Clinical effect of ropivacaine intrathecal injection on carpal tunnel syndrome with nervi medianus entrapment syndrome / 中国生化药物杂志

ABSTRACT

Objective To investigate the effect of intrathecal injection of ropivacaine in the treatment of carpal tunnel syndrome with nervi medianus entrapment syndrome. Methods 164 patients with carpal tunnel syndrome were selected and divided into two groups, 82 cases in the control group were given intrathecal injection of lidocaine + methylprednisolone + vitamin B1, 82 cases in the experimental group received injection of ropivacaine + methylprednisolone + vitamin B1, the symptom score, nerve electrophysiological examination index, high frequency ultrasound quantitative parameters, the clinical effect and total recurrence rate were compared after treatment. Results The effective rate in the control group(74.39%)was lower than the experimental group(87.81%)(P<0.05); compared with the control group, the visual analogue scale (VAS), global symptom score (GSS), fatigue severity scale (FSS) and Levine carpal tunnel syndrome questionnaire score were lower in the experimental group after treatment, the nervi medianus distal motor latency (DML) level was lower, sensory nerve action potential (SNAP) and sensory conduction velocity (SCV) levels were higher after treatment, the diameter of the nervi medianus, the transverse diameter (a), anteroposterior diameter (b) of nervi medianus and cross sectional area (CSA) were lower after treatment, with significant difference (P<0.05); the total recurrence rate in the control group(53.66%)was higher than the experimental group(37.80%), with significant difference (P<0.05). Conclusion The clinical effect of intrathecal injection of ropivacaine in the treatment of carpal tunnel syndrome with nervi medianus entrapment syndrome was obvious, can effectively alleviate pain, improve the symptoms of nervi medianus entrapment, restore the nervi medianus conduction velocity and function, and reduce the recurrence rate.
