This document discusses exchange transfusions in infants. It describes double volume exchange transfusions, which replace an infant's total blood volume twice, and partial exchange transfusions, which either increase or decrease an infant's hematocrit. It provides details on how to calculate exchange volumes and outlines the procedures, potential complications, necessary materials, pre- and post-procedure labs, and follow-up care for both double volume and partial exchange transfusions. The goal of exchange transfusions is to treat conditions like hyperbilirubinemia, hyperammonemia, or severe anemia in infants.
