Wound bleeding, blood in the secretion is very sticky may be wound infection caused by pus, may also be fat liquefaction necrotic fat outflow, there may be secreted tissue fluid, need to be specific reasons for specific analysis. 1. Wound infection: due to untimely treatment of wounds or incomplete disinfection, there may be bacterial residues in the wounds, resulting in wound infection, especially purulent infection caused by Staphylococcus aureus, etc., which may be manifested as delayed healing of wounds and increased secretion, accompanied by redness, swelling, pain, odor and other manifestations of the wound site. 2. Fat liquefaction: when the wound is sutured too tightly or for other reasons, it will lead to local fat ischemia and thus cause necrosis and outflow, affecting wound healing. 3. may also be secreted tissue fluid: usually more common epidermal abrasion wounds, abrasions after the loss of stratum corneum to protect the wound, due to tissue fluid exuded from the wound surface, if not removed in a timely manner, it is very easy to pool in the wound on top of the gradual evaporation of water after the formation of a layer of white film-like things. Wounds bleeding blood in the secretion is very sticky situation should be timely to the hospital, under the guidance of the doctor symptomatic treatment.
