The Correlation Between Intraoperative End Tidal Carbon Dioxide, Perfusion Index and Pulse Variability Index on Postoperative Nausea Vomiting and Pain

Artificial pneumoperitoneum created by the Trendelenburg position and carbon dioxide (CO2) insufflation, which is widely used in laparoscopic procedures, frequently leads to physiological changes such as postoperative nausea and vomiting (PONV) and pain. Therefore, the currently limited usable parameters PI and PVI will be evaluated in correlation with end tidal CO2 in continuous monitoring.
