Bloqueio esfenopalatino no tratamento de cefaleia pós-raquianestesia em criança: estudo de caso

Abstract

Post-Dural Puncture Headache (PDPH) is a complication associated with spinal anesthesia and lumbar puncture, with variable incidence in the pediatric population. This paper reports the case of a pediatric patient with PDPH refractory to conservative treatment, successfully managed with a transnasal sphenopalatine ganglion block. The procedure resulted in complete symptom resolution without recurrence. Literature review suggests that SPGB is a minimally invasive, safe, and easy-to-perform technique, which may serve as an alternative to the epidural blood patch in selected cases. For anesthesiologists, treating postdural puncture headaches has always been challenging. Despite positive results, robust studies are needed to consolidate its use in pediatrics.
