Dominant vs. Non-Dominant Hand in Pediatric Cardiopulmonary Resuscitation: A Randomized Crossover Simulation Trial

Abstract

Aim: This study assessed the impact of hand dominance on the quality of pediatric chest compressions during simulated cardiopulmonary resuscitation (CPR). Materials and Methods: A randomized crossover trial was conducted with 31 medical students trained in pediatric life support. Each participant performed chest compressions using both the dominant (DCC) and non-dominant hands (NDCC) on a high-fidelity pediatric simulator. Key CPR metrics, including compression depth, rate, hand placement accuracy, and rescuer fatigue, were analyzed. Results: No statistically significant differences were found between DCC and NDCC in terms of compression depth (p>0.05), compression rate (p>0.05), rescuer fatigue (p=0.864), or perceived ease of compression (p=0.612). However, hand placement accuracy was significantly better with NDCC (p=0.029). Additionally, anthropometric factors, particularly body mass index (BMI) and height, positively correlated with compression depth and frequency, suggesting that individuals with higher BMI and height may achieve more effective compressions. Conclusion: Hand dominance does not affect CPR quality, except for improved correct hand placement with NDCC. Personalized CPR training should consider rescuer characteristics to optimize performance. Further research is needed to refine pediatric resuscitation strategies.
