title: Effects of continuous fascia iliaca compartment blocks for postoperative analgesia in patients with hip fracture
abstract: Effective analgesia is essential for the postoperative care of orthopedic patients.
  
  
  
  To evaluate the efficacy of continuous fascia iliaca compartment block (FIB) as postoperative analgesia after hip fracture surgery, and to compare FIB with patient-controlled intravenous analgesia (PCIA) using fentanyl for 48 h postoperatively.
  
  
  
  Patients with hip fractures who were scheduled for open reduction and internal fixation surgery using the antirotation proximal femoral nail technique were randomly assigned to the FIB or PCIA groups. Postoperative pain was assessed using a numeral rating scale at 2 h, 4 h, 6 h, 12 h, 24 h and 48 h after analgesia was started. Delirium, postoperative nausea and vomiting (PONV), and pruritus were also monitored.
  
  
  
  Patients in the FIB group reported less pain than those in the PCIA group (P=0.039, d=-0.3). The change in pain scores over time was similar between the two groups. There were six patients with PONV and five patients with pruritus in the PCIA group, while no PONV or pruritus was noticed in the FIB group (P=0.013). Ten (19.6%) patients in the FIB group and three (5.7%) patients in the PCIA group developed postoperative delirium (P=0.032, d=0.77).
  
  
  
  Continuous FIB is a safe and effective technique for postoperative analgesia after hip fracture surgery, making it an option for pain management in elderly patients with hip fractures.
