Investigation of predictors of bleeding complications in COVID-19 using rotational thromboelastometry (ROTEMCIRCLED LATIN CAPITAL LETTER R): A retrospective study
Health Science Reports(2022)
摘要
Background Hemorrhagic complications in patients with coronavirus 19 disease (COVID-19) are infrequent but associated with a prognosis. This study aimed to elucidate the risk factors for bleeding complications in patients with COVID-19 using rotational thromboelastometry (ROTEM) parameters and blood tests performed at admission. Methods In total, 31 patients with severe COVID-19 treated intensively at Saga University Hospital were included in this study. Patients were divided into two groups according to the presence or absence of hemorrhagic complications. Results from the blood tests performed at admission and during hospitalization, and ROTEM values acquired upon admission, were compared between the two groups. Results There were significant differences in ROTEM values upon admission between the bleeding and non-bleeding groups. Receiver operating curve analysis showed that the area under the curve for prothrombin time international normalized ratio (PT-INR) and extrinsically-activated test with tissue factor (EXTEM) amplitude at 10 min (A10) were 0.82 (0.52-0.92) and 0.81 (0.58-0.93), respectively. Logistic regression analysis with PT-INR and EXTEM A10 as factors calculated an odds ratio of 1.94 (1.04-3.62) and EXTEM A10 0.86 (0.71-1.05) for bleeding complications occurrence. Conclusion ROTEM may be a sensitive predictor for bleeding complications in patients with COVID-19.
