Post-dural puncture headache (PDPH) is a major cause of morbidity in postpartum patients who receive neuraxial block for labour analgesia and/or caesarean delivery. Epidural blood patch (EBP) is the gold standard for its treatment, with a success rate upto 90%. However, it is likely to be associated with various adverse effects, like, subdural haematoma, infection, meningitis, and delayed radicular pain. Also, the procedure itself can cause another inadvertent dural puncture (DP). EBP is, therefore, never considered as the first line of management of PDPH. Patients are often offered conservative treatment including medications, bed rest, abdominal binders, and fluids for at least 24 hours prior to being offered an EBP. The sphenopalatine ganglion (SPG) block is found to be an effective treatment for PDPH in the obstetric population, the block could be offered to patients as a first-line treatment as a way to improve pain scores, reduce the need for medications with potential side effects, and possibly reduce the need for EBP. This randomized study done in 50 parturients aims to evaluate SPG block for management of PDPH in reducing the severity of pain and as a useful adjunct to the traditional treatment with oral or parenteral analgesics in this subset of patients. Parturients will be randomized into two groups:

Conservative group (Group C) – will receive IV paracetamol 1g 8 hrly

Sphenopalatine ganglion block group (Group S) - will receive SPG block

Parturients in both the groups will receive IV fluids (2L/day) and bed rest without pillow.
