Key result
The 27 G Whitacre spinal needle significantly reduced the incidence of post-dural puncture headache compared to the 27 G Quincke needle (1.1% vs 3.1%, p<0.005).
Why the study?
Does the use of 27 G Whitacre needles compared to 27 G Quincke's needles reduce the incidence of post-dural puncture headache in patients undergoing subarachnoid block?
Population

Karigar et al. (2016) conducted an RCT in Lower abdominal and lower limb surgeries requiring spinal anesthesia (n=196). 27 G Whitacre spinal needle vs. 27 G Quincke spinal needle was evaluated on Incidence of post-dural puncture headache (PDPH) (p=<0.005). The 27 G Whitacre spinal needle significantly reduced the incidence of post-dural puncture headache compared to the 27 G Quincke needle (1.1% vs 3.1%, p<0.005).
