Official Title: Comparison of the Effects of 100% and 80% Oxygen Use During Extubation on Oxygen Reserve Index in Laparoscopic Colorectal Surgery

Brief Summary: During laparoscopic procedures, certain physiological changes occur due to the creation of pneumoperitoneum.One such change is the reduction in portal venous blood flow, which can lead to decreased liver perfusion and acute liver cell injury.Additionally, due to an increased alveolar-arterial oxygen pressure gradient, postoperative atelectasis may occur, leading to hypoxia.In other words, the increased intra-abdominal pressure during laparoscopic surgery-along with the effects of patient positioning and mechanical…
