Although there has been an increase in the use of lumbar plexus block (LPB), the technique may be time consuming and associated with complications. Suprainguinal fascia iliaca compartment block (FICB) is a potentially easier and safer alternative. The current study prospectively compares LPB with suprainguinal FICB.Methods: This prospective, double-blinded, randomized, study included patients undergoing elective orthopedic procedures of the hip and/or femur. All study patients received general anesthesia with randomization to either an LPB or suprainguinal FICB using 0.5% ropivacaine with epinephrine and dexamethasone. Postoperative pain control was achieved with intravenous hydromorphone delivered by patient-controlled analgesia with scheduled acetaminophen and ketorolac. Outcome data included time to perform the block, perioperative opioid consumption, postoperative pain scores (VAS) and hospital length of stay.Results: The study cohort included 15 patients between the ages of 7 and 16 years (LPB N = 7, FICB N = 8). The median block time was 6 minutes (IQR: 4.11) for the LPB group and 3 minutes (IQR: 3.6) for the FICB group (p = 0.107). Median postoperative pain scores were 4 (IQR: 0.6) for the LPB group and 2 (IQR: 0.5) for the FICB group (p = 0.032). There were no differences in the intraoperative or postoperative opioid and NSAID use between the two groups.Discussion: The suprainguinal FICB provides analgesia that is at least as effective as a LPB following hip and femur surgery. Time to perform the block was shorter with the FICB due to the supine patient position and limited needle trajectory. Although we noted no adverse effects, the superficial needle trajectory of the FICB offers a less invasive approach and the potential for decreased risks of adverse effects.Keywords: orthopedic surgery, postoperative analgesia, lumbar plexus block, suprainguinal fascia iliaca block
