Different Insufflation Flows and Effects on Cerebral Oxygenation in Laparoscopic Cholecystectomy

Pneumoperitoneum Clinical Trial

Official title:
The Effects of Hemodynamic Changes on Cerebral Oxygenation Caused by Pneumoperitoneum With Different Insufflation Flows in Laparoscopic Cholecystectomy

Clinical Trial Summary

Previous studies conducted on the hemodynamic effects of pneumoperitoneum pressures created by different insufflation flows are very limited in the literature. In a current literature review, there was no study found comparing the effects of hemodynamic changes created by low and high insufflation flows and pneumoperitoneum pressure on cerebral oxygenation. The purpose of the study was to contribute to the literature by investigating the effects of pneumoperitoneum pressures created by different flows on brain oxygenation.

Clinical Trial Description

After the approval of the Ethics Committee, a total of 69 (sixty-nine) patients who would undergo elective laparoscopic cholecystectomy were planned as ASA I-III, 18-65 years old, 34 (thirty-four) patients low insufflation flow (10 lt/min) and 35 (thirty-five) patients and high insufflation flow (40 lt/min) with pneumoperitoneum pressure. The study will be conducted as a single-center observational study in Trabzon KTU Faculty of Medicine General Surgery Operating Room. Anesthesia always be performed by the same anesthesia team, and no intervention will be made regarding the choice of the method. The data obtained will be recorded by the anesthetists other than the team who constitute the study group, and the data obtained at the end of the surgery will be interpreted by the study team. The decision for laparoscopic cholecystectomy of the patients who will be included in the study will be made by the General Surgery doctor, and the patients who are scheduled to be operated on electively will be included in the study. The patients will be taken to the operating room after their written consents are obtained and preoperative evaluations are made, and routine premedication will be applied to the patients who arrive at the operating room. The patients who will be included in the study will be monitored routinely in the general surgery room (i.e. electrocardiography (ECG), non-invasive blood pressure measurement, peripheral oxygen saturation, Bispectral Index (BIS), and additionally NIRS monitoring. No interference will be made regarding the groups in which patients who will undergo general anesthesia will be in the pneumoperitoneum group formed with low insufflation flow or high insufflation flow, only non-invasive cerebral oxygenation measurements will be made with NIRS monitor (INVOS™ 5100C Cerebral/Somatic Oximeter, SOMANETICS, COVIDIEN, Mansfield/ USA) ;
