Differential Diagnosis for Pediatric Lower GI Bleed

In this episode of "PICU Doc On Call," Drs. Pradip Kamat and Rahul Damania discuss the acute management of a 14-year-old boy with severe rectal bleeding and hypertension, ultimately diagnosed with inflammatory bowel disease (IBD). They review the approach to pediatric lower GI bleeding, diagnostic workup, and imaging, emphasizing early recognition and resuscitation. They outline IBD management, including steroids, biologics such as infliximab, and nutritional support, while highlighting the importance of screening for infections before immunosuppression. The episode provides practical insights for PICU physicians on handling acute GI emergencies in children.
