About
The research protocol consists of taking aliquots of biological specimens from skin swabs, nasopharyngeal swabs, and fecal swabs. the samples will be taken at time 0 of admission to the Pediatric ICU, one week after admission, and two weeks after admission to compare the bacterial populations present at the different sampling sites.
Full description
Pediatric burns (0-14 years) make up 26% of emergency room admissions for burns, with 73% of cases in children under 5 years old. The most common burns are thermal from boiling liquids, followed by open flames and fireworks. Severe burns (>20% of body surface area) provoke a systemic inflammatory response that causes hypovolemia, tissue hypoperfusion, and metabolic stress, establishing a vicious cycle that is difficult to break.
Burn trauma can also compromise the intestinal barrier, composed of cellular junctions (tight junctions), damage to which increases intestinal permeability. This promotes the passage of luminal contents into the systemic circulation, aggravating the immune and inflammatory response. Gut dysfunction is often accompanied by dysbiosis of the microbiota, with risk of bacterial translocation to sterile organs (liver, lungs, brain), contributing to systemic complications in critically ill patients.
The study hypothesizes that burn trauma increases intestinal permeability, promoting bacterial translocation and anticipating infectious complications. Analyzing microbial populations at exposed sites (skin, gut, BAL) during trauma and pediatric ICU care may help to better understand the origin of septic complications.
