Dexamethasone versus magnesium added to bupivacaine for erector spinae plane block after elective cesarean

Official title: The Efficacy of Dexamethasone Versus Magnesium Sulphate as an Adjuvant to Bupivacaine in Ultrasound Guided Erector Spinae Plane Block for Postoperative Analgesia in Elective Caesarean Section Under Spinal Anesthesia: A Randomized Controlled Trial.

Run by Cairo University · NCT07139522 · Data updated 2026-11-12

This study will test whether adding dexamethasone or magnesium sulfate to bupivacaine in an erector spinae plane block gives better pain relief after elective cesarean under spinal anesthesia.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are full-term, singleton pregnant women aged 18–35 years with ASA physical status II who are scheduled for elective cesarean delivery under spinal anesthesia.

Probably not a fit

Patients having emergency cesarean sections, significant chronic medical conditions, hypertensive disorders of pregnancy, high BMI (≥35), contraindications to spinal anesthesia, or known allergy to the study drugs are unlikely to qualify or benefit.

What this trial studies

Investigators will compare the effects of adding either dexamethasone or magnesium sulfate to bupivacaine for bilateral ultrasound-guided erector spinae plane (ESP) blocks in women having elective cesarean delivery under spinal anesthesia. Participants will receive the ESP block with bupivacaine plus one of the adjuvants and postoperative outcomes such as pain scores, duration of analgesia, and opioid consumption will be recorded. The ESP block is an interfascial paraspinal technique intended to provide both somatic and visceral pain relief for Pfannenstiel incisions. The goal is to identify which adjuvant prolongs and improves postoperative analgesia with acceptable safety.

Why it matters

Potential benefit: If successful, this could give longer and better pain control after cesarean delivery and reduce the need for opioids.

How similar studies have gone: Previous studies commonly report that perineural dexamethasone prolongs local anesthetic effects while magnesium sulfate has shown mixed but sometimes positive results as an analgesic adjuvant.
