With the major advances in cosmetic surgery over the last twenty years, Liposuction is generally reputed to be a safe and relatively painless method of body contouring. However, as with all surgical procedures there are risks involved. These range from small-scale anticipated reactions such as bruising and temporary skin asymmetry to more serious complications like scarring, haematomas, and Lidocaine Toxicity. In addition, different Liposuction techniques will put the patient at risk of different reactions. The Ultrasonic-Assisted Liposuction technique, for example, has been known to cause seromas on occasion. Seromas are small pockets of clear fluid which form underneath the skin, often as a result of too much fat being removed from the body in a short period of time. The formation of seromas is the body's way to compensate for lost fluids. Although seromas can be easily drained with a syringe, neglecting to seek treatment quickly can lead to infection.

With the Tumescent Technique the most popular method for removing excess fat, the Dry Technique is virtually non-existent in today's cosmetic surgery market. Why was the Dry Technique ruled out as a safe option? It provided no insulation and no medications to prevent the patient from losing significant amounts of blood. Patients were often admitted directly after surgery, frequently required blood transfusions and suffered from haematomas. Haematomas are essentially seromas, but are formed by trapped blood rather than serum. The Tumescent Technique has virtually ruled out the possibility of haematomas, thanks to the administration of the vasoconstricting drug Adrenaline.
