Outcomes of Thoracoabdominal Nerve Block Through Perichondrial Approach* on Postoperative Cognitive Functions

It was planned to compare the opioid consumption and cognitive functions in the postoperative period of patients who received TAPA block for postoperative analgesia and patients who did not prefer the block and who preferred intravenous patient-controlled analgesia (PCA) with opioids. Both the surgery applied and the drugs used in anesthesia can cause changes in cognitive functions by affecting the inflammatory process. It is thought that if the patients' pain can be relieved sufficiently in the postoperative period with TAPA block, the consumption of opioids used will be less and their cognitive functions will be less affected.
