Abstract:
Objective To investigate the changes of tissue factor(TF)and tissue factor pathway inhibitor(TFPI)at different time points after in-hospital eardiopulmonary resuscitation(CPR).and to explore the role of TF and TFPI in CPR.Method From September 2005 to September 2007,24 patients,who suffered from cardiac arrest,were selected from the of emergency medicine department,The First Affiliated Hospital,Wenzhou Medical College.The selected patients were older than 16 years old and had identified cardial :arrest time.All patients were randomly classified into two groups:those who had retum of spontaneous circulation(ROSC)(n:12)and those mthom ROSC(n=12).Ten normal healthy volunteers served as control subjects(n=10).Etiology of the car.diac arrest and clinical characteristics during eardiopulmomry resuscitation were emestered.Serial levels of"IF and TFPI at different time points of 30 min,60 min,6 h,24 h,48 h after CPR were measured by enzyme linked immunosorbent assay(ELISA)after eardarrest and CPR.Data Were expressed as mean±standard deviation twotailed t test and ANOVA and four flod table chi-square test were used for eomparisoll in SPSS 11.5 software,and chaangs were considered as statistically significant if P value was less than 0.05.Results Inpatients with ROSC.TF obviously increased at 30 min after CPR.reached peak at 6 h.1F levels in patients without ROSC wer higher compared to those of the control group and ROSC at the same time point.The levels of TPFI had no significantly differentce at 50 min after CPR,and TFPI,obviously elevated at 60 min after CPR in ROSC group compared to those ofthe control group and without-ROSC group.In comparison with control group,the ratio of TF/FPI at 30 min after CPR in without-ROSC group and ROSC group were marked elevated.The ratio of in without-ROSC group showed marked devations eompare,t to that of ROSC group.In R()sC group.the ratio of THFI peaked at 6 h after CPR and descended a after CPR.Conclusions'11le 1F and TFPI level8 after CPR in patients with in-hospital cardiac obviously increase.The levels of TF and TF/TFPI at 30 min after CPR can be used for predicting the prognosis of patients with in-hospital cardiac arrest.
