sprotte versus quincke spinal needles on the frequency of spinal anesthesia success in patients undergoing cesarean section delivery

Background: in previous studies, the anesthesia technique was performed by different people and different results were reported, which makes comparisons difficult. aim: this study aimed to compare sprotte (non-cutting) and quincke (cutting) spinal needles on the frequency of spinal anesthesia success in patients undergoing cesarean delivery. method: this double-blind randomized clinical trial study was performed in 2019 on 100 pregnant women in asa class i or ii with term and single pregnancies who were candidates for elective cesarean section with spinal anesthesiain tabriz al-zahra hospital. spinal anesthesia was performed using sprotte spinal needle 25g in the intervention group (n=50) and with quincke's spinal needle 25g in the control group (n=50). the frequency of spinal anesthesia failure was recorded as complete and partial failure. data were analyzed using spss.16 software. p<0.05 was considered statistically significant. results: in the sprotte group, there was one patient with incomplete failure and two with complete failure; in the quincke group, there were 2 patients with incomplete failure and 3 with complete failure; the two groups were not significantly different (p=0.749). three patients in the quincke group required repeated spinal block. the frequency of sensory (p=0.002) and motor (p=0.001) block for surgery was significantly higher in the sprotte group. the post-dural puncture headache (pdph) was significantly higher in the quincke group (p=0.006). implications for practice: the post-dural puncture headache (pdph) using sprotte spinal needle was lower than using quincke needle in patients with spinal anesthesia for cesarean delivery
