoneum and a steep Trendelenburg position, T3 = 30 min after establishing carbon dioxide pneumoperitoneum and a steep Trendelenburg position, T4 = 60 min after establishing carbon dioxide pneumoperitoneum and a steep Trendelenburg position, T5 = at the end of surgery after desufflation of pneumoperitoneum in the supine position
