[Measurement of respiratory resistance in newborn infants with the oscillation method].

Total respiratory resistance (Ros) was measured in 36 healthy newborn infants, using a forced oscillation technique. In contrast to other oscillation methods, an existing phase shift between oscillation pressure and flow has been taken into consideration using a phase diagram. Concurrent measurements of airway resistance (Raw) were made using the body-plethysmographic method and pulmonary resistance (R1) by oesophageal balloon method. A significant relationship was found to exist between Ros and Raw (r=0.63), and also between Ros and R1 (R=0.64). The technique described proved to be practical in the newborns.

Transport of the newborn.

Analysis of facilities used in the transfer of neonates with respiratory distress syndrome (RDS) to the Newborn Intensive Care Unit (N.I.C.U.) of the Free University Amsterdam during the period 1969-1976 revealed many deficiencies. Most of the sick newborn infants were accompanied by inadequately trained personnel. In a number of cases they were in incubators which could hardly guarantee the neutral thermal temperature for the infant concerned. In the most cases there were no facilities either for resuscitation or for ventilatory assistance during transport. It was found that infants born in the referring hospitals more often required artificial ventilation than infants born in the University Hospital. Since the former were--on an average--more severely ill than the latter, the duration of ventilatory assistance was usually longer and their survival rate was lower. Retrospectively, in many instances referred infants were on admission already in such a condition that artificial ventilation should have been started long before. General aspects of newborn transport, viz. way of transport, incubator with facilities for emergency care i.e. artificial ventilation and intravascular therapy, accompanying personnel, stabilization of the infant, role of education and evaluation of the transport are discussed.

A ceiling module for a newborn intensive care unit.

In a traditional intensive care unit handling of neonates in incubators is usually obstructed by a surrounding clutter of electrical cables and gas tubings used for monitoring care. To solve these problems, an overhead module, provided with electrical and gas supplies and storage facilities for monitoring equipment and apparatus, was developed. The unit is suspended from the ceiling by two columns which serve as conduits for the gas tubing system and electrical wiring separately. The unit described allows for a maximum of flexibility and convenience for care.
