Pneumoperitoneum Duration and Bicarbonate Changes in Laparoscopic Hernia Surgery

The goal of this observational study is to learn how the length of pneumoperitoneum during laparoscopic inguinal hernia surgery may affect changes in blood bicarbonate levels. Pneumoperitoneum is the use of carbon dioxide gas to create space inside the abdomen during laparoscopic surgery. The main question this study aims to answer is whether a longer pneumoperitoneum time is associated with changes in blood bicarbonate levels after surgery. Participants are adults undergoing laparoscopic inguinal hernia repair as part of their routine medical care. Researchers will measure blood gas values, including bicarbonate levels, before surgery and again two hours after surgery. The change in bicarbonate levels will be compared with the duration of pneumoperitoneum during the operation. The results of this study may help improve the understanding of metabolic changes that occur during laparoscopic surgery.
