Brief summary

Anesthesia and perioperative Neurocognitive Disorders in the Elderly patients undergoing hip fracture Surgery platform trial (ANDES platform trial): A pragmatic multi-arm, adaptive, open label, multicenter randomized controlled platform trial to assess the effect of different enhance anesthesia technique in perioperative neurocognitive function, as compared to standard anesthesia care in the elderly patients undergoing hip fracture

Interventions

OTHERNerve block+standard anesthesia

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.

DRUGIntravenous lidocaine+standard anesthesia

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.

Inclusion criteria

1. Aged 65 years and older. 2. Patients with unilateral hip fracture (including femoral neck, femoral head, intertrochanteric and subtrochanteric fractures) are scheduled for surgical treatment. 3. American Society of Anesthesiologists (ASA) physical status IV or below. 4. The patients or family members provide written informed consent. 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.); 4. Patients who the researcher believes are unable to complete the assessment of primary outcome; 5. Additional

Design outcomes

Primary

MeasureTime frameDescription
Incidence of Neurocognitive Disorders (NCD) events rate during the first 7 postoperative daysduring the first 7 postoperative daysNeurocognitive Disorders includes: 1. Postoperative delirium (POD) was mesaured by 3D-CAM; 2. Neurocognitive decline was mesaured within 7 postoperative days by: Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA), and neuropsychological tests containing 5 cognitive latitudes (1. digit span test (DST); 2. trail making test (TMT); 3. Boston naming test (BNT); 4. auditory verbal learning test-Huashan version (AVLT-H);5. clock drawing test (CDT).), and active report of patients or family members).

Secondary

MeasureTime frameDescription
Subtypes, severity, and duration of deliriumduring the first 7 postoperative daysUsing CAM-S, and in units of days from the onset of delirium symptoms to the disappearance of symptoms or when the patient is discharged.
Neurocognitive decline in postoperative 7 daysduring the first 7 postoperative daysNeurocognitive decline was mesaured by: Mini-Mental State Examination (MMSE) or Montreal Cognitive Assessment (MoCA), or neuropsychological tests containing 5 cognitive latitudes (1. digit span test (DST); 2. trail making test (TMT); 3. Boston naming test (BNT); 4. auditory verbal learning test-Huashan version (AVLT-H);5. clock drawing test (CDT).), or active report of patients or family members.
Delayed neurocognitive recovery during 30 postoperative daysduring 30 postoperative daysThis was mesaured by: Mini-Mental State Examination (MMSE) or Montreal Cognitive Assessment (MoCA), or neuropsychological tests containing 5 cognitive latitudes (1. digit span test (DST); 2. trail making test (TMT); 3. Boston naming test (BNT); 4. auditory verbal learning test-Huashan version (AVLT-H);5. clock drawing test (CDT).), or active report of patients or family members.

Mortality30 days
Score of EuroQol Five Dimensions Questionnaire (EQ-5D)1 week before fracture (review); 1 month; 6 months; and 12 months after surgery.using EQ-5D to measure quality of life
Incidence of postoperative Neurocognitive Disorders (NCD)within 1 year after surgery (long-term)This was mesaured within 7 postoperative days by: Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA), and neuropsychological tests containing 5 cognitive latitudes (1. digit span test (DST); 2. trail making test (TMT); 3.
