  • 摘要:
    目的 探讨重型颅脑损伤患者营养状况及住院时间(LOS)与相位角(PA)的关系。
    方法 选取神经外科收治的患者100例格拉斯哥昏迷量表(GCS)评分≤8分作为研究对象。通过人体成分分析检测以及采血化验, 获得患者细胞内外水分、骨骼肌、PA、预后营养指数(PNI)以及LOS指标。根据PA值将患者分为低PA组(n=42)和正常PA组(n=58)。比较2组人体成分相关指标、PNI和LOS, 分析PA与各指标的相关性，分析患者发生营养不良的影响因素。
    结果 低PA组患者细胞内水分、身体总水分、身体细胞含量、PNI低于正常PA组, LOS长于正常PA组，差异有统计学意义(P < 0.05)。PA与细胞内水分、细胞外水分、身体总水分、骨骼肌、身体细胞含量、骨矿物质含量、基础代谢率、PNI呈正相关(P < 0.05), PA与LOS呈负相关(P < 0.05)。PA(OR=5.441, P=0.001, 95%CI: 2.011~14.719)和LOS(OR=8.373, P < 0.001, 95%CI: 3.079~22.765)是患者发生营养不良的影响因素。
    结论 PA与重型颅脑损伤患者营养状况以及LOS显著相关。

     

    Abstract:
    Objective To investigate the relationships of nutritional status and length of stay (LOS) with phase angle (PA) in patients with severe craniocerebral injury.
    Methods A total of 100 patients Glasgow Coma Scale (GCS) score ≤8 points admitted outside the department of neurology were selected as study objects. Body composition analysis and blood samples were used to determine the intracellular and extracellular water content, skeletal muscle, PA, prognostic nutritional index (PNI) and LOS. Patients were divided into low PA group (n=42) and normal PA group (n=58) based on PA values. Body composition related indexes, PNI and LOS were compared between the two groups. The correlation between PA and each index was analyzed. The influencing factors of malnutrition were analyzed. The influencing factors of malnutrition were analyzed.
    Results Intracellular water, total body water, body cell content and PNI in the low PA group were significantly lower, and LOS was significantly longer than that in the normal PA group (P < 0.05). PA was positively correlated with intracellular water, extracellular water, total body water, skeletal muscle, body cell content, bone mineral content, basal metabolic rate and PNI (P < 0.05), while PA was negatively correlated with LOS (P < 0.05). PA (OR=5.441, P=0.001, 95%CI, 2.011 to 14.719) and LOS (OR=8.373, P < 0.001, 95%CI, 3.079 to 22.765) were the influential factors in the occurrence of malnutrition.
    Conclusion PA is significantly correlated with nutritional status and LOS in patients with severe craniocerebral injury.
