Emergency management of lower gastrointestinal bleed in children.
Lower gastro intestinal bleed (LGIB) is defined as any bleeding that occurs distal to the ligament of Treitz (situated at the duodeno jejunal junction). It constitutes the chief complaint of about 0.3 % of children presenting to the pediatric emergency department(ED). Among Indian children the most common causes are colitis and polyps. In most of the cases of LGIB the bleeding is small and self limiting, but conditions like Meckel's diverticulum often presents with life threatening bleeds. The approach in ED should include in order of priority-assessment and maintenance of hemodynamic stability, confirmation of LGIB and then to attempt for specific diagnoses and their management. This is achieved with help of rapid cardiopulmonary assessment, focused history and examination. The management of all serious hemodynamically significant bleeds includes, rapid IV access, volume replacement with normal saline 20 ml/kg, blood sampling (for cross matching, hematocrit, platelet, coagulogram and liver function tests), Inj. Vit K 5-10 mg IV, acid suppression with H2 antagonists/PPI and nasogastric lavage to rule out upper gastrointestinal bleed. Continuous ongoing monitoring of vital signs is important after stabilization. In ill looking infant, infectious colitis, Necrotizing enterocolitis (NEC), Hirschsprung enterocolitis and volvulus and in older infants and children, intussusceptions, typhoid fever, volvulus should be looked for. Proctosigmoidoscopy remains the first investigation to be done and reveals majority of etiology. Multidetector CT scan, Tc 99 m RBC scan, angiography and Push enteroscopy are the further investigation choices according to the clinical condition of the child. Intra operative enteroscopy is reserved for refractory cases with an obscure etiology.
