Evaluation of respiratory function monitoring at the resuscitation of prematurely born infants

Our aim was to determine whether neonatal trainees found respiratory function monitoring (RFM) helpful during the resuscitation of prematurely born infants, what decisions they made on the basis of RFM and whether those decisions were evidence based. Fifty one trainees completed an electronic questionnaire. Eighty-three percent found the tidal volume display useful, 59 % altered the inflation pressure based on the tidal volume: 52 % considered 5 ml/kg adequate; 33 % 4 ml/kg; 13 % 6 ml/kg; and 2 % 7 ml/kg, despite no evidence on which to decide was the optimum tidal volume. If there was no detectable expired carbon dioxide (CO₂), 30 trainees said they would reintubate, yet the absence of expired CO₂ can indicate inadequate vasodilation of the pulmonary circulation rather than inappropriate placement of the endotracheal tube. If there was no chest wall expansion, but expired CO₂, a third of junior trainees would reintubate which is inappropriate. If the oxygen saturation (SaO2) was 2 > 85 % by 1 min. Conclusions: The usefulness of respiratory function monitoring for trainees during neonatal resuscitation is often not evidence based.
