The prospective double blind randomized study was done in 150 patients under 45 years to compare the difficulties in clinical use between 29 G Quincke and 27 G Whitacre needles and postdural puncture complications. All patients received standardized dose of 0.5% hyperbaric bupivacaine and either 29 G Quincks or 27 G Whitacre spinal needle. The duration of needle insertion, failure of the procedure and the incidence of post dural puncture headache (PDPH) were observed. Result : The duration of needle insertion in 29 G Quincke (90 seconds) is longer than 27 G Whitacre needle (35 seconds) (p < 0.05). There was no difference in the failure rate of needle insertion and the incidence of PDPH between two groups.We concluded that 29 G Quincks was more difficult to use than 27 G Whitacre needle by increasing duration of needle insertion. There was no difference in the post dural puncture complications.
