You can opt to have UAL under a local or a general anaesthetic, a general anaesthetic being used more commonly when more surgery is being performed at the same time as liposuction.  Ultrasonic-assisted Liposuction makes use of Tumescent injections to the area being treated before surgery.  This ensures the ease of fat removal and prepares the area so that there is less disruption to other surrounding tissues.  The injections contain a mixture of fluids such as a local anaesthetic and Epinephrine that will tighten the blood vessels to cut down on unnecessary bleeding. 

Small incisions, of about 4mm, are made in order to insert the cannula with the ultrasonic attachment, and then the fat cells are broken up using ultrasonic energy.  The cannula removes the cells as they are liquefied.  Often once the fat cells have been removed you won’t need your incisions sutured, the size of them allowing a sterile dressing instead. 

The process can take 30 minutes to 2 hours depending on the extent of your surgery.  If you are undergoing other surgery at the same time and opt for a general anaesthetic then you will be hospitalized for up to 2 days, if having a local anaesthetic then you will be free to go home up to a few hours after your UAL.
