The Use of Mechanical Cardiopulmonary Resuscitation May Be Associated With Improved Outcomes Over Manual Cardiopulmonary Resuscitation During Inhospital Cardiac Arrests

We aimed to investigate the impact of mechanical cardiopulmonary resuscitation devices over manual cardiopulmonary resuscitation on outcomes from inhospital cardiac arrests. DESIGN: Restrospective review. SETTING: Single academic medical center. PARTICIPANTS: Data were collected on all patients who suffered cardiac arrest from December 2015 to November 2019. MAIN OUTCOMES AND MEASURES: Primary end point was return of spontaneous circulation. Secondary end points included survival to discharge and survival to discharge with favorable neurologic outcomes. RESULTS: About 104 patients were included in the study: 59 patients received mechanical cardiopulmonary resuscitation and 45 patients received manual cardiopulmonary resuscitation during the enrollment period. Return of spontaneous circulation rate was 83% in the mechanical cardiopulmonary resuscitation group versus 48.8% in the manual group (p = 0.009). Survival-to-discharge rate was 32.2% in the mechanical cardiopulmonary resuscitation group versus 11.1% in those who received manual cardiopulmonary resuscitation (p = 0.02). Of the patients who survived to discharge and received mechanical cardiopulmonary resuscitation, 100% (n = 19) had a favorable neurologic outcome versus 40% (two out of five) of patients who survived and received manual cardiopulmonary resuscitation (p = 0.005). CONCLUSIONS: Our findings demonstrate a significant association of improved outcomes with mechanical cardiopulmonary resuscitation over manual cardiopulmonary resuscitation during inhospital cardiac arrests. Mechanical cardiopulmonary resuscitation may improve rates of return of spontaneous circulation, survival to discharge, and favorable neurologic outcomes.
