甲状腺激素对危重症患者病情严重程度的评估

目的 探讨甲状腺激素在危重患者的变化及与其严重程度的关系.方法 选择2009年1-12月我院加强监护病房住院的92例合并非甲状腺疾病综合征(NTIS)危重症患者,记录一般情况,计算急性生理和慢性健康状况评分(APACHEⅡ)评分,检测入科次日甲状腺激素.分析甲状腺激素水平和患者病情严重程度之间是否有相关性.结果 脓毒症休克组患者甲状腺激素,三碘甲状腺原氨酸(TT3)(1.16±0.24)nmol/L、甲状腺素总量(TT4)(68.93±24.11)nmol/L、游离三碘甲状腺原氨酸(FT3)(3.76±0.21)pmol/L,游离甲状腺素(FT4)(16.40±2.74)pmol/L,促甲状腺激素(TSH)(1.58±1.01)mU/L低于非脓毒症休克组TT3(1.50±0.25)nmol/L、TT4(91.70±21.90)nmol/L、FT3(4.24±0.45)pmol/L、FT4(17.98±3.28)pmol/L、TSH(2.43±2.76)mU/L,差异均有统计学意义(P均＜0.05).脓毒症休克组FT3、FT4水平与APACHEⅡ评分具有相关性(r值分别为-0.694、-0.613,P均＜0.05).结论 重症患者甲状腺激素水平低,与病情严重程度具有相关性.

The relationship between thyroid hormone levels and the state of severity in critically ill patents

Objective To investigate the thyroid hormone changes and their relationship with the state of severity in critically ill patients. Methods Ninety-two patients with no thyroidal illness syndrome admitted to the ICU from January ,2009 to December,2009 were enrolled in this study. The common situations and the score of acute physiology and chronic health evaluation Ⅱ were assessed on addmission. We measured the thyroid hormone levels on the day after admission and analysed whether thyroid hormone levels were related to disease severity. Results The thyroid hormone levels in septic shock group [TT3 (1.16 ± 0.24) nmol/L, TT4 (68.93 ± 24.11) nmol/L, FT3 (3.76 ± 0.21) prnol/L, FT4 (16.40 ± 2.74) pmol/L, TSH (1.58 ± 1.01) mU/L] were significantly lower than those in non-septic shock [TT3 (1.50 ± 0.25) nmol/L, TT4 (91.70 ± 21.90) nmol/L, FT3 (4.24 ± 0.45) pmol/L, FT4(17.98 ± 3.28) pmol/L, TSH (2.43 ± 2.76) mU/L] (P ＜ 0.05). The serum thyroid hormone levels of free triiodothyronine (FT3) ,free thyroxine (FT4) were related to the score of APACHE Ⅱ in septic shock(P ＜ 0.05).Conclusions The levels of thyroid hormone were significantly lower in critically ill patients than the control group and had positive correlation with the disease severity.
