Anesthetic concerns in patients presenting with renal failure.

Anesthesiologists often care for patients with renal insufficiency or renal failure. These patients may present to the operating room for a minor procedure such as an inguinal hernia repair or an arteriovenous fistula/graft. Alternatively, they may present for major abdominal operations or coronary artery bypass grafting. Critically ill patients presenting to the operating room may have acute kidney injury. It is imperative that the anesthesiologist understands the ramifications of renal failure and adjusts the anesthetic plan accordingly. Hemodynamic monitoring and fluid management can be challenging in this patient population. Various metabolic abnormalities can ensue that the anesthesiologist must be able to manage in the acute setting of the operating room. (c) 2010 Elsevier Inc. All rights reserved.
