Randomized Controlled Trial
Sphenopalatine ganglion block for the treatment of postdural puncture headache: a randomised, blinded, clinical trial.
Current treatment of postdural puncture headache includes epidural blood patch (EBP), which is invasive and may result in rare but severe complications. Sphenopalatine ganglion block is suggested as a simple, minimally invasive treatment for postdural puncture headache. We aimed to investigate the analgesic effect of a transnasal sphenopalatine ganglion block with local anaesthetic vs saline. ⋯ NCT03652714.
