NYSORA – fascia-iliaca block
The New York School of Regional Anaesthesia describe a different approach to the fascia-illiacs block than that described by Neuraxiom.
The NYSORA approach places the transducer parallel to the inguinal ligament and the block is performed in-plane.
Compared to performing the block with the probe perpendicular to the inguinal ligament, this places the injection further distally. However, the major limitation of the Neuraxiom approach occurs in obese patient when the abdomen interferes with positioning of the probe. The NYSORA approach can be used to get around this problem by placing the probe further distally. Whether you use this method routinely or not, it is useful to be familiar with both techniques.
