Hi there-
The prevention of blood clot formation after surgery can be divided into things your surgeon, nurse, and anesthesiologist should do, and things you can do.
The best and simplest way to be sure everything is being done to maximize your safety is to be sure the procedure is being performed by a surgeon certified by The American Board of Plastic Surgery (there are many "boards"- be sure you check!), and that the procedure will be performed in a facility accredited by a national organization such as the American Association for the Accreditation of Ambulatory Surgical Facilities (AAAASF). These regulatory bodies require frequent inspections of the facility's safety procedures, protocols, and equipment, as well as the staff's training in their use and implementation. In other words, ask about your surgeon's credentials, those of the facility where the procedure will be performed, and also those of the anesthesiologist.
Most people I meet do realize they should ask a lot of questions about the surgeon they choose, but most don't realize that the quality (or lack thereof) of the facility and the anesthesiologist are almost as important to minimizing risks and maximizing safety.
Be your own best advocate-
