title: Fascia iliaca block vs intravenous fentanyl as an analgesic technique before positioning for spinal anesthesia in patients undergoing surgery for femur fractures-a randomized trial.
abstract: OBJECTIVE
  Pain arising from femur fractures is of severe nature. Surgery for fixation of femoral fractures may be done under spinal anesthesia. We conducted this study to compare the analgesic efficacy of fascia iliaca compartment block (FICB) and intravenous fentanyl (IVF) before positioning for spinal anesthesia.
  
  
  METHODS
  Randomized controlled trial.
  
  
  METHODS
  Operating room.
  
  
  METHODS
  Sixty patients aged 25 to 75 years, with American Society of Anesthesiologists status I to III, undergoing surgery for femur fracture were chosen for the study and randomized into 2 groups. Patients in group FICB received the block with 30 mL of 0.375% ropivacaine 15 minutes before the subarachnoid block. Patients in group IVF received intravenous fentanyl at 0.5 μg/kg body weight repeated up to a maximum of 3 doses. Spinal was administered using 12 to 15 mg of 0.5% hyperbaric bupivacaine with glucose 80 mg/mL in patients of both groups.
  
  
  METHODS
  Preprocedural and postprocedural parameters such as visual analog scale (VAS) scores, sitting angle, quality of positioning, and time to perform the spinal were recorded. Patients were also assessed in the first 24 hours for analgesic requests.
  
  
  RESULTS
  Preprocedural VAS scores were similar in both groups. The "VAS after" was 24.72±15.70 mm in group FICB vs 61.22±18.18 mm in group IVF (P=.01). The drop in VAS scores was significantly more in the FICB group. Sitting angle improved significantly in the FICB group. (56.17°±16.54° vs 21.38°±23.90°; P=.01). Patients in group FICB also needed less time for spinal and had better quality of positioning. Postoperative analgesic requirement was lesser in group FICB.
  
  
  CONCLUSIONS
  Fascia iliaca block offers superior analgesia compared to IVF in patients with femur fracture before positioning for spinal anesthesia.
