Study summary

The purpose of the study is to compare Sphenopalatine ganglion block (SPGB) and aminophylline in the efficacy and safety management of PDPH.

Read the detailed description

Postdural puncture headache (PDPH) is a severe and debilitating complication after regional anesthesia in the obstetric population; The gold standard treatment for PDPH is epidural blood patch, which is an invasive and risky procedure.

The trans-nasal sphenopalatine ganglion (SPG) block and intravenous aminophylline are promising options for PDPH. So the investigators designed this randomized, double-blind study to compare Sphenopalatine ganglion block (SPGB) and aminophylline in the efficacy and safety management of PDPH.
