Erector spinae block to lower opioid use after total abdominal hysterectomy

Opioid Sparing Effect of Erector Spinae Block in Patients Undergoing Total Abdominal Hysterectomy; A Randomized Control Trial

Phase 4 Interventional Kulsoom International Hospital · NCT07178262

What this trial studies

Total abdominal hysterectomy causes substantial postoperative pain and often requires high perioperative opioid doses, which can slow recovery due to nausea, vomiting, constipation, and respiratory depression. In this interventional Phase 4 protocol, participants undergoing elective total abdominal hysterectomy receive either an erector spinae plane (ESP) block with bupivacaine or a placebo block in the perioperative period. Opioid consumption after surgery, along with common opioid-related side effects and recovery measures, will be recorded and compared between groups. Eligible patients are adults classified as ASA I–III having elective procedures at the study hospital.

Who should consider this trial

Good fit: Ideal candidates are adults (ASA class I–III) scheduled for elective total abdominal hysterectomy who can consent and do not have chronic opioid use or other exclusion criteria.

Not a fit: Patients with chronic pain, active opioid misuse or addiction, allergy to local anesthetics, or BMI over 35 are excluded and unlikely to gain benefit from this protocol.

Why it matters

Potential benefit: If successful, the ESP block could reduce perioperative opioid use and related side effects, helping patients recover more comfortably after hysterectomy.

How similar studies have performed: Fascial plane blocks including ESP and related regional techniques have shown reductions in postoperative opioid use in several surgical settings, but evidence is still emerging and varies by procedure.
