What will be a reason someone can go into cardiac arrest while getting a BBL?

Thank you for your question. This can be due to coronary artery disease or blockage of the blood vessels supplying the heart. I would advise you to schedule a consultation with a board certified plastic surgeon for a detailed examination to discuss all possible treatment options and what your expectations are.  

Everything is balancing risks and complications with result.  It is possible to get a fatal pulmonary embolus or a fat embolus.  It is also possible to have lidocaine toxicity or puncture an internal organ.  The risk of all of these is much less than 1% if you are healthy.
For your own safety, the board certified plastic surgeon you select should know everything about your past medical and surgical history and be able to make a determination about what labs should be ordered, the need for EKG, the need for medical clearance, the need for anticoagulation, the appropriateness of the surgical intervention based upon the risk factors and current physique, etc. The day of surgery, a hemoglobin, glucose, and pregnancy test are performed. 

Thank you for your question.There are many different things that could cause this problem to occur. Before surgery, testing is required based on your age to make sure you are healthy to undergo the procedure. In many cases, patients are required to have an EKG and chest x-rays done along with blood work. The requirements are also based on your medical and family history. I would discuss your medical history in depth with your surgeon, then based on that they can order the appropriate testing to make sure you are healthy to undergo anesthesia.

Dear Peaceful249,
every surgery has a possibility of complication. When performed correctly, the risk of major complications such as heart attack is very low. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

There are two ways the heart would go into arrest during surgery. The first one is due to coronary artery disease or blockage of the blood vessels supplying the heart. This is what happens during a heart attack. The heart doesn’t get enough oxygen and becomes ischemic. The second is in situations where the body is seriously under perfused because of a state of shock. During surgery this could happen from massive blood loss or under fluid resuscitation. This causes acid level that worsens with the release of intracellular potassium that eventually stop the heart. Cardiac arrest during surgery is not the problem but the end symptom. By the time someone arrests during surgery they are many other things that have gone wrong that represent the primary problem. These could have to do with things like having way too much surgery scheduled during a single procedure.Board certified plastic surgeons have a minimum of 10 years of medical training and sometimes more. This includes doing rotations in trauma surgery, critical care management, general surgery etc. etc. Many of us have done rotations in heart surgery.If you’re in the hands of a well trained physician who has experience and good clinical judgment the chance of serious complications area rare.The most serious complication that actually happens from a BBL is called a fat embolism. The consequence of this is often pulmonary failure leading to death. Eventually the heart stops but it is secondary to pulmonary failure. The incidence of fat embolism from a BBL has been described as being one in 3000. Currently most plastic surgeons take safety precautions to minimize the chance of this happening.Best, Mats Hagstrom MD
