Hypovolemic shock is extremely rare, yet an extremely serious complication. The amount of fat removed with liposuction as well as the amount of bleeding associated with the process are determinants of the risk of hypovolemic shock. You should make sure your surgery is being done by a well trained surgeon ( Diplomat of the American Board of Plastic Surgery ) and is being done in a safe environment (certified operating room) with appropriate monitoring. These are all important points to discuss with your surgeon prior to scheduling surgery. For the most part, liposuction is a very safe procedure when done carefully.
Hypovolemic shock is a very serious condition. This is extremely uncommon to see during or after a liposuction procedure. An experienced surgeon will have the patient properly prepared before the surgery and will ensure that the patient is monitored appropriately during the procedure. The surgeon should know how much fat can be removed safely for each specific patient. It is recommended that if there is more than 5000 cc of fat removed, the patient should stay overnight in a 23 hour facility to be monitored. Discuss this with your surgeon.
