About this study

Official title: Fascia Iliaca Block Using Liposomal Bupivacaine for Analgesia After Hip Surgery: a Randomized Trial

Patients after hip surgery often suffer from severe pain. Inadequate analgesia increases the risk of postoperative delirium, myocardial injury, and other complications. Peripheral nerve block is an important component of multimodal analgesia, but conventional local anesthetics (such as plain bupivacaine) provide only approximately 12 hours of analgesic duration, which is far from covering the most painful 72 hours after surgery. Liposomal bupivacaine has a slow-release property, prolonging the analgesic duration up to 72 hours after a single injection. However, its clinical advantages in hip fracture surgery remain controversial. The investigators suppose that, compared with plain bupivacaine alone, preoperative supra-inguinal fascia iliaca block using liposomal bupivacaine combined with plain bupivacaine can further improve analgesia, decrease opioid consumption, and improve postoperative recovery quality within 72 hours in older patients after hip fracture surgery.

Read the detailed description

Hip joint diseases are among the major disorders that impair patients' motor function and quality of life. With the acceleration of population aging and the advancement of hip reconstruction techniques, the number of patients undergoing hip arthroplasty has continued to increase. Hip arthroplasty primarily includes hemiarthroplasty and total hip arthroplasty (THA), with indications covering a variety of diseases and injuries, including osteonecrosis of the femoral head, hip osteoarthritis, ankylosing spondylitis, developmental dysplasia of the hip, and other conditions that lead to structural destruction and functional impairment of the hip joint. Hip arthroplasty can effectively relieve pain, improve joint function, and enhance patients' quality of life, and has become an important treatment modality for end-stage hip joint diseases.

Optimizing analgesia through multimodal strategies can enhance postoperative recovery and shorten hospital stays. Peripheral nerve blocks (PNB), particularly ultrasound-guided femoral nerve block or supra-inguinal fascia iliaca compartment block (FICB), have been shown to reduce pain and opioid consumption after hip surgery. A recent prospective cohort study indicated that better perioperative pain control with PNB is associated with lower opioid needs and shorter hospitalization.

Conventional local anesthetics like ropivacaine or bupivacaine provide analgesia for about 12 hours, which is insufficient for the entire perioperative period. Liposomal bupivacaine, an extended-release formulation, can provide analgesia for up to 72 hours. Some studies have demonstrated benefits of liposomal bupivacaine for nerve blocks in thoracic and hip surgeries, including improved recovery quality, reduced opioid use, and lower pain scores at 24-72 hours. However, evidence remains controversial; several meta-analyses suggest that while statistical differences exist, clinical relevance may be limited.

Inadequate pain control negatively affects postoperative outcomes and is associated with delirium, myocardial injury, and pulmonary complications-especially in vulnerable older patients with reduced physiological reserve and multiple comorbidities. Therefore, this randomized controlled trial aims to investigate whether preoperative FICB using liposomal bupivacaine combined with plain bupivacaine can provide superior perioperative analgesia compared with plain bupivacaine alone in older (≥55 years) patients undergoing hip fracture surgery.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Liposomal bupivacaine (LB)Drug

    A single preoperative ultrasound-guided supra-inguinal fascia iliaca block will be perfomed using a mixture of 10 mL of 0.5% plain bupivacaine plus 20 mL of liposomal bupivacaine (266 mg), total volume 30 mL. The injection will be performed after negative aspiration and under real-time ultrasound visualization to ensure proper spread between the fascia iliaca and the iliacus muscle. The block will be performed in the preoperative holding area.

  • Plain bupivacaineDrug

    A single preoperative ultrasound-guided supra-inguinal fascia iliaca block will be performed using 30 mL of 0.5% plain bupivacaine (150 mg). The injection will be performed after negative aspiration and under real-time ultrasound visualization to ensure proper spread between the fascia iliaca and the iliacus muscle. The block will be performed in the preoperative holding area.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The area under curve of pain intensity within 72 hours after surgery

    Pain intentsity will be assessed with the numeric rating scale (NRS; an 11-point where 0=no pain and 10=the worst pain) at 2, 6, 12 hours and then very 12 hours, until 72 hours after surgey. The area under curve of pain intensity will be calculated using the trapezoidal rule.

    Measured: Up to 72 hours after the surgery

Secondary outcomes (2)
  1. Cumulative opioid consumption within 72 hours after surgery

    Cumulative opioid consumption will be calculated as intravenous morphine equivalent dosage.

    Measured: Up to 72 hours after the surgery

  2. Incidence of cardiovascular events within 7 days after surgery

    Cardiovascular events includes myocardial injury, non-fatal cardiac arrest, and all-cause death.

    Measured: Up to 7 days after surgery

On the ClinicalTrials.gov record for NCT07643792, which also lists 37 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Aug 2026.
