【摘要】目的 探讨危重患者入ICU时基线骨骼肌含量与病情危重程度及预后的相关性。方法 纳入在ICU治疗时间≥48 h的危重患者79例,测量其入ICU时胸部CT第七胸椎(T7)水平横断面胸肌面积(PMA),分析PMA与90 d病死率、90 d内生存率、28 d内非ICU生存日数、28 d内无机械通气生存日数、ICU病死率、院内病死率等指标的相关性。结果 在校正性别、危重症营养风险评分、 Charlson共病指数、血红蛋白等因素后,基线PMA较大患者90 d病死率更低,90 d内生存率更高,28 d内非ICU生存日数更多,院内病死率也更低,与基线PMA较小患者比较差异均具有统计学意义(P均< 0.05)。结论 危重患者入ICU时的基线骨骼肌含量可用于预测病情严重程度、需要体外生命支持和ICU治疗的时间和临床预后。

【Abstract】Objective To investigate the correlation between the baseline skeletal muscle mass and the severity and prognosis of critical patients in ICU. Methods Seventy-nine patients admitted to ICU for≥48 h were recruited in this study. The (T7) level cross-sectional pectoral muscle area (PMA) upon admission to ICU was measured. The correlation between PMA and 90 d mortality, survival rate to 90 d, ICU-free survival to 28 d, ventilator-free survival to 28 d, ICU mortality and hospital mortality was analyzed. Results After the adjustment of gender, NUTRIC score, Charlson comorbidity index (CCI) and hemoglobin, patients with larger baseline PMA still obtained significantly lower 90 d mortality, higher survival rate to 90 d and ICU-free survival to 28 d, and lower hospital mortality compared with their counterparts with smaller baseline PMA (all P < 0.05). Conclusions Upon admission to ICU, baseline skeletal muscle mass of critical patients can be utilized to predict the severity of illness, the duration of ventilator use, the length of ICU stay and clinical prognosis of patients.

危重患者在ICU治療期间、好转转出ICU后甚至出院后会存在严重程度和持续时间不等的骨骼肌功能障碍,包括骨骼肌萎缩和虚弱,被称为ICU获得性衰弱,其与患者病死率、机械通气脱机困难及ICU再入院的相关性已有较多论
证[1-2]。近年来,整体临床诊疗水平显著提升使众多慢性疾病患者的生存期明显延长,社会人口老龄化现象也更为普遍,有国外学者注意到部分患者因疾病危重状态而入ICU前已存在不同程度肌肉损失,入ICU时的骨骼肌基线状态与病死率及其他临床结局存在关联性,但目前相关报道较少,而针对国人的相关分析更为缺乏。在本研究中,我们采集危重患者入ICU时经胸部CT分析所得的胸肌面积作为骨骼肌含量基线信息,分析其与90 d病死率及其他次要临床研究终点之间是否存在相关性,探讨是否能通过测量危重患者入ICU时的基线胸肌面积进一步判断患者病情严重程度及临床预后。……
