Sphenopalatine Ganglion Block for the Treatment of Postdural Puncture Headache: A Randomized, Blinded, Clinical Trial. Issue 1 (24th March 2021) - Jespersen, M.S.
Abstract : ( Br J Anaesth . 2020;124:739–747) The epidural blood patch (EBP) has ∼75% success rate in the management of postdural puncture headache (PDPH). EBP is an invasive, painful, and resource-demanding treatment associated with a number of complications. There is evidence to suggest a topical sphenopalatine ganglion block (SPG) could be as effective as EBP at managing PDPH. This randomized blinded study aimed to investigate the effects of SPG block on pain scores and rescue procedures compared with placebo on adult patients with PDPH, fulfilling the criteria for EBP.
