Abstract 【Objective】 To investigate the effect of ultrasound-guided modified lumbar plexus block(LPB) in patients undergoing total hip arthroplasty (THA).【Methods】 A total of 120 patients undergoing THA in our hospital were divided into an observation group and a control group according to different preoperative anesthesia methods, with 60 patients in each group. The observation group received ultrasound-guided modified LPB combined with sacral plexus block, while the control group received ultrasound-guided LPB combined with sacral plexus block. Clinical indicators and anesthetic effects were compared between the two groups. Hemodynamic parameters, including mean arterial pressure (MAP) and heart rate (HR), were recorded upon entering the operating room (T₀), 5 minutes after anesthesia (T₁), and 30 minutes after the start of surgery (T₂). Serum pain-related factors-prostaglandin E₂ (PGE₂), neuropeptide Y (NPY), and nerve growth factor (NGF) were measured before entering the operating room and 12 hours postoperatively, and adverse reactions were recorded.【Results】 There were no significant differences between the two groups in terms of puncture time, block completion time, surgical duration, and femoral nerve recovery time (P>0.05). Intraoperative sufentanil consumption was significantly lower in the observation group than in the control group (P<0.05). No significant differences were observed in MAP and HR between the two groups at each time point (P>0.05); however, MAP and HR at T₂ in the observation group were significantly lower than those at T₀ and T₁ within the same group (P<0.05). The excellent-to-good anesthesia rate was significantly higher in the observation group (98.33%) than in the control group (88.33%) (P<0.05). Serum PGE₂, NPY, and NGF levels at 12 hours postoperatively were higher than preoperative levels in both groups (P<0.05), but they were significantly lower in the observation group than in the control group (P<0.05). There was no significant difference in the incidence of adverse reactions between the two groups (P>0.05).【Conclusion】 Ultrasound-guided modified LPB in THA provides effective anesthesia, reduces opioid consumption, and improves postoperative analgesia.
