Abstract：Objective The gap of survival rate of out -of-hospital cardiac arrest (OHCA) between China and Europe or the United States suggested the chain of survival quality had difference. We, therefore, compared the quality of out-of-hospital cardiac arrest survival chain between Suzhou in China and Strasbourg in French.Methods This retrospective study compared the pre -hospital cardiopulmonary resuscitation ( CPR) and the management of mean arterial pressure, peripheral oxygen saturation, partial pressure of carbon dioxide, blood glucose and body temperature monitored for 48 hours immediately following into intensive care unit ( ICU) admission between 44 comatose survivors of CA admitted ICU of 10 hospitals in Suzhou from 2009 to 2010 ( Suzhou group) and 25 patients in ′Nouvel Hospital Civil'of Strasbourg from 2010 to 2011 ( Strasbourg group) .Results For the quality of pre-hospital emergency, the ratio of bystander CPR was 44%in Strasbourg group and 16%in Suzhou group (P<0.05).The time from cardiac arrest to cardiopulmonary resuscitation (CA-CPR) and the time from cardiac arrest to return of spontaneous circulation ( CA-ROSC) were 5 and 27 min in Strasbourg group compared with 15 and 40 min in Suzhou group ( P <0.01 ) .For the parameters of post -resuscitation bundle, there were significant differences in the percentage of subjects achieving goals recommended for partial pressure of carbon dioxide 6 hours after CA (61% vs 27%; P<0.01) and within 48 hours after CA (59%vs 29%, P<0.01) between Strasbourg and Suzhou group.There were also significant differences in the percentage of cooling (88%vs 57%, P<0.01), of achieving target temperature (84%vs 13%, P<0.01) and of achieving goals recommended for therapeutic hypothermia (44%vs 7%, P<0.01) between Strasbourg and Suzhou group.Conclusion The quality of survival chain for OHCA patients in Suzhou was worse than in Western Europe, especially in the quality of pre-hospital emergency, and we need to also improve the implementation of therapeutic hypothermia in hospital.
