Clinical Study Of Epidural Analgesia Combined With Cocktail Therapy On Analgesia After Knee Replacement

Background:With the economic and social development,the aging of the population,more and more elderly people are suffering from osteoarthritis.Osteoarthritis is a degenerative disease,due to age,obesity,strain,trauma and other factors caused by articular cartilage degradation injury,joint edge and subchondral bone reactive hyperplasia.Clinical manifestations of slow development of joint pain,tenderness,stiffness,joint swelling,is limited mobility and joint deformities.At present,the main knee arthroplasty(TKA)is the most effective method for the treatment of osteoarthritis.It can play a role in relieving pain,correcting joint deformity and restoring motor function,Favored by the elderly patients.However,due to the age of patients with osteoarthritis,It is generally large,and TKA postoperative pain factors,postoperative pain affect patient satisfaction and joint function recovery.Therefore,postoperative pain management becomes an unavoidable problem.At present,there are many analgesic programs in clinical practice,but thereis no ideal treatment plan.Through retrospective study,the analgesic effect of epidural analgesia pump combined with cocktail therapy after artificial knee arthroplasty was analyzed.Aim:TKA perioperative analgesic methods are more,including nerve block,oral medication,controlled analgesia pump.In this study,the patients were treated with mixed analgesic drugs(cocktail therapy)and postoperative epidural analgesia combined with analgesia to control the pain after knee arthroplasty,to reduce the adverse reactions and to promote early exercise Knee joint,improve knee treatment and patient satisfaction.Methods:Sixty patients undergoing knee arthroplasty were divided into three groups according to the principle of random assignment.Twenty patients were randomly divided into two groups.A group of patients with intraoperative joint cavity around the injection of cocktails and postoperative epidural analgesic pump;group B patients only in the intraoperative joint cavity around the injection of cocktails;C group only after surgery to place epidural analgesia pump.Visual analogue scale(VAS)was performed in 3 groups of patients.Results:The VAS score and the VAS score of the analgesic pain werestatistically significant(P <0.05).The scores of group A(group)were lower than those of group B and group C(P <0.05)at 2h,4h,8h,12 h,24h,36 h and 48 h after 2 hours,4 hours,12 h,(P <0.05).The score of group A was lower than that of group B and group C(P <0.05).No matter what kind of analgesic,patients with rest pain after 24 hours to reach the peak,activity pain 36 h after surgery to reach the peak.There were no statistically significant differences in postoperative incisional infection,delayed healing,and tissue necrosis(P> 0.05).Conclusions:Epidural analgesia pump combined with cocktail therapy has a positive effect on relieving pain after knee arthroplasty,which can effectively reduce the postoperative pain and activity pain VAS score;pay attention to changes in pain in patients with clinical pain relief help.Combined therapy does not increase postoperative complications,promote early functional exercise,early functional recovery of joint function,is conducive to improving patient satisfaction.
