How common is Hypovolemic shock during or after Liposuction of the abdomen of a fit person 5"11 140 pounds?

The short answer is uncommon to the point that I have not seen it in my practice of 20 years or heard of this happening in my community.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 yielded red fluid or blood with fat.If your complication was truly hypovolemic shock and not a parasympathetic event then the cannula may have directly tore a large vessel in the subcutaneous tissue like the superficial inferior epigastric vessels other periumbilical vessels.

Thank you for your question. The condition of hypovolemic shock after liposuction alone is exceedingly rare. The limits of the amount of fluid that we can deliver prior to the liposuction (called tumescent), and what can safely be removed with the selection process has been very well studied. Board-certified plastic surgeons are well aware of what he recommended limits are, and there are position papers published on this topic. As long as we stay under these amounts, that would be an extremely uncommon complication in an otherwise healthy patient. 

Hypovolemic shock is extremely rare when a patient is properly monitored and hydrated during the procedure.
