Fascia Iliaca Block Using Liposomal Bupivacaine for Analgesia After Hip Fracture Surgery

7 giugno 2026 aggiornato da: Dong-Xin Wang, Peking University First Hospital

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

Older patients with hip fractures 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 (e.g., 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 within 72 hours after surgery in older patients undergoing hip fracture surgery, decrease opioid consumption, and improve postoperative recovery quality.

Panoramica dello studio

Descrizione dettagliata

Hip fracture is a global health concern. Data from 204 countries over the past 30 years show an increasing incidence of hip fractures in people over 55 years old. With population aging, China is projected to have 1.3 million new geriatric hip fracture cases annually by 2050, imposing a heavy burden on individuals, families, and healthcare systems. Timely surgery remains the preferred treatment.

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 provides superior perioperative analgesia compared with plain bupivacaine in older (≥55 years) patients undergoing hip fracture surgery.

Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Sperimentale: Liposomal bupivacaine group
Participants in this arm will receive a single preoperative ultrasound-guided supra-inguinal fascia iliaca block. The mixture used for nerve block will consist of 10 mL of 0.5% plain bupivacaine plus 20 mL of liposomal bupivacaine (266 mg), for a total volume of 30 mL. The mixture will be injected after negative aspiration and under real-time ultrasound visualization to confirm correct needle tip position between the fascia iliaca and the iliacus muscle. The block is performed in the preoperative holding area.
