Overview
Although laparoscopic techniques are considered minimally invasive surgical procedures with lower perioperative pain scores compared to open surgeries, they are still associated with significant levels of pain. This study aims to investigate the analgesic effectiveness of two routinely performed regional analgesic techniques in our clinic-ultrasound-guided classic bilateral TAP block and ultrasound-guided bilateral M-TAPA block-in patients undergoing laparoscopic gyneco-oncologic surgery (LGOS), as well as their effects on intraoperative opioid consumption.
Interventions
- Procedure TAP Block Group
Patients in the TAP group will receive a bilateral Transversus Abdominis Plane (TAP) block under ultrasound guidance prior to surgery after general anaesthesia, with the local anesthetic administered between the internal oblique and transversus abdominis muscles. A total of 40 mL of 0.25% bupivacaine will be used for the procedure. - Procedure M-TAPA Block group
Patients in the M-TAPA group will receive a bilateral Thoracoabdominal Nerve Block through Perichondrial Approach (M-TAPA) under ultrasound guidance prior to surgery after general anaesthesia. A total of 40 mL of 0.25% bupivacaine will be used for the procedure.
Primary outcome measures
- Evaluation of intraoperative opioid consumption [Time frame: during surgery]
Secondary outcome measures (1)
- Comparison of postoperative Visual Analog Scale (VAS) pain scores [Time frame: postoperative first day]
