Study to include pregnant women of age 18 - 45 years undergoing cesarean section under spinal anaesthesia. The number of attempts (skin punctures, needle passes and needle redirections) for successful dural puncture will be noted. Successful identification of the subarachnoid space with one skin puncture and no redirection of the spinal needle will be considered as first pass success, landmark quality (good, poor, none), needle passes, space level change, second provider, bloody tap, intra operative fluid given will be observed. Postoperatively severity of PDPB will be assessed by visual analogue scale (VAS 1‑10) score; 0 = no backache,1–3 = mild backache, 4–7 = moderate backache, >7 = severe backache. And severity of PDPH will be assessed by NRS scale. On the scale, 0 is the absence of headache, 1–3 is mild pain, 4–6 is moderate pain, and 7– 10 is severe pain (disabling; unable to perform daily activities). Postoperatively the incidence of PDPB and incidence of PDPH will be assessed on day 1,3, 5 of hospital stay. In the study phone number of the patient/attender will be taken, going to call them back after 1month, 2month, 3 month to know the well being of the patient, any side effects in particular to PDPB.

Statistical Analysis; The collected data will be entered in the Microsoft Excel 2016 and will be analysed wih IBM SPSS Statistics for Windows, Version 29.0.(Amonk,NY:IBM Corp)
