The diagnostic value of Sonoclot in the diagnosis of heat stoke complicated with DIC and heat stroke / 实用医学杂志

ABSTRACT

Objective To evaluate diagnostic value of Sonoclot in the diagnosis of heat stroke complicated with disseminated intravascular coagulation (DIC). Methods 43 patients with heat stroke and coagulation dysfunction were retrospectively included and divided into 2 groups according to scores by International Society of Thrombosis and Hemostasis (ISTH): DIC dominant group (22 case) and DIC non-dominant group (21case). Regular coagulation tests , routine blood test , D-dimer and Sonoclot tests were performed at admission and their clinical data were compared. Logistic regression analysis was applied to evaluate the relationships between DIC occurrence and Sonoclot parameters. ROC curves were used to evaluate diagnostic value of Sonoclot for the patients with DIC and heat stroke. Results There were no differences in age, sex, central temperature and total hospital stay between the 2 groups except ICU stay, DIC symptoms, outcome, ISTH scores and APACHEⅡscores (P <0.05). ACT and CR correlated with the occurrence of DIC (P < 0.05). The AUC of ACT and ACT combined with CR were 0.854 and 0.877 respectively. The specificity of ACT in predicting DIC was 69.2%with the sensitivity of 90.3%. When combined with CR, both the specificity and the sensitivity were increased to 80.2% and 93.5%, respectively. Conclusions Sonoclot can predict DIC quickly and is effective in the diagnosis of heat stroke patients with DIC.
