A study on the clinical application of all-in-one-mixed and pre-mixed parenteral nutrition preparations / 中华普通外科杂志

ABSTRACT

ObjectiveTo evaluate the parenteral nutrition formula's character of all-in-one-mixed preparation and pre-mixed preparation applied for hospitalized patients in China.MethodsWe collected parenteral nutrition (PN) prescriptions in hospitalized patients with various diseases at dispensing centers of 6 hospitals in different areas of China. Statistic analysis was made by nutrients application, total liquid, nonprotein calories, total nitrogen, ratio of non-protein calories and total nitrogen, and ratio of glucose and fat. A comparison was made between all-in-one-mixed and pre-mixed preparation as to all the indices.Results The nutrients supply in all-in-one-mixed PN preparation, as well as in the pre-mixed PN preparations of 3 different energy degrees can meet the basic nutrition requirements of most patients. The total nitrogen supply in all-in-one-mixed PN prescriptions meets nutrition requirements in most patients, but the ratio of non-protein calories and total nitrogen[( 180-250) 1]and the ratio of glucose and fat (0. 56-1.26)were significantly different from what a doctor would recommend[( 100-150) 1, 1.0]. While the ratios in the pre-mixed PN preparation on 3 different energy degrees are more consistent with recommeded values,which are at 167 and 0. 8 respectively.ConclusionsAll-in-one-mixed and pre-mixed PN preparation have their own individual advantages and limits, and both of them can meet the requirements of most hospitalized patients. More attention should be paid to the nutrients proportion when doctors prescribe all-in-one-mixed PN preparations.
