Hospital based prospective and double blind randomised control trial - Comparision of efficacy of sphenopalatine ganglion block with intra nasal 4% lignocaine v/s intra nasal dexmedetomidine v/s conservative treatment of post dural puncture headache in patients undergoing surgery under spinal anaesthesia

Post-dural puncture headache (PDPH) is a common and distressing complication following spinal anaesthesia. Conservative management often provides delayed relief and may prolong hospital stay. Sphenopalatine ganglion block (SPGB) using intranasal agents is a minimally invasive technique that has shown promising results in the management of PDPH. This hospital-based, prospective, double-blind randomized controlled trial aims to compare the efficacy of intranasal 4% lignocaine, intranasal dexmedetomidine, and conservative treatment in patients developing PDPH after surgery under spinal anaesthesia. The primary outcome will be the reduction in headache severity, while secondary outcomes will include duration of analgesia, need for rescue analgesics, and incidence of adverse effects. The results of this study may help identify an effective, safe, and non-invasive treatment option for PDPH.
