Ultrasound-Guided Femoral and Sciatic Nerve Blocks in an Anticoagulated Patient. Case Reports

Abstract

Anticoagulation imposes some restrictions to classical regional anesthetic techniques. With the development of ultrasound equipment and methods, it is now possible to accurately identify vascular and neural structures. This allows ultrasound-guided puncture to be more precise, both to achieve the area of interest and to minimize the risks of accidental vascular damage. Until now, peripheral block was not recommended in anticoagulated patients or in those with coagulopathies. However, considering that few reports on ultrasound-guided regional blocks in coagulopathies can be found in the literature, the safety of this technique in this condition has yet to be established.
