Comparison of the efficacy and safety of ropivacaine mesylate and hydrochloride ropivacaine in epidural anesthesia

Objective To compare the effect and safety of ropivacaine mesylate with ropivacaine hydrochloride in epidural anesthesia of patients make hypogastric region and lower extremity operation.Methods 126 patients with epidural anesthesia were divided into two groups,each group 63 cases.The observation group was administered with ropivacaine masylate,and the control group was administered with ropivacaine hydrochloride.The sense of pain block plane and effective-acting period and effect time,sports block rating and effect-acting period and duration,vital signs,adverse events and serious adverse events were observed.Results There were no significant differences between the two groups on sense of pain block plane and effective-acting period and effect time,sports block rating and effect-acting period and duration,Bp,HR,SpO2,chang of ECG,bleeding in operation( t =13.23,10.52,10.64,12.21,13.23,10.52,10.64,12.21,6.11,5.34,5.23,6.05,all P ＞ 0.05 ).Conclusion The results of ropivacaine mesylate used for anesthesia epidural was satisfied and had no obvious side effects as well as ropivacaine hydrochloride.
