[A study of the stability of lipid emulsions in mixtures for peripheral parenteral nutrition].

This study is an attempt to contribute practical information on the stability of the mixtures of parenteral nutrition administered peripherally, using two different brands of lipids and amino acids for peripheral administration, with the addition of polivitamins and calcium. The tests performed included the determination of osmolarity, pH and size of lipidic globule using two methods: Coulter Counter and microscopic interference contrast method. The time factor and conservation temperature were taken into account in the stability of the mixtures.
