Investigation And Study On Chronic Post-surgical Pain After Artificial Joint Replacement Applied The Thought Of "Preventive Treatment Of Disease"

Objective Chronic postoperative pain(chronic post-surgical pain,CPSP)is a high incidence of postoperative complications,which hinders the recovery of the patients and poses a serious threat to life and health.This study is based on the idea of "prevention and treatment of disease without disease".It is intended to investigate the incidence of chronic pain after total knee joint prosthesis replacement for patients with knee osteoarthritis of different clinical syndromes,and to grasp the incidence and severity of chronic pain after total knee prosthesis replacement(total knee arthroplasty,TKA).Clinical data of patients and their influence on their quality of life and psychological status.To review and analyze the patient’s medical records and to find out the risk factors of chronic pain after the replacement of the knee joint,and provide useful guidance to the clinician for the prevention of chronic pain after total knee replacement.Method Through the examination and approval of the ethics committee of Puyang Hospital of Traditional Chinese Medicine,from January 1,2017 to December 31,2017,the patients of knee osteoarthritis with different TCM Syndromes of selected artificial total knee prostheses in two families of the family of bone and bone were continuously included.The patient’s medical records were reviewed in order to understand the patient’s general situation,preoperative pain,anesthesia,operation and postoperative conditions.After the operation,the patients were contacted again in March,and after informed consent,the patient’s chronic postoperative pain was investigated by a concise pain questionnaire.Statistical Analysis The data were analyzed and processed with SPSS 22 software.and the measurement data were represented by the standard deviation(+ s)of the average number of soil.The statistical data were classified according to the total knee prosthesis replacement without CPSP,and the two groups were compared with the t test.The possible risk factors of CPSP were analyzed by Spearman correlation analysis.According to P<0.05,there were statistical differences.Result A total of 150 respondents completed the survey and were included in the statistical analysis.The total incidence of CPSP in March after total knee replacement was 48%and the pain was slight in the rest of the patients after total knee replacement,but the pain was severe in the exercise state.CPSP patients were also mainly mild pain after total knee replacement.accounting for 70.8%of the total number of postoperative CPSP patients,22.2%of CPSP patients with moderate pain and 6.9%of CPSP patients with severe pain,and 73.6%of patients with CPSP after total knee prosthesis replacement were treated with oral analgesics.The incidence of CPSP in patients with knee osteoarthritis after qi stagnation and blood stasis was 88.5%.The difference of BMI,weight,operation time and postoperative acute pain(NRS score of the day after operation and the day after operation,the day after operation and the average exercise pain NRS score)was statistically significant(P<0.05).However,there was no significant difference in age and postoperative hospital stay between the two groups.There was a significant positive correlation between CPSP and patient weight,body mass index(Body Mass Index,BMI),postoperative acute pain(NRS score on the day after operation and the day after operation,and the average exercise pain NRS score after the operation)and whether to participate in the rehabilitation training of Western Medicine(P)after artificial total knee prosthesis replacement(P<0.05).with the sex,age,height,type of prosthesis(import/domestic),primary and two replacement,smoking and drinking history,history of basic disease(without hypertension,diabetes,coronary heart disease),preoperative surgical site and the history of hand pain in other parts of the preoperative area,the same site and other parts of the operation.There was no significant correlation between history,operative time and postoperative hospital stay.Conclusion(1)the incidence of CPSP after total knee arthroplasty is high.(2)most of CPSP patients were mild pain(51/72)after total knee replacement and moderate pain(16/72)in a small number of patients,but there were still very few patients with severe pain(6/26).(3)compared with group CPSP and non CPSP group after total knee arthroplasty,there were significant differences in BMI,weight,operation time and postoperative acute pain(NRS score on the day and day after operation,and the average pain NRS score on the day after the operation and the day after the operation).(4)there was a significant positive correlation between CPSP and weight,BMI,the degree of acute postoperative pain after artificial total knee replacement(the day after the operation and the mean rest pain NRS score,the day after operation and the average exercise pain NRS score)and the acceptance of the system of integrated and Western medical rehabilitation training.
