Application Of NRS Combined With Four-grade FAS In Pain Management After Total Hip Arthroplasty

Objectives: To explore the application effect of NRS combined with four-grade FAS in postoperative pain management of patients with hip replacement,and to analyze the advantages of NRS combined with four-grade FAS scoring in pain management.Methods: 90 patients with hip replacement who received treatment in the orthopedics department of a Grade-III hospital in Kunming,Yunnan Province from November 2021 to September 2022 and met the inclusion and exclusion criteria were selected as research objects,and divided into the experimental group and the control group with 45 patients in each group by using random number table method.In the control group,the patients evaluated their resting and active pain respectively by the conventional NRS scoring method,and the corresponding pain intervention measures were given according to the NRS score.In the experimental group,on the basis of the control group,the nurses used the four-grade FAS score to evaluate the patients’ active pain,and implemented targeted pain intervention measures according to the results of NRS and four-grade FAS score.The baseline data of the two groups were collected before operation,and the highest resting and activity scores of the two groups were collected on the day after operation and after pain treatment using NRS and four-grade FAS scale.The Harris scale score was completed before intervention and 7 days after operation.The number of times higher than the target of pain management and the length of postoperative hospital stay of the two groups were counted one day before discharge.SPSS26.0 statistical software was used to analyze the data.Results:1 There was no significant difference in baseline data between the two groups before intervention(P > 0.05).The most severe resting NRS score,active NRS score and the highest FAS score of the four grades of patients in the two experimental groups were lower than those in the control group on the day after operation and on the 1st,2nd and 3rd day after operation(P<0.05).The Harris score of the three experimental groups on the 7th day after operation was lower than that of the control group,and the difference was statistically significant(P<0.05).The number of times of postoperative pain target management in the four experimental groups was lower than that in the control group,and the difference was statistically significant(P<0.05).The postoperative hospital stay of the experimental group was lower than that of the control group,and the difference was statistically significant(P<0.05).Conclusion:The application of NRS combined with 4-level FAS pain assessment in patients after hip arthroplasty can improve resting pain and MEP,reduce the number of target management of postoperative pain,improve the level of postoperative pain management,promote early functional recovery,and shorten the postoperative hospital stay.
