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

Abstract

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 (2.12%) of incomplete 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 studu groups (p=0.188). Only 3 patients of the control group require repeat spinal block. The frequency of sensory (p=0.001) 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=0.007).
