DRAINS
What kind of drain you need and which size ?The drain should be :Soft to avoid tissue injury .Non-irritating . Firm….incompressible .Resistant to decomposition .Smooth for easy removal .The Perfect Product
Greater tissue contact Inert material. Slides smoothly past any tissue Promotes ease of movement and deep breathing Minimal pain on removal Comes in various sizesDrain material
Latex rubber ( red rubber)…soft , but excites a profound inflammatory reaction within 24 H. .Polyvinyl chloride (PVC) …less reactive and incompressible , however , tend to harden and splite with prolonged use, especially when in contact with bile .Silicon ( best drain material ) least reactive and the most pliable, and show no tendency to harden with prolonged use .Drainage systems
Open ( static) drainage ;Penrose , multitubular ,corrugateClosed siphon drainage :Closed suction drainage :Low negative-pressure ( -100 to –150 mmHg ) e,g, Portovac , Reliavac .High negative-pressure ( -300 to –500 mmHg )e,g. Redivac , .Sump suction drainage : for irritant discharge .Underwater seal drainage .Type of Drains
