Abstract 284: Load-Distributing-Band CPR for Cardiac Arrest Patients Improves Regional Cerebral Oxygen Saturation
Background: Despite advances in therapeutic strategies and improved guidelines, morbidity and mortality rates for out-of-hospital cardiac arrest (OHCA) remain high. Especially, neurological prognosis is one of the most important problems although brain protection therapy for patients with OHCA has greatly improved in recent years due to the development of emergency post-cardiac arrest interventions, for example, mild therapeutic hypothermia, early percutaneous coronary intervention and extracorporeal cardiopulmonary resuscitation (CPR). Recently, Regional cerebral Oxygen Saturation (rSO2) have received attention as a valuation method of cerebral oxygenation. We have reported that conventional chest compression could not improve rSO2 of cardiac arrest patients if they did not get return of spontaneous circulation. It is, however, not determined whether the mechanical CPR device is helpful for improvement of rSO2.
Objective: The purpose of this study is to evaluate the effects of Load-Distributing-Band CPR (LDB-CPR) on rSO2.
Methods: Prospectively, LDB-CPR was performed for OHCA with AutoPulse from arrival to hospital. During mechanical CPR, rSO2 were recorded continuously from the forehead of the patients. CPR for patients with OHCA was performed according to the JRC-guidelines 2010 except for using AutoPulse instead of manual chest compression.
Results: From December 2012 to May 2013, 18 patients with OHCA were included in this study. The mean age was 74.5±13.8 years old. Duration of time from recognition of cardiac collapse to arrival to hospital was 28.7±5.3 min. Before starting of LDB-CPR, rSO2 was 42.6±8.4% (baseline). rSO2 was significantly increased from baseline to 4, 8 and 12-minute after initiating LDB-CPR (46.9±7.3%, 46.2±6.8%, 47.3±6.8%, respectively p<0.05).
Conclusion: LDB-CPR increased rSO2 of cardiac arrest patients.
