Incidence of Post‑dural Puncture Headache: A Comparison of Quinckes’ Versus Whitacres’ Spinal Needles

Background: Repeated attempts at insertion, block failure, and post‑dural puncture headache are the most common drawbacks of spinal anesthesia. This study was designed to re‑evaluate these untoward effects of subarachnoid block. The primary aim of the study is to compare the incidence of post‑dural puncture headache with 25‑gauge Quincke’s and Whitacre’s spinal needles. The secondary objectives include assessing the difference in attempt rate and failure rate during subarachnoid block. Materials and Methods: In this randomized prospective study, 100 American Society of Anesthesiologists physical status I and II adult patients of both sex undergoing surgery below umbilicus under subarachnoid block were assigned in to two equal groups of 50 each; they were to receive spinal anesthesia either with Quincke’s (group QC) or Whitacre’s (group WP) spinal needles. The incidence of post‑dural puncture headache, number of attempts required for successful insertion, and frequency of failed subarachnoid block were recorded. Data obtained were analyzed using t‑test and Chi‑square test. A value of P < 0.05 was deemed as statistically significant. Results: All the 100 patients completed the study. Significantly high rate (P = 0.009) of post‑dural puncture headache was recorded in Quincke group (18%) as compared to Whitacre group (2%). In addition, the number of attempts required were less with Whitacre’s needle; however, no statically significant association between the type of the needle, attempt rate, and failure rate during spinal anesthesia could be detected (P = 0.2425). Conclusion: Overall to reduce the number of attempts and the incidence of post‑dural puncture headache, Whitacre’s 25‑gauge spinal needle has better option than Quincke’s 25‑gauge spinal needle for subarachnoid block.
