Comparison of Sprotte and Quincke Spinal Needles on the Frequency of Spinal Anesthesia Failure in Patients undergoing Cesarean Delivery

Introduction: The aim of the present study was to compare Sprotte and Quincke spinal needles on the frequency of spinal anesthesia failure in patients undergoing cesarean delivery.Materials and Methods: In this randomized and double-blind clinical trial, ۱۰۰ pregnant women in ASA class I or II, term and single pregnancies who were candidates for elective cesarean section with spinal anesthesia were studied. In patients of the study group (n=۵۰), spinal anesthesia was performed using Sprotte spinal needle ۲۵G and in patients of the control group (n=۵۰) with Quincke's spinal needle ۲۵G. The frequency of spinal anesthesia failure was recorded as complete and partial failure.Results: In the study group, one patient of incomplete failure two patients with complete failure; and in the control group, ۲ patients of incomplete failure and ۳ patients of complete failure were observed, which was not a statistically significant difference between the two study groups (p=۰.۷۴۹). Only ۳ patients of the control group require repeat spinal block. The frequency of sensory (p=۰.۰۰۲) and motor (p=۰.۰۰۱) block for surgery was significantly higher in the study group than in the control group. The Post-Dural puncture headache (PDPH) was significantly higher in the control group (۱۴% vs. ۰%; p=۰.۰۰۶).Conclusion: The frequency of spinal anesthesia failure and post-Dural puncture headache (PDPH) using Sprotte spinal needle was lower than in Quincke needle in patients with spinal anesthesia for cesarean delivery.
