Sphenopalatine Ganglion Block for Post-Dural Puncture Headache

NCT07494383 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 26

No results posted yet for this study

Summary

This pilot randomised controlled trial compared sphenopalatine ganglion block (SPGB) using intranasal 2% lidocaine versus conservative management (bed rest and aggressive hydration) in patients who developed post-dural puncture headache (PDPH) following accidental dural puncture with 17G Tuohy needles during epidural procedures. The primary outcomes were feasibility metrics (recruitment, retention, and protocol adherence). Secondary outcomes included pain intensity measured by the Numerical Rating Scale (NRS 0-10) at 30 minutes, 12 hours, and 24 hours post-intervention; rescue analgesia requirements; mobilisation time; and adverse events.

Conditions

Interventions

PROCEDURE

Sphenopalatine ganglion block

Bilateral transnasal sphenopalatine ganglion block using cotton-tipped applicators saturated with 2 mL of 2% lidocaine (total 4 mL), applied for 15-20 minutes. Patient positioned supine with slight cervical extension during the procedure.

OTHER

Conservative management

Strict bed rest (supine then prone positioning) with bathroom privileges at bedside only, combined with aggressive intravenous and oral hydration (IV 0.9% saline at 125 mL/hr plus a minimum of 3L oral fluids per 24 hours).
