Ultrasound-guided transversus abdominis plane/genitofemoral blocks for a patient receiving extracorporeal life...

Extracorporeal life support may be used in patients with refractory cardiogenic shock. The femoral venoarterial route can be used for implanting cannulae in patients who are hemodynamically unstable. Here we describe the use of an ultrasound-guided transversus abdominis plane block supplemented with the femoral component of the genitofemoral nerve as the anesthesia technique for peripheral cannulation of the femoral vessels in a patient with severe acute heart failure after myocardial infarction with ST-segment elevation. The procedure was performed using 40 mL of a 50:50 mixture of 0.5% levobupivacaine and 2% lidocaine (30 mL for transversus abdominis plane and 10 mL for genitofemoral block) associated with low-dose remifentanil infusion during spontaneous breathing. A left ventricular assist device was successfully implanted 4 days later.
