Clinical Presentation & Protocol
Patient Usually Complains Of
Patient presents with acute onset of severe, non-bloody diarrhea progressing to bloody stools (hematochezia), accompanied by intense abdominal cramping. Denies recent travel outside endemic areas. No reported fever. Assessment for Shiga toxin-producing E. coli (STEC) O104:H4 initiated due to clinical presentation and epidemiological context.
Clinical Examination Findings
Patient appears dehydrated with dry mucous membranes and decreased skin turgor. Abdomen is soft but tender to palpation, primarily in the periumbilical and lower quadrants. Bowel sounds are hyperactive. No signs of peritoneal irritation. Neurological status intact; no evidence of hemolytic uremic syndrome (HUS) complications (e.g., pallor, petechiae, or altered mental status).
Treatment Protocol
Supportive care is the cornerstone of management. Maintain aggressive fluid resuscitation (IV isotonic crystalloids) to ensure adequate renal perfusion. Avoid antibiotics and antimotility agents, as these may increase the risk of HUS. Monitor renal function (BUN/Creatinine), CBC for hemolytic anemia/thrombocytopenia, and electrolyte balance closely.
