Interventions

  • Group EOIPB (External Oblique Intercostal Plane Block) — PROCEDURE
    Patients will undergo bilateral EOIPB procedure using 20 ml of 0.20% bupivacaine on each side under ultrasound guidance.
  • Group EOIPB + RIFPB (Combined Blocks) — PROCEDURE
    Patients will undergo bilateral EOIPB and RIFPB procedures under ultrasound guidance using 20 ml of 0.20% bupivacaine for the EOIPB block and 15 ml of 0.20% bupivacaine for the RIFPB on each side.

Study Details

Laparoscopic cholecystectomy is a common surgical procedure that can cause significant postoperative pain, particularly originating from trocar insertion sites. Regional anesthesia techniques are frequently used as part of multimodal analgesia to improve patient comfort. This randomized controlled trial aims to evaluate the efficacy of adding a recto-intercostal fascial plane block (RIFPB) to an external oblique intercostal plane block (EOIPB). Patients scheduled for elective laparoscopic cholecystectomy will be randomly assigned to receive either an EOIPB alone or a combination of EOIPB and RIFPB. The primary objective is to determine if the combined block approach provides superior postoperative analgesia, evaluated by compared to the EOIPB alone.

Arms

  • Active Comparator: Group EOIPB (External Oblique Intercostal Plane Block)
    Patients in this group will undergo ultrasound-guided external oblique intercostal plane block (EOIPB) after general anesthesia and before surgical incision. The block will be performed bilaterally using 20 mL of % 0.20 bupivacaine on each side.
  • Active Comparator: Group EOIPB + RIFPB (Combined Blocks)
    Patients in this group will receive both an ultrasound-guided external oblique intercostal plane block (EOIPB) and a recto-intercostal fascial plane block(RIFPB) after the induction of general anesthesia and prior to surgical incision. The procedures will be performed bilaterally. The EOIPB block will be administered using 20 mL of % 0.20 bupivacaine, and the RIFPB will be administered using 15 mL of % 0.20 bupivacaine on each side.
