The influence of different directions of the spoon-shaped incline of Tuohy needle for epidural puncture on postoperative back pain

To explore the effects of different directions of the spoon-shaped mouth of the epidural puncture of Tuohy needles on postoperative back pain. Method: 400 patients undergoing elective epidural anesthesia under abdominal, perineal and lower limb surgery were randomly divided into two groups A and B, each group In 200 cases, during epidural puncture in group A, the direction of the spoon-shaped mouth of the Tuohy needle was perpendicular to the longitudinal axis of the spine, and the direction of the spoon-shaped mouth of the B group was parallel to the longitudinal axis of the spine. Results: The incidence of back pain in group A was 12.5%, 8%, and 5% at 24, 48, and 72 h, respectively, while group B was 5.5%, 3.5%, and 1.5%. Group A was significantly higher than group B ( P<0.05), the degree and duration of postoperative back pain in group A were also significantly higher than those in group B. Conclusion: Epidural puncture with the direction of the spoon-shaped mouth of the Tuohy needle parallel to the longitudinal axis of the spine can reduce the incidence of postoperative back pain And degree.
