We have been safely performing liposculpture under tumescent local anaesthetic in our clinic procedure rooms for 10 years now without any significant complications. In my opinion the key to safe liposculpture (apart from good general technique principles) is to limit the number of tissue regions (and the amount of fat to be removed) in any one session. One should not test the limits of a patient’s safe physiologic function with excessive liposculpting treatment and avoid combining liposculpture with other operations in the one session.
As is the case in many other cosmetic procedures, pleasing and safe outcomes are founded on the avoidance of overly agressive surgery.
An Australian colleagues gives an excellent summary on Liposculpture on his website and I link to it here: http://www.facialartistry.com.au/liposuction-tumescent_liposuction.html
