(The Analgesic Efficacy Of Ropivacaine Incision Infiltration After Lumbar Discectomy)

Objective:To evaluate the feasibility of postoperative ropivacaine local infiltration in lumbar surgery.Methods:Sixty ASA I or II patients undergoing lumber surgery were randomized into two groups(groups A and B) with30each. Group A received ropivacaine75mg sprayed into the incision after closed muscle layer,and additional50mg infiltrate incision at the end of surgrey. Group B received PCA with fentanyl postoperation,PCA pump contained:fentanyl lmg and Ondansetron Hydrochloride16mg.Bodycomfort score (BCS) and Visualanalog score (VAS) were recorded at2,6,12,24h postoperatively.Observe the postoperative adverse event,including dizziness,nausea,convulsions,low blood pressure and abnormal bleeding.Observe the intertion status after operation.ResuIts:Group A and group B were no significence in BCS scores (P>0.05).VSA scores in group A were significantly lower than that in group B at2h postoperatively (P<0.05),but both two group were no significence at6,12,24h (P>0.05).Dizziness in group A were significantly less than that in group B at2,6h postoperatively (P<0.05),but dizziness in both two group did not happened at12,24h postoperatively.Incidence of Nausea in group A were less than group B postoperatively.The other adverse event,including convulsions,low blood pressure and abnormal bleeding did not happened both in group A and group B.Conclusion:infiltration with ropivacaine was good for postoperative analgesia of lumber discectomy and the incidence of adverse was signnifiantly lower,also had lower cost.Therefore,local infiltration of ropivacaine was a good method for postoperative analgesia of lumbar discectomy.
