摘要
To study the differences in hemorrhagic and embolic complications among extracorporeal cardiopulmonary resuscitation (ECPR) patients who received and did not receive a loading dose of heparin.This study is a controlled before-after monocentric retrospective study.The emergency department of the Aerospace Center Hospital (ASCH).The authors studied a total of 28 patients who, after a cardiac arrest, underwent ECPR in the emergency department of the ASCH from January 2018 to May 2022.The authors compared the hemorrhagic and embolic complications and prognosis of the 2 groups based on whether they received a loading dose of heparin anticoagulation therapy before catheterization (a loading-dose group and a non-loading dose- group).There were 12 patients in the loading-dose group and 16 in the nonloading-dose group. There was no statistically significant difference in age, sex, underlying diseases, causes of cardiac arrest, and hypoperfusion time between the 2 groups. The incidence of hemorrhagic complications was 75% in the loading-dose group and 67.5% in the nonloading-dose group. The difference between the 2 groups was not statistically significant (p > 0.05). The incidence of life-threatening massive hemorrhage in the loading-dose group was 50%, and in the nonloading-dose group, it was 12.5%. The difference between the 2 groups was statistically significant (p = 0.03). The incidence of embolic complications in the loading-dose group and nonloading-dose group was 8.3% and 12.5%, respectively, and the difference between the 2 groups was not statistically significant (p > 0.05). The survival rates of the 2 groups were 8.3% v 18.8%, respectively, and the difference between the 2 groups was not statistically significant (p > 0.05).In conclusion, in the authors' study of patients undergoing ECPR, administering a loading dose of heparin was associated with an increased risk of early fatal hemorrhage. However, stopping this loading dose did not raise the risk of embolic complications. It also did not lower the risk of total hemorrhage and transfusion.
