New guidelines for newborn resuscitation--a critical evaluation.

UNLABELLED: The 2010 International Liaison Committee on Resuscitation guidelines for newborn resuscitation represent important progress. The criteria for assessment are simplified based on heart rate and respiration only and there is no timing of stages after the first 60 sec. Instead of giving supplemental oxygen, the guidelines state that 'it is best to start with air'. However, the optimal oxygen concentration later in the process and for premature babies is not yet clear. A description of an adequate heart rate response is not given, and the cut-off of 100 bpm may be arbitrary. There are still no clear recommendations regarding ventilation, inspiratory time, use of positive end expiratory pressure or continuous positive airway pressure. The guidelines do not mention which paCO2 level might be optimal. As colour pink assessment and routine suctioning of airways are not recommended anymore, there is an urgent need to obtain international consensus and create a new and revised Apgar score without these two variables.

CONCLUSION

In spite of improved guidelines for newborn resuscitation, there is still a number of unanswered questions and a need for more delivery room studies.
