Key result
Pencil-point spinal needles had lower rates of postdural puncture headache (2.8%-4.0%) than the cutting Quincke needle (8.7%) in obstetric patients undergoing cesarean delivery (P=0.02).
Why the study?
Does the choice of spinal needle affect the incidence of postdural puncture headache and epidural blood patch rate in women undergoing elective cesarean delivery?
Population
1,002 women undergoing elective cesarean delivery under spinal anesthesia
Comparison
Five different spinal needles vs Compared against each other
Design

p-value: p=0.04
Pencil-point spinal needles result in lower rates of postdural puncture headache and need for epidural blood patch compared to cutting needles in obstetric patients undergoing cesarean delivery.
Vallejo et al. (2000) conducted an RCT in Elective cesarean delivery under spinal anesthesia (n=1,002). Pencil-point spinal needles (Gertie Marx, Sprotte, Whitacre) vs. Cutting spinal needles (Atraucan, Quincke) was evaluated on Incidence of postdural puncture headache (PDPH) (p=0.04). Pencil-point spinal needles had lower rates of postdural puncture headache (2.8%-4.0%) than the cutting Quincke needle (8.7%) in obstetric patients undergoing cesarean delivery (P=0.02).
