 Drainage Surgical Suction Devices Surgical drains are implants that allow the removal of fluid or gas from a wound or body cavity. These drains are used in various types of surgeries like plastic surgery, orthopedic procedures, chest surgery, gastrointestinal surgeries, neuro surgery, etc. Surgical drains are widely used to prevent the accumulation of fluid-like blood, pus and infected fluids and prevent accumulation of air. Drain can help the healing process by removing inflammatory mediators, bacteria, foreign material and necrotic tissues. They enable monitoring for potential complications by allowing easy sampling of fluid during healing. The main indications of drain use include the need to eliminate dead space, remove existing fluid or gas and prevent accumulation of fluid or gas. While active drains are maintained under suction, passive drains have no suction and work according to the differential pressure between body carities and the exterior. Generally, drains are removed once the drainage has stopped.
