title: VariDyne--new standards in postoperative wound drainage.
abstract: Conventional wound drainage systems operate at the beginning of the drainage procedure with a unilateral pressure of -0.9 bar. The system becomes static in case of no or only little secretion per unit of time. The pressure which is then unphysiologically high influences the microcirculation of the wound edge. A dynamic source of low pressure, which can be adapted to the individual requirements by varying its pressure, is coming from America.
