  5. Additional inclusion criteria may pertain to specific interventions and will be described in relevant sub-protocols.

Exclusion Criteria:

  1. Patients with multiple trauma or fractures (excluding trauma that the researcher judges will not affect the patient's overall recovery, such as simple spinal compression fractures, mild soft tissue contusions, fractures of hands and feet, etc.);
  2. Two or more anesthetic surgeries are required.
  3. Petients with an obvious history of head trauma (such as loss of consciousness for more than 5 minutes, post-traumatic amnesia, etc.);

How is the study designed?

Design Details

  • Primary Purpose: Prevention
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Nerve block + standard anesthesia protocol
(described in detail in sub-trial protocol 1)
  1. Receive nerve block as soon as possible after randomization;
  2. Ultrasound-guided nerve block is recommended, with the iliacfascia block recommended as the blocking site;
  3. It is recommended to use 1.33% bupivacaine liposome (long-acting), and the maximum dose should not exceed 133mg; or regular local anesthetic (bupivacaine or ropivacaine, etc.) with electronic analgesic pumping infusion; or multiple single injections of regular local anesthetics should be used to maintain the continuity of nerve block effect.
1.33% bupivacaine liposome
Ultrasound-guided nerve block
Experimental: Intravenous infusion of lidocaine + standard anesthesia protocol
(described in detail in sub-trial protocol 2)
  1. Subjects randomly assigned to Lidocaine Group (Group L) will be given ECG monitoring, oxygen saturation monitoring, blood pressure monitoring and an open intravenous route on the morning of the surgery. It is recommended to start the infusion of Lidocaine as soon as possible in the ward.
  2. It is recommended to use portable electronic infusion pump for drug delivery. The loading dose is 1mg/kg, and the maintenance dose range is 1~2mg/kg/h. The specific dosage is determined by the anesthesiologist based on the patient's condition. The infusion ends when the patient leaves the Post-anesthesia care unit after surgery, and the infusion time and total amount should be recorded.
No Intervention: Standard anesthesia protocol
(If an intervention was found to be effective in the interim analysis, the executive committee will decide whether to add it to the standard anesthesia protocol.)
