Mechanical compression devices could solve manual resuscitation shortcomings and help maintain its quality. This study compared the mechanical chest compression device LUCAS-2 with manual compressions in out of hospital non traumatic cardiopulmonary resuscitation.
The study randomized 4471 patients (1652 to LUCAS-2 and 2819 to the control group) primary end point was 30 day survival and between secondary end points was return of spontaneous circulation and neurological function at 3 months.
At 30 days, survival rates were similar in both groups (5,1% vs. 5,8%, OR 0,87, IC de 95% 0,61-1,23) even though neurological outcomes were better with manual compression (3,9 vs. 5,9%, OR 0,65, IC 95% 0,45-0,96).
Conclusion
There was no evidence of survival rate increase with mechanical resuscitation compared to manual compressions during out of hospital cardiopulmonary resuscitation. It is not possible to recommend the LUCAS-2 to replace manual compressions for routine use.
