Abstract

Objective: Evaluate the effectiveness of pain relief after total knee replacement surgery using continuous anesthetic infusion through the adductor canal combined with IPACK compared with epidural analgesia. Method: Randomized controlled clinical intervention study, a total of 60 knee replacement surgery patients were divided into 2 groups by random drawing: NMC group: Patients receiving pain relief with drug infusion Continuous anesthesia through NMC catheter; OI group: Patients received pain relief with continuous adductor canal block combined with IPACK. Monitoring patients within 48 hours after surgery, data are coded and processed according to statistical methods. Results: VAS scores at rest and when bending the knee to 45 degrees at hours 3, 6, 12, 18, 24, 36, 48 of the OI group were significantly higher than the NMC group but still achieved VAS<4. In both groups, no patient needed to use morphine for pain relief. 100% of patients in the OI group were satisfied or very satisfied compared to the NMC group at 96.67%, the difference was not statistically significant. The level of motor inhibition of the quadriceps muscle of the OI group was lower than that of the NMC group, the proportion of patients with a bromge score of zero was 96.67%, significantly higher than that of the NMC group (80%). Conclusion: To reduce pain after total knee replacement surgery, continuous adductor block combined with IPACK is not as effective in reducing pain as the NMC method but still achieves the pain reduction goal of VAS<4; However, quadriceps motor inhibition was lower than in the NMC group.
