The use of anaesthesia can pose extreme risks in any surgical procedure, including cosmetic surgery. Although there are Liposuction techniques that do not require any kind of anaesthesia, the most frequently employed ones do. While local anaesthesia is both safer and more widely used than general anaesthesia, it nevertheless carries serious risks. Lidocaine toxicity, once a frequent problem often resulting in death, is very rare today. While there have been few deaths related to Lidocaine toxicity, there is nevertheless a risk involved even with the mildest form of anaesthesia. General anaesthesia, where the patient is unconscious during a medical or cosmetic surgery procedure, is the riskier option of the two. When a surgeon performs a procedure with the patient under general anaesthesia, the presence of a certified and trained anaesthesiologist is absolutely crucial for the patient's safety. Even so, one adverse reaction to anaesthesia is blood clotting whereby a clot can form and subsequently travel to the lung or the heart, with fatal results. The chance of blood clots forming is much higher with the use of general anaesthesia than local anaesthesia.
