目的:建立一种适用于国内成人肠外营养液(TNA)渗透压摩尔浓度的预测公式。方法:对2019年7月至9月北京协和医院药剂科配制的2 480份个体化成人TNA，使用全自动冰点渗透压测定仪测定其渗透压摩尔浓度，并对结果进行Pearson n χ2检验及多元线性回归分析，建立TNA渗透压摩尔浓度预测公式。n 结果:TNA样品渗透压摩尔浓度平均值为(1 164.20±252.59)mOsm/kg。最佳渗透压摩尔浓度拟合公式为(9.66A＋7.88G＋3.52F＋36.4Na＋27.55K＋3.38P＋7.46W-250)/V。结论:预测公式能更准确快速预测TNA渗透压摩尔浓度，为临床TNA处方制定、审核及给药途径选择提供参考。“,”Objective:To establish a predictive equation for the osmolarity of parenteral nutritional prescription in China.Methods:From July 2019 to September 2019, 2 480 individualized samples of 328 different parenteral nutritional prescriptions (adult) of Peking Union Medical College Hospital were collected, and the osmolarity of parenteral nutritional solution samples was determined by a freezing point reduction method. Pearson n χ2 test and a multiple linear regression analysis were utilized to establish a prediction equation for the osmolality of parenteral nutritional solution.n Results:The average osmolarity of parenteral nutritional prescription was (1 164.20 ± 252.59) mOsm/kg, and the best fitting equation was (9.66A+ 7.88G+ 3.52F+ 36.4Na+ 27.55K+ 3.38P+ 7.46W-250)/V.Conclusion:The osmolarity is determined accurately and effectively by the fitting equation, which provide a benefit reference for the formulation, review and selection of clinical parenteral nutrition prescription especially in China.
