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.
