Clinical Study Of Multimodal Analgesia For Postoperative Analgesia In Patients Undergoing Total Knee Arthroplasty

ObjectivesTo provide an economical and effective postoperative analgesia model for patients undergoing total knee replacement,and to provide better clinical guidance for early functional exercise and long-term rehabilitation of postoperative patients.MethodsA prospective randomized controlled study method on November 2015 to November 2016 in Qingda University Affiliated Hospital joint surgery undergoing primary unilateral TKA in 80 patients,clinical study of multimodal analgesia.Data collection was completed by means of the investigation of medical records and clinical examination.Using SPSS19.0 statistical software for data analysis.For continuous variables,the results were expressed as mean ± standard deviation(mean ±SD);categorical variables were expressed as the number of cases(percentage)(N;%).Repeated measurement data were used to compare the variance of repeated measurement data,and the t test of group design data was used to compare the differences between groups with statistical significance of P<0.05.Results 1 Amplitude of the experimental group and the control group,the postoperative VAS scores at rest and activity were compared with statistical difference(Fgroup = 24.596,28.475,P<0.001).After 6,12,24,48,72 and discharge experimental group rest and activity VAS scores were significantly lower than those in the control group,rest and activity VAS scores were increased with time decreases(Ftime = 31.210,46.894,P<0.001);VAS scores at rest and activity were reduced after surgery in the experimental group were significantly higher than those in the control group(Finteraction = 9.972,15.819,P<0.001).2 In the experimental group and control group after ROM compared with statistical difference(Fgroup=37.814,P<0.001)and postoperative 24 h,48 h and 72 h in the experimental group ROM were significantly higher than those in the control group;postoperative ROM increased with the time increase(Ftime=51.657,P<0.001);increased ROM after surgery in the experimental group amplitude was significantly greater than that of the control group(Finteraction=19.234,P<0.001).3 The incidence of analgesia adverse reactions in the experimental group lower than in the control group and had statistically significant difference(?2=8.658,P=0.003).ConclusionsMultimodal analgesia can reduce postoperative pain in patients with TKA,improve the activity of the knee joint in patients with TKA,and reduce the incidence of adverse reactions,it is worthy of clinical application.
