Epidural injection of Ropivacaine Mesylate anesthesia in transforaminal endoscopic surgery / 中国生化药物杂志

ABSTRACT

Objective To compare and analyze the clinical effects of different local anesthetics on continuous epidural anesthesia for percutaneous enucleation of nucleus pulposus. Methods A total of 40 patients underwent lumbar intervertebral discoscopy (PTED) from November 2015 to November 2016, according to the choice of anesthesia is divided into group A and group B, 20 cases in each group. Group A used 0.5％lidocaine local anesthesia, group B treated with continuous epidural anesthesia (1 ％ lidocaine 3 mL+0.5％ ropivacaine).Analysis of two groups before operation, the curative effect, VAS score, modified Bromage score, intraoperative pain perception includes four criteria, namely, mild, moderate and severe, the former two satisfactory anesthetic effect; the latter two are not satisfied with the anesthesia. Results Two cases without postoperative cerebrospinal fluid leakage occurred, nerve root injury and other complications; two groups of patients with pain satisfaction difference was statistically significant (P<0.05); compared with group A, the levels of HR and MAP in group B were more stable (P<0.05). Conclusion Continuous epidural anesthesia is more suitable for PTED than local anesthesia. It can reduce the pain and the occurrence of cardiovascular and cerebrovascular accidents in patients, and does not affect the patients' lower limb movement score.
