In the adult population, it was estimated that for every 1 mL of blood removed, Hb concentration and hematocrit dropped by 0.07 g/L and 0.019%, respectively.4 Because in pediatric patients blood volume is less than in adults (estimated blood volume 80 mL/kg) and most analyzers are designed for standard adult tubes requiring a blood volume of 5–7 mL,5 multiple blood samples can cause iatrogenic anemia. [...]in the case of intra-abdominal blood loss related to solid organ injury, the subtle decline in Hb caused by samples may contribute to additional imaging, testing, or blood transfusions. [...]tachycardia, hypothermia, decreased oxygen saturation, and low Hb values suggest that the patient might have significant blood loss. [...]contrary to patients under general anesthesia, the spontaneous movements of the probe site can alter the SpHb reading. [...]literature data about the role of SpHb monitoring in pediatric trauma patients are scarce and inconclusive.
