Problems in the measurement of functional residual capacity.

Accurate assessment of lung volume in infancy is important to determine the impact of disease and the efficacy of therapies. A new generation of infant plethysmographs with lower apparatus deadspace has been produced, but gives lower volume results than those from older traditional plethysmographs. We hypothesized that the new plethysmographs might have greater sensitivity to the adiabatic effect and hence they, rather than the traditional plethysmographs, produced erroneous results.

The mortality index for neonatal transportation score: a new mortality prediction model for retrieved neonates.

Objective: To develop a mortality prediction score for retrieved neonates based on the information given at the first telephone contact with a retrieval service.

Methods: Data from the New South Wales Newborn and Pediatric Emergency Transport Service database were examined. Analysis was performed with the results for 2504 infants (median gestational age: 36 weeks; range: 24-43 weeks) who were <72 hours of age at the time of referral and whose outcome (neonatal death or survival) was known.

An illness severity score and neonatal mortality in retrieved neonates.

Unlabelled: The Clinical Risk Index for Babies (CRIB) score is a simple tool to measure clinical risk and illness severity in very low birth weight infants. The aim of this study was to determine if a modified CRIB score (MCRIB) used at first telephone contact with a transport service differentiated between retrieved infants who did or did not die in the neonatal period and hence might be a useful triage tool. A retrospective cohort study of 2504 infants, median gestational age 36 weeks and birth weight 2782 g, transported by the New South Wales Newborn and Paediatric Emergency Transport Service (NETS) was performed.
