Official title: Effect of Intravenous Dexamethasone on The Duration of Hyperbaric Bupivacaine Spinal Anesthesia in Lower Abdominal Surgery-Quasi Experimental Study
Run by Holy Family Hospital, Pakistan · NCT07819682 · Data updated 2026-11-12
This study tests whether giving dexamethasone before spinal anesthesia can lengthen how long the numbness lasts for adults having lower abdominal surgery.

Is this trial a fit for you?
✓Likely a good fit
Adults undergoing lower abdominal or related orthopedic surgeries, ASA I-II, without contraindications to spinal anesthesia or dexamethasone.
✕Probably not a fit
Patients not showing a longer block duration or experiencing no difference between groups may not benefit.

What this trial studies
This is a phase 4, interventional study comparing intravenous dexamethasone to placebo in adults undergoing lower abdominal surgery with spinal anesthesia. Participants with ASA I-II are randomized to receive 8 mg dexamethasone in saline or saline alone before spinal anesthesia with hyperbaric bupivacaine. A standard spinal technique using a 25-gauge needle and 12–15 mg of 0.75% hyperbaric bupivacaine will be used, and blocks will be monitored with sensory and motor assessments to determine duration. Blinding of personnel assessing block duration is maintained. The trial aims to determine if systemic dexamethasone extends the duration of neuraxial anesthesia for improved perioperative management.
Why it matters
Potential benefit: If successful, patients may experience longer sensory and motor block duration, potentially improving analgesia planning and operative conditions.
How similar studies have gone: Previous studies in various settings have shown mixed results for dexamethasone’s effect on neuraxial anesthesia duration; this study adds contemporary data in a specific patient group.
