What are the symptoms associated with Propofol-Related Infusion Syndrome (PRIS)?

• A. Decreased blood pressure and hypotension
• B. Bradycardia and increased cardiac output
• C. Hyperkalemia and ECG changes
• D. Excessive sedation and respiratory depression

Answer: (C)

Propofol-Related Infusion Syndrome (PRIS) is a serious condition that can occur with prolonged administration of propofol, particularly at high doses, and is characterized by a distinct set of symptoms. The symptoms associated with PRIS include hyperkalemia, which is an elevated level of potassium in the blood, and associated ECG changes that may manifest as dysrhythmias or changes in the cardiac conduction system. The elevation in potassium can lead to significant cardiovascular complications. Patients with PRIS may also experience metabolic acidosis, rhabdomyolysis, and acute renal failure, but the hyperkalemia and its ECG changes are particularly characteristic of the syndrome. Understanding these symptoms is crucial for early recognition and intervention, making hyperkalemia and ECG changes a key focus when monitoring patients receiving propofol infusions. The other options describe symptoms or conditions that are not typically associated with PRIS or are not specific to it. For example, decreased blood pressure and hypotension can occur with various medications but are not uniquely indicative of PRIS. Bradycardia and increased cardiac output do not align with the typical presentation of PRIS. Excessive sedation and respiratory depression can be side effects of propofol but do not encapsulate the unique and
