The object of this study was to evaluate the effect ofgauze and type of spinal needle in causing post dural puncture headache (PDPH) in parturient undergoing LSCS. Seventy five parturient ASA grade I and grade II , age 20­35year with singleton uncomplicated pregnancy, who were randomized into three group I, II, and III received spinal anaesthesia using 25G quincke, 27G quincke and 25G whitacre needle respectively. Patients were interviewed on first, second, third and fourthday , after surgery, and were questioned with regard to incidence of headache, its severity, location, character, duration and associated symptoms like nausea, vomiting, auditory, ocular symptoms, and backache.The observations were analyzed by chi square and student t test. Statistical significance was assumed when p was <0.05. Incidence of PDPH was 20% in group I, 12% in group II and 4% in group III, which was not statistically significant. Among patients who developed headache, majority of patient had mild generalized headache. Most of patients develop PDPH on first postoperative day. Although the incidence of headache was statically similar among three groups, but clinically the headache was lesser in patients who received subarachnoid block with 25G whitacre spinal needle is compared to 25G quincke and 27G quincke spinal needle. 25G whitacre spinal needle is appropriate to minimize post dural puncture headache in cases of caesarean section.
