Present study designed to evaluate and compare the role of 25 gauge Quincke and Whitacre spinal needles on technical difficulties and incidence of Post dural puncture headache in 18 to 65 years of age group patients, undergoing surgeries under spinal anesthesia. One hundred and fifty patients of American Society of Anesthesiology physical status grade I, II and III, aged between 18-65 years of either sex, undergoing elective surgical procedures under spinal anesthesia, were enrolled for the study period. In group Q 75 patients received spinal anesthesia through a Quincke needle. Whereas, in group W, 75 patients received spinal anesthesia through a Whitacre needle. PDPH was assessed in all patients including associated symptoms and numeric Pain Rating Scale. It was concluded that shape of the tip of the needle has no effect either on the number of attempts for a successful intrathecal anesthesia or on the incidence and severity of postdural puncture headache. The overall incidence of post dural puncture headache is 2.7% and we did not observe any difference between 25G Quincke and 25G Whitacre needle on the incidence of PDPH (2.7% in both groups).
