Yellow fluid from a wound is usually recommended to be wiped clean with alcohol or iodophor. If the exudate is small, the exudation time is short, or there is no antiseptic medicine, the yellow fluid can also not be wiped. Yellow fluid from wounds is often seen in falls or abrasions after the skin breaks down, followed by the phenomenon of yellow fluid, usually due to the exudation of tissue fluid, which needs to be wiped off with iodophor or saline. In addition, if the phenomenon of yellow fluid appears in the wound after surgery or debridement and suturing, it indicates that there is subcutaneous fluid and bacterial infection inside the wound, and it may be necessary to remove the surface sutures, clean the necrotic tissues inside the wound, fill the gauze and place drainage tubes. If the oozing of yellow fluid is short-lived and has stopped on its own, the yellow fluid may not be wiped, but disinfection of the wound is usually recommended. In addition, wound care is also more important, and the wound should be dry and hygienic. It is also important to replenish the body with the necessary nutrients to promote wound healing.
