Abstract P41: New Effective Technique of Chest Compression for Infants
[Introduction] Current AHA guidelines suggest a two thumb (encircling) method for two rescuers and a two finger technique for single rescuers. It is known that the former is better than the latter, because the two finger technique is prone to fatigue. A better technique for infant resuscitation by a single rescuer is needed.
[Hypothesis] Our new technique using a thumb and an index finger (figure⇓) is better than the currently suggested two finger technique.
[Methods] We made an infant manikin that can evaluate chest compression quality including compression depth. Trained CPR providers performed chest compressions targeting 1/3 of chest diameter for five minutes continuously using the two thumb method, the two finger technique, and our new technique (n=20 each). The results of chest compression quality including depth were tracked and compared for each compression method.
[Results] With the two finger technique the depth of chest compression was initially shallow and decayed significantly in five minutes. However, our new technique retained the quality of chest compression and was equally effective as the two thumb method (table⇓).
[Conclusions] Our new technique of chest compression in infants is better than the current two finger technique and equally effective compared with the two thumb method. This new method should be considered in single rescuer situations.
