The results of CPCR attempts after cardiac arrest (CA) are very poor because of the irreversible brain damage, myocardium damage and other organ damage that may occur within 4 min of no blood flow. Early initiation of CPCR by a bystander is crucial, in order to obtain a low blood flow up to the arrival of the mobile intensive care unit (MICU).
To evaluate the impact of resuscitation by a bystander on the short-term outcome (STO) and long-term outcome (LTO).
A consecutive and prospective study over a period of 5.5 years (1 January 1999–9 July 2004) was conducted. The patients were treated by the MICU of the Academic Hospital of the Vrije Universiteit Brussel (AZ-VUB) onsite and later on in the Emergency Department (ED).
In patients who were initially resuscitated by a bystander before arrival of the MICU, ROSC was achieved in 66 (35.29%) cases, while 114 (60.96%) patients were declared dead on the scene. CPCR was continued during transport to the ED in seven (3.74%) patients. When CPCR was initiated by the MICU, ROSC was achieved in 207 (13.81) patients, and 1278 (85.26%) did not achieved ROSC. CPCR was continued during transport to the ED for 14 (0.93%) patients.
One year after resuscitation, 66 (44.07%) of the patients that were initially resuscitated by a bystander and thereby resumed ROSC were still alive, and 33 (55.93%) were declared dead. Out of the patients that were initially resuscitated by the MICU or the first tier and achieved a ROSC, 20 (15.50%) were still alive 1 year after the event and 109 (84.50%) were dead.
Bystander CPCR plays a crucial role in the chain of survival. Compared with patients that were initially not resuscitated by a bystander, significant differences in the STO and LTO are observed.
