About this trial
The goal of this clinical trial is to investigate the analgesic efficacy of ultrasound-guided Romboid Intercostal and Subserratus (RISS) block versus lower thoracic Erector Spinae Plane (ESP) block after laparoscopic abdominal surgery. The main questions it aims to answer are:
Does ultrasound-guided Romboid Intercostal and Subserratus (RISS) block is effective as the lower thoracic Erector Spinae Plane (ESP) block for intra and postoperative analgesia after laparoscopic abdominal surgery for the first 24 hours? What complications do participants have when doing these interventions?
Researchers will compare the analgesic efficacy of ultrasound-guided Romboid Intercostal and Subserratus (RISS) block with the lower thoracic Erector Spinae Plane (ESP) block after laparoscopic abdominal surgery.
Participants will:
Start general anesthesia and be given either block according to the randomization chart.
The blood pressure and heart rate will be measured at intervals to determine if the participants need extra intraoperative analgesics.
Numerical Rating Scale (NRS) will be used postoperatively to test pain severity.
Rescue morphine analgesia will be measured and compared in both groups.
Any complications will be reported.
Patient and surgeon satisfaction will be measured.
