Brief Summary

Laparoscopic cholecystectomy, while less painful compared to conventional methods, is still a surgery that can cause significant pain for patients. Preventing postoperative pain is crucial for reducing respiratory complications, shortening hospital stays, and increasing patient satisfaction. Interfascial plane blocks have been widely used for postoperative analgesia in recent years worldwide. The External Oblique Intercostal Plane Block is one of the interfascial plane blocks used in abdominal surgeries. In our study, we aimed to compare the postoperative pain scores of patients who underwent laparoscopic cholecystectomy under general anesthesia, specifically between those who received the external oblique intercostal plane block and those who had trocar entry site infiltration.

Outcome Measures

Primary Outcomes (1)

  • NRS (Numeric Rating Skore)

    The primary outcome variable is Numerical Rating Scale scores both at rest and motion. A blinded anesthesiologist will assess postoperative pain during rest and motion at the postoperative 15th,30th and 60th minute, second,6th, 12th and 24th hour by using 11-point Numerical Rating Scale which ranges from '0' (means no pain) to '10' (means worst pain imaginable).

    Postoperative 24 hours

Secondary Outcomes (5)

  • Opioid Consumption

    Postoperative 24 hours

  • Time to first rescue analgesic

    Postoperative 24 hours

  • Adverse Events

    Postoperative 24 hours

  • Metoclopromide Consumption

    Postoperative 24 hours

  • Quality of recovery levels between groups by using QoR-15 questionnaire

    Postoperative 24 hours

Study Arms (2)

Grup E (External Oblique Intercostal Plane Block)

ACTIVE COMPARATOR

At the end of the surgical procedure,a high-frequency linear probe will be sterilely covered,and an 80mm block needle will be used for the procedure.Under sterile conditions,the ultrasound probe will be placed in a parasagittal position in the area between the anterior axillary line and the midclavicular line at the level of the 10th rib, and then slid cranially along the longitudinal axis to the level of the 6th and 7th ribs. After visualizing the external oblique muscle, the block needle will be inserted using an in-plane technique,and 5ml of saline will be administered to confirm the location at the external oblique intercostal plane between the external oblique muscle and the 6th rib. Once the location is confirmed, 20cc of 0.25%bupivacaine will be infiltrated into the EOIP. The same procedure will be applied to the opposite side (totally 40 ml).

Device: ultrasound guided external oblique intercostal plane blockDrug: paracetamol, tramadol, and ondansetron

Grup T ( Trocar entry site infiltration)

OTHER

After the trocar removed during the surgical procedure, the surgeon will administer 5 ml of 0.25% bupivacaine infiltration to each trocar entry site.

Drug: Bupivacaine injectionDrug: paracetamol, tramadol, and ondansetron

Interventions

ultrasound guided external oblique intercostal plane block

Grup E (External Oblique Intercostal Plane Block)

5 ml local anesthetic for each trocar sides

Also known as: Local anesthetic injection
Grup T ( Trocar entry site infiltration)

As standard multimodal analgesia, 20 min before the end of the surgery patients will receive 1 g of paracetamol, 1-2 mg/kg of tramadol, and 4 mg of ondansetron via intravenous infusion. All patients will be recovered in the PACU, and after confirming an Aldrete score of \>9, a PCA (patient-controlled analgesia) device will be installed with morphine prepared at a dose appropriate for the patient's age. Patients will be administered paracetamol 1 gr IV every 8 hours in the postoperative period. When patients have a Numerical Rating Scale (NRS) score is ≥ 4, 1 mg/kg iv tramadol will be administered as a rescue analgesic
