Chest Compression Fraction between Mechanical Compressions on a Reducible Stretcher and Manual Compressions on a Standard Stretcher during Transport in Out-of-Hospital Cardiac Arrests: The Ambulance Stretcher Innovation of Asian Cardiopulmonary Resuscitation (ASIA-CPR) Pilot Trial

Abstract

Mechanical CPR on the reducible stretcher during the transport of OHCAs to the ED showed a much higher chest compression fraction than standard manual CPR.

Adult Basic Life Support: 2020 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations

“…The nonrandomized studies reported conflicting results. Two RCTs 260,261 and 3 nonrandomized studies [266][267][268] suggested variable improvements in physiological parameters with mechanical CPR. Four manikin RCTs 254,255,269,270 and 3 nonrandomized manikin studies 257,271,272 suggested that mechanical CPR provided consistent CPR, whereas the quality of manual CPR declined during transport.…”

Compresiones torácicas mecánicas versus manuales en adultos en parada cardiorrespiratoria extrahospitalaria durante su traslado en ambulancia: una revisión sistemática.

“…Asimismo, las variables dependientes analizadas fueron la supervivencia inmediata, la supervivencia al alta hospitalaria y la supervivencia a largo plazo con una situación neurológica favorable según la Escala Glasgow-Pittsburgh Cerebral Performance Category. Entre los estudios incluidos, 6 realizaron las compresiones mecánicas mediante el dispositivo LUCAS-2 (13,15,16,19,20,21) y 2 con el dispositivo AutoPulse® (14,17). Un único estudio utilizó ambos dispositivos mecánicos junto con el dispositivo semiautomático Animax mono (18).…”

“…Un único estudio utilizó ambos dispositivos mecánicos junto con el dispositivo semiautomático Animax mono (18). Las mediciones se realizaron en 4 estudios, con el monitor/desfibrilador LIFEPAK® 12, 15 o X-series® mediante impedancia transtorácica (14,16,17,19). En otros 3 estudios, se registraron en los maniquíes de reanimación Ambu® MegaCode y Resusci Anne® (18,20,21).…”

Association of transport time interval with neurologic outcome in out-of-hospital cardiac arrest patients without return of spontaneous circulation on scene and the interaction effect according to prehospital airway management

“…8,9,11,13 In an environment where EMS plays a limited role in the termination of resuscitation, OHCA patients without return of spontaneous circulation (ROSC) are transferred to the ED with ongoing resuscitation in the ambulance, which may interrupt high-quality cardiopulmonary resuscitation (CPR) and other interventions. 7,[14][15][16] In addition, there have been no previous studies on the difference in TTI effects according to the interventions performed by the EMS on scene before the transport of the OHCA patient. Therefore, it is necessary to consider the impact of TTI on patient outcome in that OHCA patients without ROSC should be transferred to the center where suitable approaches for management are carried out in the appropriate time.…”

“…However, these studies were mainly conducted under a system wherein most patients were treated with the advanced cardiac life support (ACLS) system in the prehospital stage [ 8 , 9 , 11 , 13 ]. In an environment where EMS plays a limited role in the termination of resuscitation, OHCA patients without return of spontaneous circulation (ROSC) are transferred to the ED with ongoing resuscitation in the ambulance, which may interrupt high-quality cardiopulmonary resuscitation (CPR) and other interventions [ 7 , 14 - 16 ]. In addition, there have been no previous studies on the difference in TTI effects according to the interventions performed by the EMS on scene before the transport of the OHCA patient.…”
