Adaptive Collaboration Between the Emergency Department and Neonatal Intensive Care to Treat a 16-Month-Old in Sepsis-Related Hemolytic Anemia with a Hemoglobin of 1.7 g/dL: A Case Report.

Background/Objectives: An 8-kg, 16-month-old child was brought to the emergency department of a regional community hospital with shallow respirations. Due to her pallor and the diluted appearance of the first blood sample, the emergency physician suspected sepsis associated with severe anemia. Her first laboratory results revealed a hemoglobin of 1.7 g/dL. Subsequent laboratory data revealed positive fibrin split products and hypofibrinogenemia with reticulocytosis. Because this regional community hospital did not have a pediatric intensivist, the emergency physician instead consulted a neonatal intensivist for guidance. Methods: A femoral intraosseous line was placed to allow aggressive massive transfusion. After consultation with the neonatal intensivist, packed red blood cells were transfused at a rate of 30 mL/kg/h. After transfusion, the patient became agitated and required repeated paralytic, sedative, and analgesic boluses of succinylcholine, ketamine, midazolam, dexmedetomidine, and fentanyl, with fentanyl and dexmedetomidine drips. The patient arrived at a tertiary care center 13 h after admission. Results: At the tertiary care center, the patient was weaned off the drips and was theorized to have secondary autoimmune hemolytic anemia due to sepsis after positive direct and indirect Coombs test. She was treated with a course of antibiotics, including cefepime and vancomycin, without steroids or immunotherapy. Five months later, her hemoglobin had returned to 12.1 g/dL, and she tested negative on direct and indirect Coombs test. Conclusions: This case highlights the importance of collaboration between and within departments to successfully manage pediatric hemostatic resuscitation.
