The effect of needle type (25G Sprotte vs Quincke) in spinal anesthesia on the incidence of transient neurologic syndrome
Research Square (Research Square)(2023)
Abstract
Abstract Purpose : Transient neurologic syndrome (TNS) is a postoperative pain in the back and buttock that can occur after spinal anesthesia. The spinal needle design may have an impact on the occurrence of TNS. We decided to compare the incidence of TNS and related factors between two spinal needle types. Methods : In this randomized clinical trial, 150 patients aged 18 to 60 years and ASA physical status I who underwent lower abdomen or lower extremity surgeries with spinal anesthesia and supine position were enrolled. They were randomly divided into two groups (25G Quincke or Sprotte needle) with 0.5% bupivacaine (12.5 mg). After the operation, the patients were asked to report any pain in the lower back, buttock, and thigh areas. A VAS was also used to record the severity of the pain. Results : Overall, 45 patients developed TNS. Twenty-nine patients in Sprotte group (38.7%) and 16 patients in Quincke group (21.3%) developed TNS (P= 0.75). More patients in the Sprotte group (25.3%) had severe pain (VAS score of 8 to 10) when compared to the Quincke group (6.7%). There was no significant difference in TNS symptoms duration between the two groups. In about half of patients (51.9%) in the Sprotte group and 57.3% of patients in the Quincke group, the symptoms resolved after 2 to 3 hours. Conclusion : Although the incidence of TNS did not differ significantly, patients for whom Sprotte spinal needle had been used had more severe pain. This suggests that the Quincke needle caused less severe pain.
