NCT05822479

Brief Summary

In obese patients, adequate pain relief in the postoperative period is an important parameter that affects patient comfort and hospital stay. Increasing patient comfort and recovery quality can be achieved by avoiding undesirable effects such as nausea, vomiting, and analgesia. This study aimed to evaluate the impact of the external oblique intercostal block postoperative acute pain scores and opioid consumption in the first 24 hours after laparoscopic sleeve gastrectomy surgery.

Outcome Measures

Primary Outcomes (1)

  • Cumulative opioid consumption in the first 24 hours after surgery

    Cumulative opioid consumption in the first 24 hours after surgery will be measured. Patients can request opioids via a PCA device when their NRS score is ≥4. In cases where rescue analgesia is required (NRS score ≥4), 25 mg IV meperidine was administered in the recovery unit, and 50 mg IM meperidine was administered in the ward.

    postoperative day 1

Secondary Outcomes (10)

  • Cumulative opioid consumption in the first 12 hours after surgery

    postoperative day 1

  • Postoperative pain scores

    postoperative day 1

  • Patients' satisfaction and quality of pain management

    postoperative day 1

  • The scores of postoperative nausea and vomiting (PONV) and the number of patients requiring postoperative antiemetics.

    postoperative day 1

  • The number of patients who required rescue analgesia.

    postoperative day 1

  • +5 more secondary outcomes

Study Arms (2)

Group EOIB

ACTIVE COMPARATOR

A bilateral EOIB (60 ml, %0.25 bupivacaine, totally) + IV morphine patient-controlled analgesia (PCA)

Procedure: Bilateral ultrasound guided external oblique intercostal block (EOIB)

Group Control

OTHER

IV morphine PCA

Other: Control

Interventions

Bilateral ultrasound-guided EOIB (total of 60 ml, %0.25 bupivacaine) will be performed + IV morphine PCA Multimodal analgesia : Patients are administered iv tenoxicam 20mg and tramadol 100 mg after induction of general anesthesia, iv paracetamol 1 gr and iv morphine 0.05 mg/kg/ideal body weight (IBW) will be administered. Postoperative analgesia: iv paracetamol 1gr every 8 hours and IV PCA of 0,5mg/ml morphine (the bolus dose is 20 µg/kg, the lock-in time of 10 minutes, the 4-hour limit is adjusted to be 80% of the calculated total amount). Rescue analgesia, when necessary (if the resting NRS score is ≥4 despite PCA demand), 25 mg IV meperidine was administered in the recovery unit, and 50 mg intramuscular (IM) meperidine was administered in the ward.

Also known as: External oblique intercostal block
Group EOIB
ControlOTHER

Patients in this group will not be performed interfacial plane blocks. Multimodal analgesia : Patients are administered iv tenoxicam 20mg and tramadol 100 mg after induction of general anesthesia, iv paracetamol 1 gr and iv morphine 0.05 mg/kg/ideal body weight (IBW) will be administered. Postoperative analgesia: iv paracetamol 1gr every 8 hours and IV PCA of 0,5mg/ml morphine (the bolus dose is 20 µg/kg, the lock-in time of 10 minutes, the 4-hour limit is adjusted to be 80% of the calculated total amount). Rescue analgesia, when necessary (if the resting NRS score is ≥4 despite PCA demand), 25 mg IV meperidine was administered in the recovery unit, and 50 mg IM meperidine was administered in the ward.

Masking Details
Sealed opaque envelopes containing study participation numbers will be used to assign each patient. A researcher not involved in patient follow-up will use the web-based "Research Randomizer" (Urbaniak and Plous 2013) tool to give each participation number to a random group with a 1:1 ratio. A nurse not an active investigator in the study will have each participant choose an envelope containing the study participation number. They will inform the anesthetist administering the block/blocks about which group the patient is in immediately before administration. Researchers, surgeons, and nurses will not be aware of the randomization of groups.

Intervention Model

Model Details: A block randomization list will be created by a doctor who does not participate in patient follow-up using a web-based program, 'Research Randomizer (Urbaniak and Plous, 2013)'.
