Which condition is a concern for hepatic disease under anesthesia?

• A. Hypoproteinemia
• B. Hyperglycemia
• C. Hyperkalemia
• D. Hypocalcemia

Answer: (A)

The main concept is how liver disease alters anesthesia by reducing protein production and drug metabolism. In hepatic disease, albumin synthesis drops, causing hypoproteinemia. Albumin is the primary protein that binds many anesthetic drugs. When albumin levels fall, there’s less binding and a higher fraction of free, active drug in the circulation. This can enhance and prolong the effects of these medications, and since liver function is also impaired, drug clearance slows further, increasing the risk of prolonged sedation or toxicity during and after anesthesia. In practice, this means agents that are highly protein-bound and largely metabolized by the liver will have exaggerated effects and slower recovery in someone with liver disease. Hyperglycemia is not the characteristic concern of hepatic disease in this context ( severe liver failure more often predisposes to hypoglycemia due to impaired gluconeogenesis). Hyperkalemia and hypocalcemia are not specifically tied to hepatic dysfunction as the primary anesthetic concern. So, hypoproteinemia best explains the hepatic disease-related anesthesia concern.
