It's a white, yellow, or brown fluid and might be slightly thick in texture. It's made up of white blood cells trying to fight the infection, plus the residue from any bacteria pushed out of the wound. There may be an unpleasant smell to the fluid, as well.
Normal wound drainage involves the discharge of thin, watery fluids that may be clear or contain tiny amounts of blood. Abnormal wound drainage is when the discharge is thick, bloody, or has a milky white, yellow, green, gray, or brown color (often with a foul smell).
Color is generally clear to pale yellow (normal), red (fresh blood), brown (dried or old blood), white (see above), or blue-green (usually indicative of Pseudomonas infection and should be cultured). The amount of drainage is generally documented as absent, scant, minimal, moderate, large, or copious.
Serous drainage is composed mainly of plasma. It is often thin and watery and will usually have a clear to yellowish or brownish appearance. Small amounts of serous drainage are normal during the first stages of healing.
Purulent drainage is thick, milky, and even changes colour if the infection progresses. Green, yellow, brown or white colour: A wound exhibiting purulence is plagued with pus – a sign of infection. If the pus appears to be green, yellow, brown or milky white in colour, it indicates a progression of infection.
Your surgeon will usually remove the bulb when drainage is below 25 ml per day for two days in a row. On average, JP drains can continue to drain for 1 to 5 weeks. Keep a log and bring it to the clinic for discussion so your surgical team can determine the best time to remove the drain.
Evidence indicates that if a wound is not allowed to drain freely, blood, body fluids, pus, and necrotic material will collect in the wound, providing a growth medium for microorganisms. Surgical wound drainage is recognized as a key element in facilitating the healing process.
Purulent drainage is a sign of infection. It's a white, yellow, or brown fluid and might be slightly thick in texture. It's made up of white blood cells trying to fight the infection, plus the residue from any bacteria pushed out of the wound. There may be an unpleasant smell to the fluid, as well.
Surgical drains are implants that allow removal of fluid and/or gas from a wound or body cavity. This broad definition includes nasogastric tubes, urinary catheters, vascular access ports, and ventriculoperitoneal shunts.
There are four types of wound drainage: serous, sanguineous, serosanguinous, and purulent. Serous drainage is clear, thin, and watery. The production of serous drainage is a typical response from the body during the normal inflammatory healing stage.
Moderate amount of drainage: Wound tissue is wet, and drainage covers 25% to 75% of the size of the bandage. Large or copious amount of drainage: Wound tissue is filled with fluid, and exudate covers more than 75% of the bandage.
Once you stop the bleeding and clean the wound, you should apply a clean bandage. Here's why: Air dries out the wound and promotes cell death, not healing. Covering the wound maintains the natural moisture that helps keep cells alive.
Drainage can be a sign of infection, but not always. The actual appearance of drainage will indicate if the wound is healing normally or if it requires further medical attention.
A wound that's healing can produce a clear or pink fluid. An infected wound can produce a yellowish, bad-smelling fluid called pus. When fluid seeps from a wound, it is called wound drainage.
Serous drainage is a clear, thin, and watery exudate that typically appears during the inflammatory stage of wound healing.
– Is drain removal painful? Patients may experience a pulling or pressure sensation, however there is generally no pain experienced during drain removal. Drain removal takes only a few seconds. The stitch securing the drain in place is first removed followed by gentle removal of the drainage tube.
How long it takes to heal a wound depends on how large or deep the cut is. It may take up to a few years to completely heal. An open wound may take longer to heal than a closed wound. According to Johns Hopkins Medicine, after about 3 months, most wounds are repaired.
Once the wound has formed a scab, there is no longer the need to cover it with a bandage as the scab now acts as a protective barrier. Keep the area clean, but be gentle so that you do not accidentally remove the scab.
Wound drainage is the result of the blood vessels dilating during the early stages of healing. This is possibly because certain bacteria are present at the time. Your body is creating a moist environment around the wound in an attempt to heal itself.
An abscess is a collection of pus. Pus is a thick fluid that usually contains white blood cells, dead tissue and germs (bacteria). The pus may be yellow or green and may have a bad smell.
Your wound may continue to drain a large amount over the next several days as the infection slowly heals. Wear a gauze dressing to the wound to protect your clothing. You may also use a sanitary napkin for further protection of your clothing. You may notice bloody discharge for the next four to seven days.
If wound is draining much, pack with dry gauze to absorb excess moisture. For copious drainage, sanitary pads can be a very absorbent, cushiony, and inexpensive dressing. Wound drainage may be clear, cloudy, pink, yellow, dark red, or brown. It should gradually become clearer, and be produced in smaller amounts.
Pus is a sign that a wound is infected but it is also a sign that your body is trying to fight the infection and heal the injury. Once an infection has started, your immune system begins trying to fight it off. It sends white blood cells to the area to destroy the bacteria.
See your doctor immediately if you notice a change in color or odor of the fluid oozing from your wound. Purulent drainage is yellow, green, brown, or white and has a strong odor. The earlier an infection is caught, the easier it can be treated.
