Abstract 11888: Mechanical Circulatory Support Increases Return of Spontaneous Circulation in Patients Receiving Mechanical Chest Compressions for Cardiac Arrest in the Cardiac Catheterization Laboratory
Introduction: In the cardiac catheterization laboratory (CCL), use of a mechanical chest compression (MCC) device allows acute cardiac life support (ACLS) and percutaneous interventions to occur simultaneously. Use of MCC in the CCL ensures adequate chest compressions without relying on manual compression providers. This is especially important in the context of recent studies that have shown that therapies offered in the CCL increase survival in patients with cardiac arrest. Furthermore, mechanical circulatory support (MCS) has been shown to improve outcomes of patients with cardiac arrest, but it is not known whether emergent, percutaneous MCS initiation provides clinical efficacy in patients undergoing MCC-assisted ACLS in the CCL.
Methods: We performed a retrospective analysis of patients who received MCC-assisted ACLS in the CCL at our institution between April 2014 and February 2016. Baseline characteristics, resuscitation characteristics, and clinical outcomes were compared between patients who were treated with MCS and those who were not. Unpaired two-sample t-tests were used to compare continuous variables. Fisher’s exact test was used to compare categorical variables.
Results: Thirty-one patients received MCC-assisted ACLS in the CCL. Twenty-two patients (71%) were treated with MCS (14 external cardiac life support (ECLS), 3 Impella, 5 intra-aortic balloon pump (IABP)). Patients who received MCS were significantly more likely to achieve return of spontaneous circulation (ROSC) than those who did not receive MCS (95% v 22%, p = 0.00). Thirty-day survival was more common in the group receiving MCS (Table 1). The majority of patients who received MCS suffered cardiac arrest either outside the hospital or in the emergency department.
Conclusions: The addition of percutaneous MCS to MCC-assisted ACLS increased the rate of ROSC. These findings support the use of emergent percutaneous MCS during MCC-assisted ACLS in the CCL.
