Erector Spinae Plane Block in Laparoscopic Colorectal Cancer Surgery: Effects on Renal Blood Flow and Kidney Function
Our study will compare patients who underwent laparoscopic surgery for colorectal cancer with and without Erector Spinae Plane Block in terms of renal blood flow and renal function tests. In our study, which will be conducted by dividing patients into two groups, the investigators aim to demonstrate the effects of the erector spinae plane block on renal physiology by simultaneously monitoring renal blood flow during the intraoperative period using near-infrared spectroscopy and monitoring renal function in the postoperative period using NGAL, serum creatinine, and eGFR.
