Post spinal headache lasts for ?
Ans. is 'c' i.e., 10 days Post dural puncture headache is due to CSF leak. Typical location is bifrontal or occipital. Headache gets worsen on sitting or upright posture and is relieved by lying down position and abdominal pressure --> The hallmark of postdural puncture headache i.e., association with body position. The onset of headache is usually 12-72 hours following the procedure, however, it may be seen almost immediately. In most cases it lasts for 7-10 days. PDPH is believed to result from leakage of CSF from a dural defect and decreased ICT. Loss of CSF at a rate faster that it can be produced causes traction on structure suppoing the brain, paicularly dura and tentorium. Traction on cranial nerve (paicularly 6th nerve) produces diplopia. Factors that increase the incidence of PDPH are young age, female sex, Pregnancy, large bore needle and multiple punctures. Use of small bore needle can prevent PDPH . Intially conservative treatment is given which includes analgesics (NSAIDs), oral or i.v., fluids, Sumatriptan, cosyntropin, caffeine and recumbent position. If conservative treatment fails, epidural blood patch can be used. It involves injecting 15-20 ml of autologus blood into the epidural space which stop leakage of CSF by coagulation and mass effect
