RESUMO
OBJECTIVES: This study aimed to evaluate the impact of adding video conferencing to dispatcher-assisted telephone cardiopulmonary resuscitation (CPR) on pediatric bystander CPR quality. METHODS: We conducted a prospective, randomized manikin study among volunteers with no CPR training and among bachelor nurses. Volunteers randomly received either video or audio assistance in a 6-minute pediatric cardiac arrest scenario. The main outcome measures were the results of the Cardiff Test to assess compression and ventilation performance. RESULTS: Of 255 candidates assessed for eligibility, 120 subjects were randomly assigned to 1 of the 4 following groups: untrained telephone-guided (U-T; n = 30) or video-guided (U-V; n = 30) groups and trained telephone-guided (T-T; n = 30) or video-guided (T-V; n = 30) groups. Cardiac arrest was appropriately identified in 86.7% of the U-T group and in 100% in the other groups (P = 0.0061). Hand positioning was adequate in 76.7% of T-T, 80% of T-V, and 60% of U-V, as compared with 23.4% of the U-T group (P = 0.0001). Fewer volunteers managed to deliver 2 rescue breaths/cycle (P = 0.0001) in the U-T (16.7%) compared with the U-V (43.3%), the T-T (56.7%), and the T-V groups (60%).Subjects in the video groups had a lower fraction of minute to ventilate as compared with the telephone groups (P = 0.0005). CONCLUSIONS: In dispatcher-instructed children CPR simulation, using video assistance improves cardiac arrest recognition and CPR quality with more appropriate chest compression technique and ventilation delivering. The long interruptions in chest compression combined with the mixed success rate to deliver proper ventilation raise question about ventilation quality and its effectiveness.
