| Abstract: Objective The aim of this study was to evaluate the analgesic effect of acupuncture stimulation combined with dizocin intravenous self-controlled analgesia (PCA) in patients undergoing total knee arthroplasty (TKA) and to investigate its potential advantages in reducing postoperative pain, improving knee function, and increasing patient satisfaction. Methods In this study, 80 patients who underwent total knee arthroplasty were retrospectively selected and divided into two groups of 40 cases each according to the different analgesic modalities. The observation group used acupuncture stimulation combined with dizocin intravenous self-controlled analgesia program, while the control group only used dizocin intravenous self-controlled analgesia program. The main observational indexes included visual analog scores (VAS) in the immediate postoperative period, 6 hours, 24 hours, and 48 hours postoperatively, recording the consumption of analgesic medication, monitoring the occurrence of adverse reactions, and assessing the subjective feelings of patients through the Knee Function Score (HSS Score) and the Patient Satisfaction Questionnaire. Results The results showed that the VAS scores of the observation group were significantly lower than those of the control group at all time points of the postoperative resting state (P<0.05), and the VAS scores of the passive exercise were significantly lower than those of the control group at 24h and 48h postoperatively (P<0.05), suggesting that the patients in the observation group experienced a lesser degree of pain. Regarding adverse reactions, no significant differences were observed between the two groups. In addition, the total postoperative diazoxide consumption of patients in the observation group was significantly less than that of the control group (P<0.05). In terms of knee function scores, patients in the observation group had significantly better function scores than those in the control group at 24h and 48h postoperatively (P<0.05), suggesting that their knee function recovered more quickly. Finally, the overall satisfaction score of patients in the observation group was higher than that of the control group (P<0.05). Conclusion Based on the above findings, acupuncture stimulation combined with dizocin intravenous self-controlled analgesia showed superiority in analgesic management after total knee arthroplasty, which not only effectively reduced postoperative pain, but also promoted early recovery of knee function, reduced the dosage of analgesic medication, and improved patient comfort and satisfaction. Therefore, this combined treatment strategy is worthy of further promotion and application in clinical practice. |
