Comparison of the effectiveness of cardiopulmonary resuscitation before and after using the LUCAS device in in-hospital cardiac arrest

ABSTRACT

Objective@#High-quality chest compressions are consistently delivered by mechanical chest compression devices. This study assesses the feasibility of LUCAS in in-hospital cardiac arrest (IHCA) patients. @*Methods@#This was a single-center, retrospective, before and after clinical study comparing the clinical outcomes of LUCAS cardiopulmonary resuscitation (CPR) in IHCA patients. The return of spontaneous circulation (ROSC) rate and 7-day mortality were evaluated to assess short-term outcomes. Additional outcomes included epinephrine dose, CPR time, and the number of medical workers participating in CPR. @*Results@#The number of medical workers who participated in CPR in the LUCAS CPR group was fewer than in the manual CPR group (manual CPR 9.3 vs. LUCAS CPR 4.5; P=0.001). In IHCA patients, no significant differences were obtained in the ROSC rate (manual CPR 46.4% vs. LUCAS CPR 31.4%; P=0.051) and 7-day mortality (manual CPR 81% vs. LUCAS CPR 86.3%; P=0.434) between the two groups. However, the median CPR time (manual CPR 28.1 vs. LUCAS CPR 42.8; P=0.001) and the epinephrine dose (manual CPR 8.3 vs. LUCAS CPR 13.3; P=0.001) were significantly longer in the LUCAS CPR group than the manual CPR group. @*Conclusion@#Compared to manual CPR, CPR with LUCAS required fewer healthcare workers and had no significant difference in the ROSC rate and mortality in patients with IHCA.
