Abstract 113: Schoolchildren Can Provide Effective Basic Cardiopulmonary Resuscitation Plus Automated External Defibrillation as Adults: A Prospective Intervention Study.
Background: public access to defibrillation improves survival in out of hospital sudden cardiac death victims. Children can learn and retain skills quickly. Training cardiopulmonary resuscitation (CPR) skills for schoolchildren would be one of the most effective ways of achieving this goal.
Objectives: to determine if schoolchildren can learn and perform basic CPR using an automated external defibrillator (AED) as well as adults.
Methods: a prospective study was conducted in three state schools. We include 172 participants divided in four age (years) groups: ages 11–12 (n=41), 13–14 (n=41), 15–17 (n=44) and age 18 or more (n=46) corresponding adults group. Interventions: all participants received a CPR-AED manual to be read at home. On the training day subjects were taught CPR-AED theory and skills in one lesson (practice-while-watching format) lasting 90 minutes by an AHA instructor. Main outcome measure: after training, a 100 points questionnaire was used to access acquisition of CPR knowledge. Practical skills were accessed evaluating effectiveness to perform the first 3 links of the survival chain. All performance was recorded by a PC Skill Reporter Software.
Results: statistical analyses were performed using T test, Mann-Whitney U, Kruskal-Wallis. Age group 11–12 had significantly less weight than other groups (p<0,05). Correct hand position and compression depth (mm) in group age 11–12 differs significantly from adults group (p<0,05 and p<0,001, respectively). Multivariate analyses confirm independently relation between age, weight and chest compression depth. Others skills evaluated were: time to begin chest compression after EMS activation, compression rate, average volume during ventilation, hands off while operating AED , operate AED correctly and cognitive evaluation after training. They were at least similar in schoolchildren's groups comparing to adults.
Conclusions: In this study, schoolchildren in group age 11–12, perform chest compression with some difficulty. Ability to achieve an adequate depth of chest compression depended on children's age and weight. On the other hand, all other basic CPR skills, including AED operation and cognitive abilities can be learned and performed by children over age 11 at least as well as adults.
