About

The investigators aimed to show the renal damage caused by increased intra-abdominal pressure in laparoscopic surgeries and to investigate whether its reflection on NIRS would be clinically effective.The main question it aims to answer are:

Does pneumoperitoneum cause renal damage?

NRS monitoring will be performed in patients undergoing laparoscopic surgery. Preoperative and postoperative blood tests will be performed at certain hours. N-GAL, urea and creatinine values will be recorded.

Full description

Renal NIRS monitoring will be performed in patients undergoing laparoscopic cholecystectomy surgery. Age, gender, BMI, ASA scores, hemogblin/hematocrit values, intraoperative hemodynamic parameters, NIRS values, N-GAL (preoperative, 2nd hour and 24th hour), urea/creatinine (preoperative, postoperative 24th hour) values of the patients will be recorded. .

Before the general anesthesia is performed, the renal tissues of the patients will be visualized by ultrasound, the skin-renal cortex distances will be measured, and suitable patients will be included in the study. Basal rSO2 values will be recorded by placing NIRS probes under the 10-11. intercostal space in the bilateral posterior lateral flank region.

Enrollment: 58 estimated patients

Sex: All

Ages: 18 to 85 years old

Volunteers: No Healthy Volunteers

• emergency cases

Trial design

58 participants in 1 patient group

Patients undergoing laparoscopic cholecystectomy.

Description:

Basal rSO2 values will be recorded by placing NIRS probes under the 10-11th intercostal space in the bilateral posterior lateral flank region. Age, gender, BMI, ASA scores, Hb/Htc values, intraoperative hemodynamic parameters, NIRS values, N-GAL (preoperative, 2nd hour and 24th hour), urea/creatinine (preoperative, postoperative 24th hour) values of the patients will be recorded. .
