Abstract

Background and aims: During infant CPR, rescuers are sometimes difficult to maintain correct finger position. Aims: To investigate the usefulness of a Finger-Marker(FM) for maintaining correct finger position during two-thumb infant chest compressions. Methods: A total of 10 emergency physicians were enrolled and received 15 minutes training for correct two thumb position in infant CPR. After random coupling of participants, coupled two participants were performed standard 2-rescuers infant CPR two times with about 2 minutes with intervals of about one month. The twice simulations were classified into standard CPR group (SCG), FM group (FMG). All the subjects had no previous CPR experience using FM. Figure eight shaped FM sticker was made (size 3.5*2cm). Proper FM sticker placement was defined that vertical center of FM was situated at the mid-sternum and the upper horizontal line was aligned with just distal to inter-nipple line. All CPR processes were performed by 2010 AHA guideline. Results: There were no significant differences in mean compression rate and depth between two interventions (107.6/min vs. 109.1/min, p=0.783, 38.3mm vs. 38.1mm, p=0.931). Hands-off times and the rate of fully recoiled compression are similar between two groups (p=0.832, p=0.562). All FM stickers are correctly attached at proper point within 5 seconds of approaching the model. There were significant differences in the rate of correct finger position between two groups. (99.1% ± 0.9% in FMG, 80.3% ± 11.4% in SCG, p < 0.001). Conclusions: The PM sticker was useful in maintaining correct finger position during the two-rescuer infant manikin CPR and the sticker might be helpful to prevent internal organ injury.
