- Drain insertion into a wound is standard if a large amount of drainage is expected
- Drains prevent fluid build up in the tissues which would slow healing and increase infection risk.
- Drains may be sutured in place to maintain placement and integrity
- Caution used upon changing wound dressings surrounding a drain site
The Penrose drain
A soft rubber tube placed in a wound area, to prevent the build up of fluid.
- This is the most commonly used drain
- Made of flexible, soft rubber and causes little tissue reaction.
- Acts by drawing any pus of fluid along its surfaces through the incision or through a stab wound adjacent to the main incision.
- It has a large safety-pin outside the wound to maintain its position
- To Facilitate drainage and healing of tissues from the inside to the outside, the tube is often pulled out and shortened 1-2 inches each day until it falls out.
- The safety-pin should be placed in its new position prior to cutting the drain
- Advance the drain with dressing forceps or hemostat, use surgical scissors to cut excess drain.
- Note drainage amount and colour appearing in collection apparatus
The Jackson-Pratt, JP drain, or Bulb drain (Hemovac)
- Consists of a flexible plastic bulb that connects to an internal plastic drainage tube
- Device used to pull excess fluid from the body by constant suction.
- Removing the plug and squeezing the bulb removes air
- This is usually accomplished by folding the drain in half while it is uncapped, then while folded, recapping the drain.
