BACKGROUND: Exchange transfusion and phototherapy have traditionally been used to treat jaundice and avoid the associated neurological complications. Because of the risks and burdens of exchange transfusion, intravenous immunoglobulin (IVIg) has been suggested as an alternative therapy for alloimmune hemolytic disease of the newborn (HDN) to reduce the need for exchange transfusion. OBJECTIVES: To assess the effect and complications of IVIg in newborn infants with alloimmune HDN on the need for and number of exchange transfusions...

The current evidence regarding the indication, advantages and risks of red blood cell transfusion (RBCT) for preterm infants is discussed. This is an important area in Neonatology to be examined given that 90% of extremely low birth weight infants receive RBCT and many controversies remain regarding when to transfuse and the risks of RBCT. The various treatment thresholds and guidelines used are presented and we compare the short-term clinical benefits of liberal and restrictive RBCT in preterm infants; the majority of these are equivocal and sadly long-term outcome data is limited...

Umbilical cord blood (UCB), rich in stem/progenitor cells, is partially eliminated from the bloodstream during childbirth because the cord is immediately clamped. We hypothesize that transfusion of autologous UCB to premature infants after delivery could serve as an adjuvant modality for preventing the development of prematurity-related complications. We randomly enrolled 20 preterm infants born before 32 weeks of gestational age (GA), all of whom developed anemia, necessitating transfusion of red blood cells (RBCs)...

Postnatal adaptation in preterm newborn comprises complex physiological processes that involve significant changes in the circulatory and respiratory system. Increasing hemoglobin level and blood volume following placental transfusion may be of importance in enhancing arterial oxygen content, increasing cardiac output, and improving oxygen delivery. The European consensus on resuscitation of preterm infants recommends delayed cord clamping (DCC) for at least 60 s to promote placenta-fetal transfusion in uncompromised neonates...

Kidneys are physiologically hypoxic due to huge oxygen consumption for tubular reabsorption. The physiological hypoxia makes the kidney an appropriate organ for sensitively detecting oxygen levels and producing erythropoietin (EPO). In preterm neonates, immature kidneys cannot produce sufficient EPO, which results in anemia of prematurity (AOP). The cause of EPO insufficiency in AOP has been unclear, therefore current therapeutic options are transfusion and injection of recombinant human EPO. This report shows that the cause of insufficient EPO production in AOP is elevated renal oxygen levels due to poor oxygen consumption by immature tubules...

BACKGROUND: Placental transfusion (by means of delayed cord clamping (DCC), cord milking, or cord stripping) confers benefits for preterm infants. It is not known if providing respiratory support to preterm infants before cord clamping improves outcomes. OBJECTIVES: To assess the efficacy and safety of respiratory support provided during DCC compared with no respiratory support during placental transfusion (in the form of DCC, milking, or stripping) in preterm infants immediately after delivery...

BACKGROUND: Hyperbilirubinemia occurs in over 80% of newborns and severe bilirubin toxicity can lead to neurological dysfunction and death, especially in preterm infants. Currently, the risk of bilirubin toxicity is assessed by measuring the levels of total serum bilirubin (TSB), which are used to direct treatments including immunoglobulin administration, phototherapy, and exchange transfusion. However, free, unbound bilirubin levels (Bf) predict the risk of bilirubin neurotoxicity more accurately than TSB...

BACKGROUND: The objective of this study was to determine if a change in cryoprecipitate transfusion policy impacts donor exposure and fibrinogen level in a neonatal intensive care unit (NICU) population. STUDY DESIGN AND METHODS: The cryoprecipitate policy was changed from transfusing 10ml/kg to a maximum of 1 unit per transfusion in January 2013. Data were obtained via retrospective chart review of all infants receiving cryoprecipitate transfusions from January 2008 to February 2015 in the NICU at Christiana Hospital...

In the decades since the introduction of ultrasound into routine obstetric practice, the advantages of ultrasound have moved beyond the simple ability to identify multiple pregnancies antenatally to the possibility of screening them for fetal anomalies, pre-eclampsia, preterm birth, and the complications specific to monochorionic pregnancies. Screening studies have often excluded twins because physiological differences impact on the validity and sensitivity of the screening tests in routine use in singletons, and therefore, the evidence of screening performance in multiple pregnancy lags behind the evidence from singleton pregnancies...

The aim of this study was to review fetoscopic laser photocoagulation (FLP), which ablates placental vascular anastomoses to treat twin-twin transfusion syndrome (TTTS). A review of studies reporting on the procedures, outcomes, complications and nonconventional applications of FLP for TTTS was conducted. FLP has been established as the primary treatment for monochorionic twin pregnancy associated with TTTS at 16-26 weeks. FLP is the only therapy that directly addresses the underlying pathophysiology. The recent technique modification of FLP, referred to as the 'Solomon technique', induces selective coagulation to connect the anastomoses ablation sites and has been introduced to reduce residual anastomoses...

Haemophagocytic lymphohistiocytosis (HLH) is a rare disease with a sepsis-like progression that leads to multiple organ dysfunction syndrome, especially in preterm infants. We present herein a case of HLH in a premature infant presenting with disseminated intravascular coagulopathy (DIC) and liver failure. A male infant, with weight 810g and delivered at the gestational age of 25 weeks and 2 days, was misdiagnosed with tyrosinaemia for several weeks. He presented with anaemia, thrombocytopaenia, persistent DIC, and elevated liver enzymes despite continuous transfusion and broad-spectrum antibiotics...
