At the end of every cardiac procedure, two or three chest tubes (28F–32F) are typically placed in the mediastinum to continuously monitor postoperative blood loss and to prevent undesirable blood collection, especially in the pericardial space, which could potentially lead to cardiac tamponade. The chest tubes are connected to various drainage systems that use the underwater valve seal principle. Suction of about –20 cm H2O is usually applied.
Here we present an alternative drainage system that provides distinct advantages over the commonly used systems.
Technique
The drainage system consists of four or five Redon (B. Braun Melsungen AG, Melsungen, Germany) drains (2-mm inner diameter). Each drain is connected to a 600-mL reservoir with an applied suction of –800 mbar (816 cm H2O) (Figure 1). They are placed into the pericardial space (and pleural cavity, if needed) in the following sequence (Figure 2):
