Abstract:
OBJECTIVE:To study the effects of electrolyte on the stability of the neonatal parenteral nutrition. METHODS:Under room temperature(25 ℃),the neonatal parenteral nutrition containing only monovalent or bivalent ion electrolyte(10% So-dium chloride injection,10% Potassium chloride injection,25% Magnesium sulfate injection,and Calcium gluconate injection) and containing both monovalent and bivalent ion electrolyte were investigated by the change of appearance to determine the pH val-ue,insoluble particles and the size and distribution (polydispersity index,PDI) within 24 h. RESULTS:The pH of the nutrition with electrolyte was over 5 and also met the quality requirements;there were no precipitate,flocculation and discoloration in the appearance;the neonatal parenteral nutrition containing only monovalent ion electrolyte appeared a small amount of hanging wall phenomenon for 24 h,but did not appear demulsification phenomenon;the neonatal parenteral nutrition containing only bivalent ion electrolyte appeared a small amount of hanging wall phenomenon and demulsification phenomenon for 24 h;the neonatal paren-teral nutrition containing both monovalent and bivalent ion electrolyte appeared a small amount of hanging wall phenomenon and de-mulsification phenomenon for 12 h and the hanging wall phenomenon was more obvious for 24 h. Meanwhile,a size bigger than 5μm microns and particle size bigger than 25 μm microns of insoluble particles appeared,and both the average particle size and PDI value were higher than those in the previous two situations(P<0.05). CONCLUSIONS:As more and more monovalent and biva-lent ion electrolyte being added into the neonatal parenteral nutrition,especially divalent ion electrolyte,the stability of the neona-tal parenteral nutrition decreases,which behaves as a phenomenon that the size of grains and the number of insoluble particles in-crease.
