NCT05215691

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Cognitive functions

    Cognitive functions will be evaluated with Mini-mental test in each patient on postoperative day 3.

    postoperative day 3

Secondary Outcomes (2)

  • postoperative pain scores

    24 hours postoperatively

  • Postoperative morphine consumption within 24 hours postoperatively

    24 hours postoperatively

Study Arms (2)

Group I (n=45, TAPA)

The patients who received TAPA block for postoperative analgesia are named as a Group I ( n=45). The TAPA block is performed at the rib margin where the 9th and 10th ribs meet. A linear transducer is placed at the costochondral angle in the sagittal plane. It is carried out by injecting 20 ml of Bupivacaine %0.200 between the upper and lower surface of the chondrium. All patients receive IV PCA with morphine 0.5 mg/ml.

Procedure: Group I: TAPA block

Group II (n=45, IV opioid)

The patients who did not prefer the block and preferred intravenous patient-controlled analgesia (PCA) are named as Group II (n=45). IV PCA is prepared with morphine 0.5 mg/ml.

Procedure: Group II: IV Morphine

Interventions

Postoperative analgesia will be provided with peripheral nerve block (TAPA)

Also known as: thoracoabdominal block perichondral appearance
Group I (n=45, TAPA)

Postoperative analgesia will be provided with opioids

Also known as: intravenous morphine group
Group II (n=45, IV opioid)
