This type of drainage is a sign of healing, and it is not usually a cause for concern when it appears in normal amounts. Serosanguineous drainage that becomes redder may be an indication of active bleeding, a reopened wound, or a hemorrhage.
After the initial discharge of a bit of pus and blood, your wound should be clear. If the discharge continues through the wound healing process and begins to smell bad or have discoloration, it's probably a sign of infection.
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.
When you get a scrape or an abrasion, serous fluid (which contains serum) can be found at the healing site. Serous fluid, also known as serous exudate, is a yellow, transparent liquid that aids the healing process by providing a moist, nourishing environment for the skin to repair.
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.
Purulent Wound Drainage
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.
Healthy granulation tissue is pink in colour and is an indicator of healing. Unhealthy granulation is dark red in colour, often bleeds on contact, and may indicate the presence of wound infection. Such wounds should be cultured and treated in the light of microbiological results.
Serous drainage is mostly clear or slightly yellow thin plasma that is just a bit thicker than water. It can be seen in venous ulceration and also in partial-thickness wounds. Generally, this is not one of the types of wound drainage that leaves much color on a bandage.
Depending on the location and type of infection, pus can be many colors, including white, yellow, green, and brown. While it sometimes has a foul smell, it can also be odorless.
Should I drain pus out of an infected wound? No, you should not drain pus out of an infected wound yourself. Let a doctor or medical professional handle treatment. Follow their instructions for proper care.
But pus is a natural part of the healing process for wounds. 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.
Symptoms of an infected cut or wound can include: redness in the area of the wound, particularly if it spreads or forms a red streak. swelling or warmth in the affected area. pain or tenderness at or around the site of the wound.
Q: Is it better to bandage a cut or sore, or air it out? A: Airing out most wounds isn't beneficial because wounds need moisture to heal. Leaving a wound uncovered may dry out new surface cells, which can increase pain or slow the healing process.
The complicated mechanism of wound healing occurs in four phases: hemostasis, inflammation, proliferation, and remodeling.
If the wound environment is dry, the cells will have to find moisture deep in the wound bed so that they can migrate. This slows down the healing process. In fact, studies show that moist wounds heal 50 % faster than dry wounds.
Minor scrapes may be uncomfortable, but they usually heal within 3 to 7 days. The larger and deeper the scrape, the longer it will take to heal. A large, deep scrape may take up to 1 to 2 weeks or longer to heal. It's common to have small amounts of fluid drain or ooze from a scrape.
Should I use a bandage? Leaving a wound uncovered helps it stay dry and helps it heal. If the wound isn't in an area that will get dirty or be rubbed by clothing, you don't have to cover it.
Infection of the wound triggers the body's immune response, causing inflammation and tissue damage, as well as slowing the healing process. Many infections will be self-contained and resolve on their own, such as a scratch or infected hair follicle.
If the infection is minor such as infected hair follicle, scratch, or a small cut, it normally heals on its own with time. In severe conditions, the wound needs medical attention and should be treated immediately to avoid further damage to the body.
