Introduction
How to manage a purulent wound:
If the amount of pus draining from the wound is minimal and there are no obvious signs of acute inflammation—such as marked erythema, swelling, pain, or increased local skin temperature—around the wound, conservative management may suffice.
However, if the wound exhibits a fluid-like fluctuance upon palpation, accompanied by prominent signs of acute inflammation—including erythema, swelling, warmth, and pain—and fresh purulent discharge, this typically indicates an extensive underlying suppurative infection.
Wound suppuration refers to inflammatory exudation resulting from wound infection. The management approach varies depending on the severity of suppuration and should be tailored according to the clinical condition.
If only a small amount of pus is present and there are no obvious signs of acute inflammation—such as marked erythema, swelling, pain, or elevated skin temperature—around the wound, this suggests a mild localized infection. In such cases, gently clean the purulent tissue with a cotton swab, then repeatedly disinfect the wound and surrounding skin with povidone-iodine or hydrogen peroxide. Finally, cover the wound with sterile gauze or an adhesive bandage.
If the wound exhibits a fluid-like fluctuant sensation, accompanied by prominent signs of acute inflammation—including erythema, swelling, warmth, and pain—and fresh pus is draining, this typically indicates a more extensive suppurative infection beneath the wound surface. Prompt medical attention is required: the wound must be surgically incised at a hospital to debride necrotic tissue and drain the abscess cavity, followed by repeated alternating irrigation with hydrogen peroxide and povidone-iodine, and subsequent wound closure.
