The aim of our study is to investigate the relationship between intraoperative ETCO2 levels and postoperative nausea-vomiting and pain scores in patients undergoing robotic laparoscopic radical prostatectomy. The investigators will monitor patients' 24-hour postoperative pain, nausea-vomiting and the consumption of additional analgesic and antiemetic medications.

Robotic surgery provides several advantages in the field of surgery, including a three-dimensional view of the surgical site, the elimination of surgeon hand tremors, and enhanced precision in movements. Additionally, it offers benefits such as reduced intraoperative bleeding, faster return to daily functions for patients, and decreased hospitalization duration. Consequently, the use of robots in various surgical procedures has become widespread in contemporary medical practice.

Robot-assisted laparoscopic radical prostatectomy is a surgical technique performed in a head-down Trendelenburg position with intraperitoneal insufflation of carbon dioxide (CO2). This positioning and pneumoperitoneum lead to an increase in intraabdominal pressure, as well as elevated intracranial and intraocular pressures.

End-tidal carbon dioxide (ETCO2) levels can vary during laparoscopic surgery. An increase in ETCO2 levels has been reported to cause an elevation in intracranial pressure, leading to an increased incidence of postoperative nausea and vomiting. Some studies in the literature have investigated the relationship between ETCO2 values and the incidence of postoperative nausea and vomiting in patients. Furthermore, it is believed that hypercarbia (elevated carbon dioxide levels) may have an impact on postoperative pain.

The aim of our study is to investigate the relationship between intraoperative ETCO2 levels and postoperative nausea, vomiting, and pain scores in patients undergoing robotic laparoscopic radical prostatectomy. The investigators will monitor patients' 24-hour postoperative pain, nausea, vomiting, and the consumption of additional analgesic and antiemetic medications.

Robotic prostate surgery is a procedure performed on male patients.

The aim of our study is to investigate the relationship between intraoperative ETCO2 levels and postoperative nausea, vomiting, and pain scores in patients undergoing robotic laparoscopic radical prostatectomy. We will monitor patients' 24-hour postoperative pain, nausea, vomiting, and the consumption of additional analgesic and antiemetic medications.
