Learning Curve of Ultrasound-Guided Suprainguinal Fascia Iliaca Block: A Prospective Observational Study

Compared to other nerve localization techniques, the benefits of UGRA include higher nerve block success rates, faster onset times, reduced local anesthetic volumes, and a lower risk of local anesthetic-related complications. Most experts now consider ultrasound guidance as the standard of care for peripheral nerve blocks. Successfully performing a UGRA procedure requires a triad of three distinct but interrelated skills: image acquisition, anatomical interpretation, and hand-eye coordination.

In our clinic, we routinely perform various nerve block techniques under ultrasound guidance during the perioperative period, both for postoperative analgesia and as a primary anesthetic method. Specifically, in our clinic, the suprainguinal fascia iliaca block (SIFIB) is routinely applied for postoperative analgesia, particularly in orthopedic cases. Before performing a nerve block procedure, resident doctors in our clinic undergo standard training and subsequently perform blocks under the supervision and support of experienced specialists and academicians.
