Observation on the Application of Continuous Adductor Canal Block in Postoperative Analgesia of Patients Undergoing Total Knee Arthroplasty and Its Impact on Joint Range of Motion
Objective:To explore the application effect of continuous adductor canal block (CACB) in postoperative analgesia of patients undergoing total knee arthroplasty (TKA) and its impact on joint range of motion. Method:A total of 100 TKA patients treated in Shiyan Hospital of Integrated Chinese and Western Medicine from March 2020 to March 2023 were selected. They were divided into control group (50 cases) and observation group (50 cases) according to random number table method. The observation group received CACB analgesia,and the control group received intravenous analgesia. Postoperative pain degree,knee joint motion,the number of analgesic pump compression and remedial analgesia,and the occurrence of adverse reactions were compared between the two groups. Result:Visual analog scale (VAS) scores at 6,12,24 and 48 h after operation in the observation group were lower than those in the control group,knee joint motion in both groups gradually increased at 12,24,48 and 72 h after operation,and knee joint motion in the observation group were higher than those in the control group at all time points after operation,the number of analgesic pump compression and relief analgesia in the observation group were less than those in the control group within 72 h after operation,the differences were statistically significant (P<0.05). There was no significant difference in the incidence of adverse reactions between the two groups (P>0.05). Conclusion:CACB can improve the postoperative analgesic effect and joint mobility of TKA patients without increasing adverse reactions.
