Abstract:Objective: To analyze the effect and safety of ultrasound-guided continuous femoral nerve block (CFB) for analgesia in knee surgery. Methods: From March 2021 to June 2024, 103 patients with knee injuries who underwent knee surgery in the hospital were selected as the study subjects. They were grouped by random number table method. The control group (n=51) received patient-controlled intravenous analgesia (PCIA), while the observation group (n=52) received ultrasound-guided CFB for analgesia. The two groups were compared on analgesic effect [Visual Analogue Scale (VAS) score for pain], inflammatory response indicators [interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and C-reactive protein (CRP)], the incidence of postoperative delirium, and adverse reactions. Results: Compared with the control group, the observation group showed reductions in VAS in resting state at 8h, 12h, 24h, and 48 h after surgery and VAS in the motion state at 4h, 8h, 12h, 24h, and 48h after surgery (P<0.05). After surgery, the levels of inflammatory markers in both groups increased, and the levels were lower in observation group (P<0.05). Delirium was observed in the control group on the 1st, 2nd, and 3rd day after surgery, and in the observation group on the 2nd day. No delirium was observed in the two groups on the 4th, 5th, 6th, and 7th day after surgery. The total incidence of delirium was lower in the observation group (P<0.05). Both groups showed an increase in knee range of motion (KSS) scores after surgery. At 24h and 49h after surgery, the observation group had higher KSS scores than the control group (P<0.05). Two (3.85%) patients in the observation group and ten (19.61%) in the control group received additional use of analgesics. There were fewer patients receiving remedial analgesia in the observation group compared with the control group (χ2=6.214, P=0.013). The total incidence of adverse reactions was 19.23% in the observation group, lower than 49.02% in the control group (P<0.05). Conclusion: Ultrasound-guided CFB can achieve a good analgesic effect in patients undergoing knee surgery. It can inhibit inflammatory response and reduce the occurrence of delirium and adverse reactions.
