Research advances of sphenopalatine ganglion block for treatment of post-dural puncture headache
Post-dural puncture headache(PDPH)is a common complication after epidural anesthesia,which refers to the low cranial pressure headache caused by the puncture of the dura puncture.In the past,epidural blood patch(EBP)was often used for treat-ment,but due to its potential complications,the acceptance rate of patients was not high.In recent years,studies have proved that a new,simple,and minimally invasive operation--sphenopalatine ganglion(SPG)block can effectively relieve PDPH.This review summa-rizes the anatomy,development history,mechanism,and operation of SPG block in PDPH treatment to provide a reference for SPG block treatment of PDPH application.
