## What is らくらくTPN?

■概要
本アプリは、栄養設計や輸液プランの検討をサポートするツールです。輸液データを選択し投与量を入力することで、カロリーおよび電解質の計算を簡便に行うことができます。複数の輸液を組み合わせ、計算結果を確認しながら輸液量の調整が可能です。

■対応している輸液の種類：生理食塩液、細胞外液補充液、代用血漿増量剤、低張電解質液、糖液類、PPN（末梢静脈栄養輸液）、TPN（中心静脈栄養輸液）、補正用電解質製剤、アミノ酸製剤、脂肪乳剤

■計算項目：輸液時間(時間)、作成総輸液量(mL)、水分率(%)、総輸液量(mL)、総カロリー(kcal/day)、カロリー(kcal/kg/day)、非蛋白性熱量(kcal/day)、NPC/N比、糖熱量(kcal/day)、脂肪熱量(kcal/day)、アミノ酸熱量(kcal/day)、糖濃度(%)、GIR(mg/kg/min)、糖量(g/day)、脂肪量(g/day)、アミノ酸量(g/day)、Na(mEq/L)、Na(mEq/kg/day)、K(mEq/L)、K(mEq/kg/day)、Ca(mEq/day)、Ca(mg/day)、Mg(mEq/day)、Mg(mg/day)、Cl(mEq/day)、Lactate(mEq/day)、Acetate(mEq/day)、Gluconate(mEq/day)、SO4(mEq/day)、Citrate(mEq/day)、Succinate(mEq/day)、P(mmol/day)、Zn(μmol/day)、HCO3(mEq/day)

■注意事項
本アプリの計算結果は参考値であり、その内容について一切の責任を負いません。実際の使用にあたっては、各輸液製剤の添付文書を必ずご確認のうえ、ご自身の判断でご利用ください。
