Iatrogenic phlebotomy loss resulting from the intensive clinical monitoring in the weeks immediately following birth remains the primary cause of neonatal anemia and the need for red-blood-cell (RBC) transfusion. Reducing RBC transfusion needs in the neonatal intensive care unit (NICU) requires new approaches for...

Investment in medical research is expected to have a payback; we assume that with the passage of time increased knowledge and understanding of disease process will inevitably lead to improved treatment and better outcome. This optimistic paradigm has proved valid for some of the major killer diseases, including heart...

Blood gases are measured from an arterial blood sample to evaluate the respiratory adequacy and oxygen status of the critically ill patient. For the adult patient, the arterial blood is sampled either by arterial puncture or from an indwelling catheter. In neonates and children, the wish to minimize iatrogenic blood...

Capillary blood sampling via a heel lance is the most common procedure performed in hospitalized neonates. Adequate training and supervision of the personnel performing the procedure is necessary to prevent/minimize inadequate sampling volumes, false laboratory results and complications such as pain. Efforts should be ...

Supported by Pennsylvania Hospital Kernicterus Fund and the Eglin Fund In the late 1980s, the question whether bilirubin damaged the brain of healthy infants was unanswered. The absence of documented evidence influenced the formulation of the 1994 consensus-based guidelines...

The University College London Hospitals (UCLH) is one of the largest NHS trusts in England. The Elizabeth Garrett Anderson and Obstetric Hospital houses the Trust's gynecology, obstetric and neonatal services. At the neonatal unit, blood gas monitoring has historically been done by a combination of blood gas...

Preterm, very-low-birth-weight babies require intensive laboratory testing, including frequent blood gas analysis, during the first few weeks of life. It has been estimated that the weekly blood loss associated with phlebotomy for blood testing can amount to as much as 30 % of the total blood volume of these tiny,...

A raised serum bilirubin (hyperbilirubinemia) and consequent jaundice is a common feature during the neonatal period; more than half of all newborns develop mild jaundice – with serum bilirubin rarely exceeding 150 µmol/L – during the first week or two of life. This transitory phenomenon usually resolves spontaneously ...

About half of all newborn infants born at term develop jaundice during their first days of life, and the lower the gestational age the more frequent the jaundice is. Newborns develop hyperbilirubinemia because of a large bilirubin production, low hepatic excretion and enterohepatic recirculation. At birth the newborn ...

Arterial blood gas analysis with the measurement of the partial pressure of carbon dioxide in arterial blood may be performed in the Pediatric ICU to evaluate the efficacy of ventilation or evaluate acid-base status. Although the direct measurement of PaCO₂ remains the gold standard, it provides only a single...
