This document provides guidelines for red blood cell (RBC), fresh frozen plasma (FFP), platelet, intravenous immunoglobulin (IVIG), and albumin transfusions in infants. For RBC transfusions, the guidelines specify hemoglobin level thresholds for transfusion based on factors like oxygen needs, respiratory support, and medical conditions. The document also presents a case study example. Guidelines for FFP, platelet, IVIG and albumin transfusions provide indications based on coagulation abnormalities, bleeding risks, and bilirubin/albumin levels.
