[Neonatal-emergencies: basics in cardiopulmonary resuscitation]

Abstract

The international guidelines for neonatal resuscitation were recently updated by the American Academy of Pediatrics (AAP), the American Heart Association (AHA) and the International Liaison Committee on Resuscitation (ILCOR). The most important steps in resuscitation of the newly born infant are oxygenation and ventilation, including endotracheal intubation. These fundamental techniques will be emphasized and discussed in a problem-oriented approach. The clinical assessment of the newly born infant is based on a triad of respiration, heart rate and color. If indicated, resuscitation has to be initiated approximately 30 s after birth, i. e. prior to determination of the 1 min. Apgar score and umbilical artery pH. The key to successful neonatal resuscitation is establishment of adequate ventilation; it should commence - after oropharyngeal suctioning and ineffective tactile stimulation - when the heart rate drops < 100 bpm. Clinical evidence supporting the hypothesis that ventilation with room air versus 50 or 100 % oxygen is preferable in terms of neurological outcome is still preliminary and requires further investigation. Chest compressions should be administered if the heart rate remains < 60 bpm (or heart rate 60 to 80 bpm and not rising) despite adequate assisted ventilation. There should be a 3 : 1 ratio of compressions to ventilations to achieve approximately 120 events per minute. Moreover, the international guidelines recommend crystalloid volume expanders (normal saline or Ringer's lactate), red blood cells, sodium bicarbonate and naloxone for cardiopulmonary resuscitation of the newly born infant.
