Sprotte versus Quincke Spinal Needles on the Frequency of Spinal Anesthesia Success in Patients undergoing Cesarean Section Delivery

In previous studies, the anesthesia technique was performed by different people and different results were reported, which makes comparisons difficult.

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.

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.

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.
