About this study

Background: Paraumbilical hernia repair is a frequently performed surgical procedure, often associated with significant postoperative pain and delayed recovery, which are major concerns for patients.

Objectives: This study aimed to compare the analgesic efficacy of the external oblique intercostal fascial plane block (EOIPB) versus the rectus sheath block (RSB) for managing postoperative pain following paraumbilical hernioplasty.

Methods: This prospective, randomized, single-blinded study enrolled 60 patients, divided into two groups (EOIPB and RSB), each comprising 30 participants. Blocks were administered after general anesthesia and prior to surgery. Patient demographics (age, weight), surgical duration, pain scores (measured by Numeric Rating Scale - NRS), total postoperative morphine consumption, intraoperative fentanyl consumption, and hemodynamic parameters (mean arterial pressure - MAP and heart rate - HR) were assessed.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patients aged 18-65 years, classified as American Society of Anesthesiologists (ASA) physical status I or II [16], and scheduled for elective paraumbilical hernioplasty.

Exclusion criteria

  • Patients with a history of prolonged opioid medication, allergy to local anesthetics, pregnancy, infection at the injection site, and/or coagulopathy.

Treatment and study plan

External Oblique Intercostal Fascial Plane Block for Postoperative Analgesia

Procedure

After the induction of general anesthesia and approximately 15 minutes before the surgical incision, patients were randomly assigned to receive either the EOIPB (Group A) or the RSB (Group B).

Primary outcomes

  1. Total postoperative morphine consumption in milligrams during the first 24 hours after surgery

    Time frame: First 24 hours postoperatively

    Total cumulative morphine requirement administered for postoperative analgesia during the first 24 hours following paraumbilical hernia repair surgery, measured in milligrams (mg).

  2. Number of participants experiencing block-related or postoperative complications within 3 months after surgery

    Time frame: 3 months after surgery

    Assessment of postoperative and block-related complications including local anesthetic toxicity, hematoma, infection, nausea/vomiting, respiratory depression, and other adverse events recorded during the follow-up period.
