【摘要】:目的:研究幾種常見(jiàn)電解質(zhì)對(duì)新生兒腸外營(yíng)養(yǎng)液穩(wěn)定性的影響。方法:室溫(25℃)下考察僅含一價(jià)或二價(jià)離子的電解質(zhì)(10%氯化鈉注射液、10%氯化鉀注射液、25%硫酸鎂注射液、葡萄糖酸鈣注射液)的營(yíng)養(yǎng)液和同時(shí)含一價(jià)、二價(jià)離子的電解質(zhì)的營(yíng)養(yǎng)液混合放置24 h內(nèi)的外觀變化,測(cè)定其p H和不溶性微粒數(shù)、乳粒粒徑大小及粒度分布(多分散指數(shù),PDI)。結(jié)果:加入電解質(zhì)的營(yíng)養(yǎng)液的p H均大于5,均符合質(zhì)量要求;外觀均未出現(xiàn)沉淀、絮凝、變色等現(xiàn)象;僅含一價(jià)離子的電解質(zhì)的營(yíng)養(yǎng)液放置24 h出現(xiàn)少量掛壁現(xiàn)象,但未出現(xiàn)破乳現(xiàn)象;僅含二價(jià)離子的電解質(zhì)的營(yíng)養(yǎng)液放置24 h出現(xiàn)少量掛壁現(xiàn)象,且出現(xiàn)破乳現(xiàn)象;同時(shí)含一價(jià)和二價(jià)離子的電解質(zhì)營(yíng)養(yǎng)液放置12 h出現(xiàn)少量掛壁現(xiàn)象,放置24 h掛壁現(xiàn)象更明顯且出現(xiàn)微量破乳現(xiàn)象,同時(shí)出現(xiàn)粒徑大于5μm的乳粒和粒徑大于25μm的不溶性微粒,且平均粒徑和PDI值均比前2種情況更高(P0.05)。結(jié)論:新生兒腸外營(yíng)養(yǎng)液中含一價(jià)和二價(jià)離子的電解質(zhì),特別是含二價(jià)離子的電解質(zhì)加入越多,其穩(wěn)定性越差,表現(xiàn)為乳粒粒徑增大、不溶性微粒數(shù)增加。
