Self-transfusion represents a clinical method used for the restoration of haematic losses that, in recent years has been employed more and more widely in the surgical ambit. The utilisation of this method has become increasingly frequent because of the high diffusion of haemotransmitted diseases, and of the incidences, not negligible, of complications relative to the transfusions of homologous blood. The techniques that are currently used are: self-donation with predeposit; inter-surgery recovery; hemodilution normal blood volume. From 1989 until now 260 patients have been performed, in the Institute of III Surgical Clinic of University of Rome, to self-transfusional method with predeposit and intersurgery recovery. In practice this technique did not present any complications.
