某三级甲等医院院肿瘤患者肠外营养处方使用情况的横断面调查

A cross-sectional study on the use of parenteral nutrition presciptions in patients with cancer in a tertiary hospital

目的 通过对肠外营养处方的综合分析,了解其使用情况和处方存在的问题,为规范肠外营养的临床应用提供实践指导.方法 对某三级甲等医院住院部肿瘤患者的肠外营养处方进行为期1个月的横断面调查,对使用肠外营养患者的一般情况、 肠外营养制剂的种类和肠外营养处方涉及的热氮比、 糖脂比、 非氮热量、 液体量等指标进行分析和评价.结果 共收集肠外营养处方528份,肠外营养使用存在不合理现象,处方中三大营养素不全处方308份,占比高达58.3%,热氮比（100-200）：1处方170份,占32.2%,糖脂比（1-2）：1处方109份,占20.6%,多数未在规定范围之内.结论 肠外营养的合理规范应用亟需引起临床医师的重视,有必要成立临床营养支持小组对肠外营养的正确使用进行相应的干预和指导.

Objective To investigate the application of the parenteral nutrition prescriptions for tumor patients in a tertiary hospital .Methods In this cross-sectional study , the parenteral nutrition prescriptions of all tumor inpatients in a tertiary hospital were collected from May to June in 2015 .The general data of patients who had used parenteral nutrition , the types of parenteral nutrition products , as well as the ratio of energy to nirogen （ E/N） , glucose/lipid （ G/L） ratio, non-protein energy to nitrogen ratio , and liquid volume were recorded and analyzed .Results Parenteral nutrition prescriptions were collected from 528 patients and showed high irrationality.The nutrient insufficiency rate was nearly 58.3%.The E/N （100：1 -200：1） accounted for 32.3%and the G/L （ 1：1 -2：1 ） 20.6%.Conclusions The rational application of parenteral nutrition should be a priority in clinical settings .A clinical nutrition supporting team may be established in tertiary hospitals to guide the appropriate use of parenteral nutrition .
