How common is blood loss or fluid loss during abdominal lipo under local anesthesia, awake?

Blood loss has not been an issue with liposuction after the tumescent technique was developed about 20 years ago.  The tumescent technique involves infiltrating a fluid within the tissues that has epinephrine in it.  This causes the vessels to constrict so much that the fat that comes out through the tubing is yellow while the old technique yield red or blood with fat.In your case the cannula may have directly tore a large vessel in the tissues. This would eventually cause dark bruising and swelling.

Blood loss should be very minimal assuming your surgeon uses a solution to minimize bleeding and is skilled at doing the procedure.  Plastic surgeons would typically always use this. I would ensure that you are seeing a plastic surgeon for your liposuction and not some other form of "cosmetic surgeon" that actually is not trained as a plastic surgeon.Dr Rodger ShorttOakville Plastic SurgeonAssistant Clinical Professor &Director of Cosmetic Surgery Training,McMaster University

Thanks for the question. Blood loss is very minimal during liposuction. It is uncommon using the tumescent technique.
