Combined sciatic-psoas compartment nerve block in a patient with multiple myeloma

New techniques for the regional administration of anesthesia are being developed every day. Peripheral nerve blocks affect only minimally a patient’s hemodynamics, and may be the ideal choice in high-risk patients who may be intolerant to even a minor decrease in hemodynamic response. In this case report, the use of a combined sciatic-psoas compartment nerve block for a lower extremity surgery in a high-risk patient with multiple myeloma, acute renal failure and ASA III risk is addressed.
