[Effect of a stabilization device for maintaining the balance of a CPR performer during ambulance transportation on quality of CPR in out-of-hospital cardiac arrest: a prospective randomized controlled trial].

OBJECTIVE: To investigate the effect of a stabilization device for maintaining the balance of a cardiopulmonary resuscitation (CPR) performer during ambulance transportation on quality of CPR in out-of-hospital cardiac arrest (OHCA). METHODS: A prospective randomized controlled trial was performed. 167 OHCA patients with cardiac arrest (CA) time < 10 minutes admitted to Cangzhou Central Hospital from October 2014 to January 2017 were enrolled, and divided into armed stabilization device group (n = 86) and unarmed stabilization device group (n = 81) by random number table. Restoration of spontaneous circulation (ROSC) rate, 24-hour survival rate and survival rate of discharge were evaluated. RESULTS: Compared with unarmed stabilization device group, ROSC rate (29.1% vs. 9.9%, χ2 = 9.691, P = 0.002), 24-hour survival rate (20.9% vs. 6.2%, χ2 = 7.649, P = 0.006) and survival rate of discharge (12.8% vs. 3.7%, χ2 = 4.485, P = 0.035) were significant increased in armed stabilization device group. CONCLUSIONS: CPR with stabilization device during ambulance transport could effectively ensure quality of CPR and improve prognosis in OHCA.
