Nerve block may ease debilitating headaches after childbirth epidurals
NCT ID NCT04515901
First seen Jul 07, 2026 · Last updated Jul 08, 2026 · Updated 1 time
Summary
This study tests whether a sphenopalatine ganglion block (SPGB) using lidocaine can reduce the severity and duration of post-dural puncture headache (PDPH) in new mothers. PDPH is a severe headache that can occur after an epidural or spinal needle insertion for labor pain relief. The study compares early SPGB (with an option for self-administered repeat blocks) to standard conservative care, aiming to see if a larger trial is feasible.
