898份全营养混合液医嘱的合理性分析

目的考察某院全营养混合液医嘱的特点及合理性。方法收集某院2010年9月至2011年9月全营养混合液医嘱，统计患者性别、年龄、临床诊断、使用天数，并评定全营养混合液的稳定性和营养参数的合理性。结果共收集了451例患者，男女比2．22：1，年龄（63．5±15．4）岁，临床诊断以外科疾患为主，使用天数（11．2±12．7）d；共涉及898份医嘱，约1／3不符合稳定性标准，营养参数特征是低糖高脂，总能量、氨基酸、液体量相对低。结论该院部分全营养混合液医嘱不合理，需进一步改进。

Analysis on rationality of 898 total nutrient admixture orders

AIM To investigate the feature and rationality of the total nutrient admixture（TNA） orders in one hospital. METHODS The TNA orders from September 2010 to September 2011 were selected. The patients＇ gender, age, clinical diagnoses, medication duration were recorded. And the stability, nutrient requirement parameters of the for- mulations were evaluated. RESULTS In 451 selected patients, the male to female ratio was 2.22 ： 1, the average age was （63.5 ± 15.4） years, the majority of clinical diagnoses were surgical diseases, and the mean medication duration was （11.2 ± 12.7） d. Of the total of 898 orders, about one third did not meet the stability standards. The nutrient re- quirement parameters showed that the carbohydrate content was low and the fat content was high, the supply of total calo- ries, amino acids and fluid volume were relatively low. CONCLUSION A part of TNA orders were irrational, and the application of the drugs still needs to be improved.
