Symptoms of infection after scalding

summary

After burn, the skin, as a natural barrier against the invasion of microorganisms, is destroyed, resulting in bacterial infection. The common bacteria are Staphylococcus aureus, Pseudomonas aeruginosa, Citrobacter freundii, nitrate negative bacilli and other intestinal negative bacilli. Severe burns may also cause toxic bacteria, anaerobic bacteria and virus infection. The symptom of infection after scald? Let's talk about it

Symptoms of infection after scalding

Different bacterial infection can produce different changes. Staphylococcus aureus infection is light yellow sticky secretion; Hemolytic streptococcus infection was light brown thin secretion; Pseudomonas aeruginosa infection was green or blue-green sticky secretion with sweet smell; Anaerobic bacteria infection can smell fecal odor.

There are dark gray or black necrotic spots on the wound surface, such as those infected by gram-negative bacilli. Bacterial invasion of deep blood vessels leads to ischemic necrosis, wound deepening and delayed wound healing.

The gray spots on the eschar or eschar wound mostly indicate fungal infection. The spots developed rapidly to the wound surface and fused into flaky villi. The surface color gradually became obvious, showing gray white, light green, light yellow or brown, and a thin layer of powder appeared on the wound after a few days.

matters needing attention

Reasonable nutritional support and metabolic conditioning is an important link in the prevention and treatment of patients with invasive infection. After burn, due to the exudation of wound, loss of a large amount of protein, ultra-high metabolism, increased consumption, wound repair needs a lot of protein and energy supply. Therefore, burn patients need to eat high protein, high calorie nutrients to maintain nitrogen balance.
