Study summary

Objectives: To compare the effectiveness of erector spinae plane block (ESPB) and rectus sheath block (RSB) in providing postoperative analgesia after supraumbilical surgery in adult patients and their impact on the patient's outcomes.

Background: Supraumbilical surgery for hernia repair is the second-most-popular after surgical inguinal hernia repair and is accompanied by moderate to severe postoperative pain, so patients always require large doses of opioids within the first postoperative day. Because opioids have several adverse effects such as drowsiness, pruritus, nausea, and vomiting, regional analgesic techniques are an essential component of postoperative opioid-sparing analgesia. Previous studies have shown that regional analgesic techniques after abdominal wall surgeries can be an essential element of a postoperative pain management strategy with minimal adverse effects and hemodynamic responses.

ESPB provides both somatic and visceral analgesia to the abdominal wall, through the blockade of the anterior rami of spinal nerves and the rami communicants involving sympathetic nerve fibers. RSB provides analgesia to the anterior abdominal wall from the xiphoid process to the symphysis pubis, through the blockade of the anterior rami of the 7th to 12th intercostal nerves. The dermatomal distribution of ESPB and RSB makes them ideal regional analgesic techniques after abdominal surgery, and to our knowledge, there were no previous trials that studied the difference between them.

Patients and Methods: This was a prospective, randomized (1:1), double-blind clinical trial on 60 patients scheduled for elective supraumbilical surgery under general anesthesia at our hospital. Patients will be randomly allocated into two equal groups (30 patients each) and will receive: in group E; general anesthesia with postoperative bilateral ultrasound-guided ESPB, whereas in group R; general anesthesia with postoperative bilateral ultrasound-guided RSB.

Inclusion criteria

  • (ASA) physical status ≤ II
  • Age from 21 to 60 years
  • (BMI) \< 35 kg/m²

Exclusion criteria

Exclusion Criteria:

  • (ASA) physical status > II
  • Age \< 21 years or > 60 years
  • (BMI) ≥ 35
  • Local infection at the puncture site
  • Altered mental status
  • Pregnant women

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

ASA physical status

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

What researchers measure

Primary outcomes

  1. Mean and Standard deviation of time to the first request of postoperative rescue analgesic (minutes) (mean±SD)

    The time interval between the block performance and the first request of postoperative analgesia

    Time frame: 24 hours after block performance

Secondary outcomes

  1. Mean and Standard deviation of Numeric Pain Rating Scale (NPRS) score (mean±SD)

    NPRS measures the severity of postoperative pain, it is a 11 point scale from 0-10; where 0=No pain and 10=Worst possible pain (30 minutes, 1h, 6h, 12h, 18h, 24h) after block performance

    Time frame: 24 hours after block performance

  2. Mean and Standard deviation of the total dose of the rescue analgesic consumed (milligrams) (mean±SD)

    The total dose of the rescue analgesic consumed in the first 24 hours after block performance

    Time frame: 24 hours after block performance

  3. Number of participants and Rate of Postoperative Complications

    Number of participants and Rate of: Nausea, Vomiting, Hematoma formation, Bowel perforation, and Pneumothorax

    Time frame: 24 hours after block performance
