Discovered in 1977, Propofol is a medication used to put patients to sleep and keep them asleep during general anesthesia for surgery or other medical procedures. Besides, it is used to sedate a patient who is under critical care and needs a mechanical ventilator (breathing machine). Propofol is also used for status epilepticus if other medications have not worked. What this drug basically does is decrease the activity of the brain and nervous system. Bear in mind that it is vital that your stomach is empty prior to elective surgery and anesthesia. Once you’re anesthetized, your cough reflex and gag reflex are abolished. These reflexes prevent food or liquids from entering your windpipe or your lungs, and are life-protecting reflexes in awake, healthy humans. It is worth noting that Propofol can cause an irregular heart rate, low blood pressure, burning sensation at the site of injection, and the stopping of breathing. As for its serious side effects, they may include seizures, infections with improper use, and addiction. Fortunately, Propofol appears to be safe to use during pregnancy.
