Colonic perforation following prolonged hypovolaemia in a major burns injury.
Perforation of the lower gastrointestinal tract is rare in burns patients. A 41-year-old male, who sustained 40% total body surface area burns and subsequently developed an acute abdomen on day 15 postburn, is presented. Emergency management included a subtotal colectomy and ileostomy formation performed to repair a perforated transverse colon found at laparotomy. The burns were debrided and grafted and the patient required cardiac, renal and respiratory support initially in the ITU setting before making a complete recovery. It is suggested that ischaemia caused the perforated transverse colon due to a prolonged low flow state. This was not detected until invasive cardiovascular catheterisation was performed and revealed a hypovolaemic state, which was corrected by fluids and noradrenaline. Both the previous cardiac history of the patient (Fallot's Tetralogy repair) and the noradrenaline may have exacerbated the low flow state within the mesenteric circulation leading to ultimate perforation. This case highlights the difficulties that may arise in resuscitating a patient who has previously had a cardiac defect repaired. Despite repair, abnormal physiology may persist resulting in misleading observations that produce undetected hypovolaemia with subsequent adverse events, as in this case. In such patients, early invasive cardiovascular monitoring should be considered.
