**2.1 Anaesthesia**

Loco-regional anaesthesia is commonly used with injection of Klein' Solution, (**Figure 1**). One litre of normal saline is mixed with 50 cc of 1% plain Lidocaine, 1 ml of 1:1000 epinephrine and 10 cc of physiological concentration of Sodium bicarbonate to reduce the acidity and therefore reduce the discomfort of injection.

In conventional liposuction the fat is not preserved, conversely, in fat transfer or in FAMI it is necessary to use a very conservative method similar to a biopsy in order to preserve intact the fat cylinders inside the 10 cc syringe.
