In this study, each patient's analgesia was directed by the doctor in his or her department, and other departments were invited to consult if necessary.1. Admission evaluation: The emergency medical staff carried out the first comprehensive evaluation after the patient was admitted to the hospital, and the contents were the same as those of the test group.2. Analgesic scheme: This scheme was the same as that in the test group.3. FICB: This was performed when the emergency or orthopaedic doctor considered it necessary or had asked the anaesthesiologist for a consultation.4. Pain self-assessment: This was consistent with the guidance provided to the test group.After participating in the trial, those patients who entered the intensive care unit preoperatively were excluded. Patients who ultimately did not undergo surgery were excluded from the trial. Patients with unplanned surgery during this hospitalization, that is, any surgery except for a single hip fracture surgery (including internal fixation and total/half hip replacement), were excluded.The anaesthesia method was not limited during the operation, and the postoperative analgesia scheme comprised a single FICB and an intravenous analgesia pump containing sufentanil.
