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, 100 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=50), spinal anesthesia was performed using Sprotte spinal needle 25G and in patients of the control group (n=50) with Quincke's spinal needle 25G. 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, 2 patients of incomplete failure and 3 patients of complete failure were observed, which was not a statistically significant difference between the two study groups (p=0.749). Only 3 patients of the control group require repeat spinal block. The frequency of sensory (p=0.002) and motor (p=0.001) 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 (14% vs. 0%; p=0.006).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
