After TKA Continuous Femoral Nerve Block Analgesia Effect Of Early

Objective:1.To comparet Total knee arthroplasty(TKA)postoperative continuous femoral nerve block analgesia(CFNB)and Patient controlled intravenous analgesia(PCIA)on the early postoperative analgesia after total knee replacement effect.2.To evaluate Total knee arthroplasty (TKA) postoperative continuous femoral nerve block analgesia (CFNB) for total knee arthroplasty in patients with early knee function recovery effect.Methods:Retrospective analysis of 60 cases in our hospital in 2014 January -2015 year in January ASA Ⅰ-Ⅱ unilateral total knee replacement operation patients. According to the means of postoperative analgesia with different randomly divided into CFNB group (The treatment group), PCIA group (the control group),including 30 cases of CFNB group, PCIA group of 30 cases. Observation indexes:after 6,12,24,48,72h ipsilateral knee rest pain VAS score and postoperat ive 1,2,3,5,7d ipsilateral knee movement pain VAS score; after 1,2,3,5,7d of ipsilateral knee joint activity (ROM value); after 1,3,5,7d limb femoral head four muscle force;the incidence of postoperative adverse reactions in 7d; preoperative and postoperative HSS score at 3 months; Time after operation.Results:1.No significant postoperative pain in 6h differences between the two groups (P> 0.05); after 12,24,48,72 h, CFNB group the rest pain was less than PCIA group, and the difference was statistically significant (P< 0.05);2.After 1,2,3,5D. CFNB group activity pain degree was less than PCIA group, and the difference was statistically significant (P< 0.05);No significant postoperative pa-in 7d motion differences between the two groups (P> 0.05);3.After 1,2,3,5,7d, CFNB group of ipsilateral knee joint activity (ROM value) was significantly higher than that in PCIA group, and the difference was statistically significant (P< 0.05);4.After 1,3,5,7d, CFNB group of limb muscle strength is greater than the average of four shares of PCIA group, and the difference was statistically significant (P< 0.05);5. The ratio of adverse reaction after operation in 7d in PCIA group was significantly higher than that of CFNB group, and the difference was statistically significant (P< 0.05);6.The preoperative HSS score at 3 months difference between the two groups was not statistically significant(P> 0.05), postoperative HSS score in CFNB group than PCIA group, and the difference was statistically significant (P< 0.05);7.Time after operation, CFNB were significantly lower than PCIA group, and the difference was statistically significant (P< 0.05).Conclusion:Compared with PCIA analgesia, postoperative CFNB clinical analgesic effect more obvious, can alleviate after TKA early knee joint pain, increased joint motion activity, significantly shorten the hospitalization time, promote joint exercises are good for functional rehabilitation, and does not increase the birth rate and other advantages of nausea, vomiting and other adverse reactions.
