The risk associated with rapid intravenous administration of propofol is cardiovascular collapse. Propofol is a sedative-hypnotic agent that is commonly used for induction and maintenance of anesthesia. Rapid administration can lead to a significant decrease in systemic vascular resistance and cardiac output, resulting in hypotension and, in severe cases, cardiovascular collapse. This effect is particularly pronounced in patients who are already compromised or in those with pre-existing cardiovascular conditions.

In contrast, cerebral edema is not directly related to the administration speed of propofol, and respiratory infection is not a typical risk associated with this medication. Prolonged sedation may occur with higher doses or in sensitive populations, but it is not specifically linked to the speed of administration. Therefore, the cardiovascular concerns that arise from rapid propofol injection underscore the importance of careful and controlled administration in clinical settings.
