Abstract 34: Efficacy Assessment of Arterial Pressure-Based Cardiac Output for Out-of-Hospital Cardiac Arrest
Background: Although patients with post-cardiac arrest syndrome (PCAS) after out-of-hospital cardiac arrest (OHCA) is under hemodynamically volatile state, their hemodynamics might be associated with patients' outcome. FloTrac/Vigileo® operating system is an easy low-invasive technique that can do continuous monitoring on arterial pressure-based cardiac output (APCO) from the arterial pressure curve and can calculate Stroke Volume Index (APCO/Heart rate/Body Surface Area: ml/m2). This device has been already available for evaluating fluid responsibility and continuous cardiac output monitoring during peri- and post-operative periods.
Objective: We aimed to assess the association between APCO values and patients' outcome after OHCA.
Materials and Methods: A prospective observational study was conducted in our center. This study analyzed for adult non-traumatic OHCA patients who achieved return of spontaneous circulation (ROSC) and hospitalized at our intensive care unit to receive post-resuscitation cares during the period from January 1 to March 31 in 2011. FloTrac/Vigileo® operating system was attached for all OHCA patients immediately after they got ROSC at emergency room.
Results: This study registered 22 eligible patients. Of them, 7 cases (32%) were survival to discharge (the survival group). There were no differences in patients' characteristics and cares between the survival group and the non-survival group excluding age (70.0±10.0 vs. 82.3±7.4 years old. P=0.004). However, the mean stroke volume index (ml/m2) for 24-hours after attachment of FloTrac/Vigileo® operating system was significantly higher in the survival group than in the non-survival group (37.9±10.2 ml/m2 vs. 28.2±7.72 ml/m2, P<0.023).
Conclusion: The stroke volume index might be effective to predict outcome from OHCA.
