General anesthesia is never needed for liposuction. General anesthesia adds unneeded risk to liposuction. GA (general anesthesia) increases the risk of post op nausea and vomiting. You don't want to be throwing up for 24 hours after your Lipo.
Most extensive lipos require either placing the patient face down on their stomach and/or turning the patient from side to side. There is more risk when patients are moved when they are asleep under GA than when they are awake.
Tumescent anesthesia is a specialized local anesthesia that was developed in the 1980's to allow surgeons to perform lipo without the risks of GA. A very dilute solution of local anesthetic and adrenaline is injected into the fat. This accomplishes two things; you feel no pain and there is almost no bleeding. Every lipo should have Tumescent fluid injected into the fat! Even when general anesthesia is used! The adrenaline prevents excessive blood loss and is one of the reasons Lipo has such a great safety record.
Why IV Sedation?
Unless the Tumescent (local anesthesia) is injected very, very slowly, it burns and hurts when it goes in. The sedation is used so that the patient won't feel the discomfort associated with injecting the local. The downside is some doctors give so much IV sedation, the patient is really getting GA (general anesthesia) through their vein. That is a dangerous situation if not monitored by an anesthesiologist or a CRNA (certified registered nurse anesthetist).
Very few facilities use pure local without some sedation.
For more than 20 years, we have combined epidural anesthesia ( the very safe anesthesia used for child birth ), Tumescent local, and light sedation.
Be sure any cosmetic surgery that you undergo is performed in a state licensed and national accredited facility under the supervision of an anesthesiologist or a nurse anesthetist.
Safety is your prime concern!
