Abstract 12921: One Hand Open Palm Technique for Infant Cardiopulmonary Resuscitation: A Randomized Crossover Study

Abstract

Introduction: The American Heart Association (AHA) CPR guidelines states that effective chest compression depth, rate and recoil are essential factors for establishment of return of spontaneous circulation. A recent survey from an international pediatric resuscitation collaborative showed that healthcare providers failed to meet the metrics of the AHA guidelines, with the greatest difficulty in achieving targeted chest compression depth in infants. The recommended techniques for infant compression include two finger (TFT) or two-thumb technique (TTT). We hypothesized using the heel of one palm (open palm technique, OPT) in infants will result in improved chest compression depth with decreased provider fatigue. Methods: Each participant performed three techniques including TFT, TTT, and novel open-palm technique (OPT) with randomization for sequence of techniques for each participant. Each technique was performed for 2 minutes followed by a 5-minute rest period on an infant manikin. Data were collected through Zoll R series defibrillators on chest compression depth, rate, and fraction. At the end of the study, each participant filled out a survey for difficulty level, finger fatigue, and rescuer fatigue. Results: Thirty pediatric critical care providers participated in the study consisting of 16 nurses, 9 respiratory therapists, 3 fellows, 2 nurse practitioners. The mean chest compression depth for OPT was significantly deeper (2.61 ± 0.63 cm) in comparison to TFT (2.25 ± 0.54 cm, p= 0.0004) but not significantly deeper in comparison to TTT (2.43 ± 0.46 cm, p= 0.0820). There were no significant differences between the three techniques in chest compression rate or chest compression fraction. The finger fatigue and rescuer fatigue surveys were graded from 0-10 with 10 being the most fatigue. OPT showed significantly less finger and rescuer fatigue in comparison to TTT and TFT (p<0.05). Conclusion: This study demonstrated that OPT generated improved chest compression depth with considerably less rescuer and finger fatigue. However, chest compression depth with all three techniques failed to meet the AHA infant goal of 4 cm. Further research is needed to optimize CPR performance to achieve the targeted chest compression depth in infants.
