Objective: To investigate the impact of ultrasound-guided fascia iliaca compartment block(FICB) site selection on serum pain-related indicators, stress indicators and prognosis of patients after total hiparthroplasty(THA).Methods: A total of 92 patients who undergo THAwere selected. According to the location of FICB after operation, they were divided into the study group and the control group,46 cases in each. The study group received FICB analgesia above the inguinal ligament and the control group received FICB analgesia under the inguinal ligament.The clinical efficacy differences between the two groups were compared.Results: The number of patient-controlled analgesia, sufentanil consumption and the incidence of adverse reactions in the study group within 72 hours after surgery were significantly lower than those in the control group(P<0.05); The success rates of sensory block on obturator nerve and lateral femoral cutaneous nerve in the study group were significantly higher than those in the control group, serum pain-related indicators andstress indicatorsin the study group were better than those in the control group, the scores of quality of life in the study group were higher than those in the control group(all P<0.05).Conclusion: The effects of FICB analgesia above the inguinal ligament are better than FICB under the inguinal ligament. It can reduce the postoperative stress response and improve the quality of life of THA patients, which is worthy of clinical application.
