Yu G, Kim YJ, Kim JS, et al. - In this prospective cohort of consecutive non-trauma out-of-hospital cardiac arrest (OHCA) patients who were successfully resuscitated and treated with targeted temperature management, researchers sought to examine the prognostic value of coagulopathy evaluated by repeated thromboelastography (TEG) to predict neurologically intact survival. Individuals with a target temperature of 36℃, no TEG data, and who declined appropriate treatment have been excluded. In total, 125 patients (mean age, 61 years; 63.2% male) have been analyzed. According to findings, TEG tests are available in minutes, and shortened R values or the absence of prolonged LY30 values in the initial process are an early indicator of neurologically intact survival in OHCA patients who are successfully resuscitated.
