Changes of Thyroid Function in Patients with Cardiac Arrest after Successful Resuscitation
This paper analysesthe changes of thyroid function in patients with cardiac arrest after successful resuscitation. Thirty five patients with cardiac arrest who survived at least 12 hours after successful CPR were included to measure TT3, TT4, free T3 (FT3), free T4 (FT4), thyroid stimulating hormone (TSH) levels and blood lactate (LAC) in peripheral serum. According to the results of Lac, the patients were divided into two groups: Lac elevation group and lac control group. The thyroid hormone levels of the two groups were compared, and the correlation between lac and thyroid hormone was analyzed. The incidence of NTIS was 57.14%. 26 cases (74.29%) in the lac increased group and 9 cases (25.71%) in the lac control group. The levels of TT3, FT3 and TSH in the lac group were lower than those in the lac group, but the difference was not significant, and the statistical significance standard was not applicable (P > 0.05). TT3, FT3 and TSH were negatively correlated with lac, r were - 0.480, - 0.517 and - 0.429, respectively, which were statistically significant. TT4 and FT4 were not related to lac, and R was 0.021 and - 0.018, respectively. The difference was not significant, and the statistical significance standard was not applicable (P > 0.05). After successful resuscitation, the thyroid function of patients with cardiac arrest changes significantly. After successful cardiopulmonary resuscitation, the level of thyroid hormone decreases. The more serious the damage of circulatory metabolism, the more obvious the decline of thyroid function.
