Abstract：
:Four low-vacuum systems and 6 high-vacuum systems were examined concerning their pressure-volume relationships. For each type the maximum filling volume for sufficient drainage of wound secretions was determined. The use of a wound fluid substitute instead of water resulted in a lower aspiration volume. Enlargement of the tube diameter showed a reduction in the initial vacuum for the low-vacuum systems, whereas the high-vacuum systems were not affected. The amounts of postoperative wound fluid lost in selected ENT operations were determined. Considering the volume capacity of the wound drainage systems, the type of container can be chosen that eliminates the necessity for later bottle exchange on the wards, thus avoiding a potential risk for wound infection. The high-vacuum systems with a volume capacity of 150 or 200 ml are sufficient for parotidectomies, costal cartilage resections and reconstructions of the auricle, resulting in good postoperative wound adaptation and also preventing the need for postoperative bottle exchanges.
