Which complication is associated with Propofol infusion syndrome?

• A. Hyperglycemia
• B. Metabolic acidosis
• C. Hypertension
• D. Bradycardia

Answer: (B)

Propofol infusion syndrome is a serious condition that can occur following prolonged administration of propofol, particularly in patients receiving high-dose infusions. This syndrome is characterized by various metabolic derangements, one of the most significant being metabolic acidosis. The underlying mechanisms involve mitochondrial dysfunction and impaired fatty acid oxidation, leading to a buildup of lactate, which contributes to the development of acidosis. While hyperglycemia, hypertension, and bradycardia can each be associated with various clinical conditions or drug interactions, they are not core features of propofol infusion syndrome. In particular, bradycardia can occur as a result of other anesthetic or surgical complications, and while hyperglycemia may arise in critically ill patients, it is not specifically linked to the syndrome. Hypertension can also be influenced by various factors in a clinical setting but does not relate directly to the pathophysiology of propofol infusion syndrome. Thus, metabolic acidosis is the hallmark of this syndrome, making it the correct choice in this context.
