What symptom does infection have after scald?

summary

When we are scalded, we should take care of the wound carefully, because if we don't pay attention, the wound will be infected. The harm caused by scald infection is great, such as sepsis and bacteremia, and the possibility of renal failure. The treatment of complications caused by it is very difficult, so it is very important to clean the scalded part. What symptom does infection have after scald? Let's talk about it

What symptom does infection have after scald?

Sepsis: cells (or other microorganisms) invade the blood stream and propagate in the blood or organs and tissues. At the same time, they produce a large number of mycins and products, causing systemic clinical symptoms, accompanied by changes in hemodynamics and metabolism-- It's called sepsis. If septic shock occurs, the prognosis is poor. The diagnosis of sepsis is usually based on positive blood culture. The bacteria causing sepsis may come from burn wound, venous catheter infection, visceral infection, or enterogenous infection. Sepsis is the late manifestation of wound toxicosis.

Bacteremia: the transient appearance of living bacteria in the blood circulation is called bacteremia. It often occurs in the process of escharectomy or decrustation of scald wound, with mild clinical symptoms and no changes in hemodynamics and blood biochemistry.

Burn wound sepsis: Pseudomonas aeruginosa propagates in the normal tissue around the burn wound, invades lymphatic vessels and vascular walls or penetrates into blood vessels to form embolism. The release of a large number of endomycin into the blood circulation, the clinical symptoms of sepsis, blood culture is often negative, known as burn wound sepsis. There was perivasculitis or vasculitis in the tissue biopsy around the wound. The amount of bacteria in the tissue around the wound is generally greater than 105 / g tissue. However, this index is not an index for the diagnosis of wound sepsis. It should be judged by biopsy and systemic symptoms.

matters needing attention

Special parts such as the head, face and neck burns, the injured area is not necessarily large, but the facial tissue itself is relatively loose, rich in blood supply, burns often cause severe swelling of the face and neck, compression airway, compression to a certain extent, people will suffocate. Therefore, these parts of the scald, regardless of size, should be sent to the hospital immediately.
