Effectiveness of innovative chest compression on the emergency department stretcher by an alternative method: a randomized controlled crossover trial.

Comparison of the three methods standing-on-a-stool (SS), one knee kneeling on a stretcher (KS), and kneeling at the same height as the patient's bed on the kneeling stool (KK) to evaluate the yielded of highest CPR quality and rescuer comfortability. A prospective randomized cross-over study which compares the three different rescuer positions for their effectiveness of chest compression. Conducted at a tertiary care between 19 and 22 Aug 2022. Emergency personnel aged 18 years or older, who completed the AHA-approved BLS course. The chest compression data was obtained by the ALIVE AED manikin® and AED reporting system. The information on the CPR quality and post-test questionnaires assessing the participants' preference, satisfaction and modified Borg's scale score was collected. The three methods shown no statistically significant difference in adequate chest compression depth (percentage). KK was not superior than SS at chest compression rate (P = 0.05). The adequate full chest recoil achieved with KK and KS were significantly higher than that of SS. However, there were no statistical difference between the three methods in the modified Borg's scale score. Based on the satisfying score, the rescuers preferred KK to either SS (p 0.007) or KS (p 0.012). The three methods shown no statistically significant difference in adequate chest compression depth (percentage). Still, both KK and KS provided more adequate chest recoil, so we would recommend using these two methods in the ED.Clinical trial registry: This study was retrospective registration in thaiclinicaltrials.org (TCTR20230119002, 19/1/2023).
