Abstract 214: Which American Heart Association Guidelines---2005 or 2010---Are Associated with Better Skills Retention?
Background: The major difference between 2005 and 2010 statements for CPR is simplification of the ABCD primary sequence (CAB instead of ABC). Little is known about which one is associated with better skills retention.
Objective: To determine which guidelines is associated with better skills retention we conducted a randomized controlled trial comparing guideline 2005 and 2010.
Methods: We selected paramedics to participate voluntarily in the study and divided them into two groups: Group A received CPR training based in 2005 AHA guidelines, and group B received CPR training based in 2010 AHA guidelines. All training sessions occurred in the same way using manikins (Brad - Laerdal Company ®) after demonstration of the CPR sequence (CAB or ABC). Just after and after 30 days they were evaluated using Resuscianne Skillmeter®. At the same time they were recorded for posterior scoring by experienced BLS instructors using BLS/ACLS check list. Correct ventilations, tidal volume, minute ventilations, compression depth, compressions per minute, compression rate, wrong hand position compressions, too shallow compressions and incomplete released compressions were compared. Continuous variables were analyzed by the t-student test, and when necessary, the non-parametric Kruskall-Wallis test and the chi square for comparison between proportions.
Results: Group A (41 paramedics) and B (23 paramedics) were similar (age, gender, body mass index, past trainings and antidepressant or sedative drugs use). Tidal volume and minute ventilation were not different in both groups (p>0.05) but, number of correct ventilation were better in group A after 30 days (p=0.002). Compression depth was better in group B immediately and 30 days after (p=0.022 and p=0.04 respectively). Compression rate, wrong hand position compressions, too shallow compressions and incomplete released compressions was similar in both groups (p>0.05). Practical video scored evaluation were similar in both groups (p>0.05).
Conclusions: In 30 days providers trained with 2010 AHA guidelines was associated with better CPR quality based in the maintenance of good compression depth.
