摘要目的 开发嵌入医院信息系统的肠外营养智能辅助医嘱系统,为医生合理开具肠外营养医嘱提供便利.方法 基于产生式规则,设置肠外营养医嘱的综合数据库、知识库、控制系统,设计开发肠外营养智能辅助医嘱系统,自动计算患者个体化能量需求并与医生开具的肠外营养医嘱进行比对,自动计算对“全合一”肠外营养液稳定性有决定性因素的阳离子浓度并进行控制.结果 该系统可智能计算患者的个体化能量需求,对总能量、糖脂比、热氮比、离子浓度、液体体积进行超值警示,对影响破乳的阳离子浓度进行控制.结论 肠外营养智能辅助医嘱系统可有效解决能量计算、肠外营养“全合一”系统稳定性的问题,促进肠外营养在医院的合理应用.

abstractsObjective To develop an intelligent assist order system for parenteral nutrition and embed it into hospital information system,so as to facilitate rational prescription of parenteral nutrition.Methods Comprehensive database,knowledge base and control system of parenteral nutrition orders were set up based on production rule.An intelligent assist order system for parenteral nutrition was designed and developed.Individual energy demand of patients were calculated automatically and compared with doctors' orders of parenteral nutrition.Cation concentration was calculated automatically and controlled for the stability of "all-in-one" parenteral nutrition admixture.Results This system achieved successful and fast calculation of individual energy demand,over-standard warning of total energy,the ratios of carbohydrates to lipids and non-protein calories to nitrogen,ion concentration,and liquid volume.It also controlled the cation concentration,thus avoiding demulsification.Conclusions The intelligent assist order system for parenteral nutrition can solve the problems of energy calculation and ensure the stability of "all-in-one" parenteral nutrition admixture.As a result,it can improve the utilization of parenteral nutrition in hospital.
