Abstract:

BACKGROUND: Analgesia in different ways can be selected for the elderly in hip and knee arthroplasty. Considering the actual situation of the elderly patients, choice of anesthesia should be reasonable in order to achieve fast acting, long lasting time and good analgesic effect.
OBJECTIVE: To explore the analgesic effect of ropivacaine of lumbar epidural anesthesia on elderly knee arthroplasty.
METHODS: A total of 78 elderly patients aged 80-96 years, who were treated with hip and knee arthroplasty in the Shenyang Orthopaedic Hospital from September 2011 to September 2014, were enrolled in this study. They were equally and randomly assigned to control group and observation group, and separately administered continuous epidural anesthesia and lumbar epidural anesthesia with ropivacaine. The excellent and good rate, onset time, anesthetic induction, frequency of use of Duffing mixture, and adverse reactions were compared between the two groups.
RESULTS AND CONCLUSION: The excellent and good rate of analgesic effect was higher in the observation group (97%) than in the control group (87%) (P < 0.05). Onset time was significantly shorter, the dose of anesthetic was significantly less, frequency of use of Duffing mixture was significantly less in the observation group than in the control group (P < 0.05). The difference was not significant in adverse reactions between the two groups (P > 0.05). Above results indicated that lumbar epidural anesthesia of ropivacaine obtained good 
analgesic effects during elderly knee arthroplasty.
