Wound exudate, the fluid produced by wounds, plays a crucial role in healing. But there is more than one type, so here is what you need to know.
Types of exudate:
1. Serous: Clear and watery, this exudate is usually seen in the early stages of healing and indicates a healthy recovery. It can be a little sticky.
2. Sanguineous: Red and thin, containing blood, it may appear in fresh wounds. It's typically not a concern unless bleeding persists or increases.
3. Serosanguineous: Pink and thin, a mix of serous and sanguineous fluids, common in surgical incisions.
4. Purulent: What we know as pus. This is thick, yellow or green, and usually smells bad. This type of discharge indicates infection. Please consult with a doctor if you are treating a wound that starts to ooze this sort of exudate.
When should you worry about your wound?
๐ฉธ A sudden increase in the amount of fluid can indicate infection or other complications.
๐ฉธ Yellow, green, or foul-smelling exudate suggests infection.
๐ฉธ Fever, increased pain, or swelling around the wound requires medical evaluation.
Recognising changes in wound exudate can be key to ensuring proper healing and addressing complications early. Our Trifectiv wound dressing protocol, using woven gauze, allows you to quickly see if there are changes in the wound discharge when you change the dressing.
Always consult a healthcare professional if you're unsure or you are worried about infection.
