Two new chest compression methods might challenge the standard in a simulated infant model.

ABSTRACT

Paediatric cardiorespiratory arrest is a rare event that requires a fast, quality intervention. High-quality chest compressions are an essential prognostic factor. The aim of this prospective, randomized and crossover study in infant manikin 2-min cardiorespiratory resuscitation scenario is to quantitatively compare the quality of the currently recommended method in infants (two-thumb-encircling hand techniques) with two new methods (the new two-thumb and the knocking-fingers techniques) using a 152 compression-to-ventilation ratio. Ten qualified health professionals were recruited. Variables analysed were mean rate and the ratio of compressions in the recommended rate range, mean depth and the ratio of compressions within the depth range recommendations, ratio of compressions with adequate chest release and ratio of compressions performed with the fingers in the correct position. Ratios of correct compressions for depth, rate, chest release and hand position were always above 70% regardless of the technique used. Reached mean depth and mean rate were similar to the 3 techniques. No statistically significant differences were found in any of the variables analysed.Conclusion: In an infant manikin, professionals are able to perform chest compressions with the new techniques with similar quality to that obtained with the standard method. What is Known • Quality chest compressions are an essential prognostic factor in paediatric cardiorespiratory arrest. • It has been reported poor results when studied cardiorespiratory resuscitation quality in infants applying the recommended methods. What is New • In a simulated scenario, quality of chest compressions performed with two new techniques (nTTT and KF) is similar to that obtained with the currently recommended method (TTHT).
