[Changes in the international recommendations on neonatal resuscitation, 2010: comments].

Since previous publication in 2005, the most significant changes that have been addressed in the 2010 International Liaison Committee on Resuscitation (ILCOR) recommendations are as follows: (i) use of 2 vital characteristics (heart rate and breathing) to initially evaluate progression to the following step in resuscitation; (ii) oximetry monitoring for the evaluation of oxygenation (assessment of color is unreliable); (iii) for babies born at term it is better to start resuscitation with air rather than 100% oxygen; (iv) administration of supplementary oxygen should be regulated by blending oxygen and air; (v) controversy about endotraqueal suctioning of depressed infants born through meconium-stained amniotic fluid; (vi) chest compression-ventilation ratio should remain at 3/1 for neonates unless the arrest is known to be of cardiac etiology, in which case a higher ratio should be considered; (vii) use of therapeutic hypothermia for infants born at term or near term evolving to moderate or severe hypoxic-ischemic encephalopathy, with protocol and follow-up coordinated through a regional perinatal system (post-resuscitation management); (viii) cord clamping delay for at least 1 minute in babies who do not require resuscitation (there is insufficient evidence to recommend a time for clamping in those who require resuscitation) and, (ix) it is appropriate to consider discontinuing resuscitation if there has been no detectable heart rate for 10 minutes, although many factors contribute to the decision to continue beyond 10 minutes. Under certain circumstances, non-initiation of resuscitation could be proposed taking into consideration general recommendations, own results and parents' opinion.
