The type of drainage systems employed typically consist of closed suction drains or open gravity drains. We aim to: 1. Queried leading surgical textbooks to find any description of how to remove a drain off-suction; 2. Designed an ex-vivo wound drain model to determine how efficiently a suction drain can be used for passive gravity-dependent drainage; 3. Describe a novel method to convert a closed-system suction drain to a highly-efficient closed-system gravity-dependent drain. METHODS: We reviewed the 5 top-selling urology and surgery test/reference books for information on drainage systems. An ex-vivo model was designed with a reservoir of fluid connected to a Jackson-Pratt bulb drain. We measured the volume of fluid drained from the reservoir into the bulb while on-suction and off-suction. This was repeated using a novel modified bulb, where the bulb’s outflow stopper was replaced with a one-way valve oriented to allow release of pressure from the bulb. RESULTS: No urology or surgery textbooks describe how to achieve passive closed-system wound drainage. Benchtop studies: With the bulb on-suction, drainage was maintained regardless of the height of the drain relative to the reservoir. With the bulb off-suction, closed passive gravity-dependent drainage occurred only when the drain was below the fluid reservoir, but always stopped after 5-7 cc drainage. With addition of a one-way valve and maintenance of the bulb below the level of the reservoir, drainage proceeded to completion (Video demonstration is provided). CONCLUSIONS: How surgical drains work is not described in the leading urology and general surgery textbooks/reference books. Closed-system suction drains cannot be used to achieve passive gravity-dependent drainage without allowing release of air (displaced by drainage inflow) from the bulb-lumen. The novel modified drain we describe affords reversible closed-system suction and passive drainage.
