No improvement in neonatal death rate
Despite significant developments in neonatal medicine over the past decade or two there has been no overall reduction in the number of neonatal deaths according to the results of a recently published US study.
Researchers at the University of Colorado in Denver performed a retrospective study of all 779,385 live...

Capillary blood gases - to arterialize or not
The ‘gold standard’ sample for blood gas analysis is arterial blood obtained via an indwelling arterial catheter or by arterial puncture. For a number of reasons capillary blood is an attractive substitute sample that is routinely used in some clinical settings.
The purpose of this article is to examine the evidence ...

Treatment of neonatal jaundice
Transient increase in serum bilirubin concentration is a normal physiological feature of the neonatal period and this rise is sufficient to cause visible jaundice in around 60 % of newborns. For most the condition is harmless and resolves spontaneously with no long-term effects.
However for those neonates with...

Cord blood gas analysis - a review
Umbilical cord blood gas analysis has for many years been recommended for assessment of newborn babies after high-risk delivery associated with possible hypoxic stress and consequent risk of permanent brain damage. More recently there has been an increasing trend towards its routine use after all deliveries.

Severe hyperbilirubinemia in the UK
Increased serum bilirubin (hyperbilirubinemia) and consequent jaundice are common during the neonatal period. Around 50 % of newborns develop some degree of jaundice, during the first week of life, but for the vast majority this is mild (serum bilirubin peaking no higher than 150-200 µmol/L) and spontaneously resolves ...

Fetal-to-neonatal transition: Part 2
Part 2: Red flags
The transition from fetus to newborn is a process of rapid physiological adaptation that is sometimes delayed by complications. Most newborns complete the process of transition with little or no delay.
These infants may demonstrate normal transitional findings, including tachypnea and tachycardia, ...

Fetal-to-neonatal transition: What is normal and what is not? Part 1
Part 1: The physiology of transition
The transition from fetus to neonate is a critical time
of physiological adaptation. While the majority of term infants
complete this process in a smooth and organized fashion, some
infants experience a delay in transition or exhibit symptoms of
underlying disease.
Careful...

Validation of hemoglobin estimation using blood gas analyzer
Modern blood gas analyzers often have incorporated technology
that allows hemoglobin measurement on the same blood sample used to
measure pH, pCO2 and pO2.
Clinicians working in a UK neonatal intensive care department where
such an instrument was routinely used for blood gases were keen to
exploit the newly available...

Cord blood sampling for lactate must not be delayed
Blood gas analysis of umbilical cord blood provides the means
for establishing the acid-base status of babies at the time of
birth. If there is to be any delay in sampling, the portion of cord
from which the sample is to be taken should be double-clamped and
thereby isolated from the placenta.
Previous studies have...
