Diprivan, known generically as propofol, is an intravenous anesthesia drug used to sedate patients for surgery or for maintenance of sedation in intensive care patients 1. It is not recommended for children, but for adults only. The medication, according to RxList.com, is linked to failure of human organ systems that may kill a patient. This is called Propofol Infusion Syndrome.

Cardiovascular Effects

The use of propofol has been shown in clinical trials, according to RxList.com, to produce some problems in the cardiovascular system. Primarily, arrhythmia has resulted in some patients 2. Arrhythmia is a condition in which the heart either slows down—called bradycardia—or speeds up—tachycardia—or the heartbeat becomes irregular, according to the National Institutes of Health 2. Diprivan also has produced as a side effect hypertension—high blood pressure—and hypotension—low blood pressure—in some patients 1. Even more serious cardiovascular side effects may include myocardial ischemia, which involves a lack of blood flow to the heart, and heart attacks.
