Plasma zinc levels in premature infants receiving parenteral nutrition. 1978

D D Michie, and F H Wirth

Plasma zinc levels in premature infants receiving parenteral nutrition without supplementation of trace elements were evaluated. The mean +/- SE for plasma zinc concentration prior to the start of parenteral nutrition was 53 +/- 6 microgram/dl. During the first two weeks of parenteral nutrition the levels remained low, but did not change significantly. However, from day 14 through day 32 there was a statistically significant (P less than 0.05), progressive decline in plasma zinc values. Perhaps the shortened gestational periods were etiologic in producing the initial low plasma zinc concentration in these patients. Since low-birth-weight infants apparently have a high requirement for zinc, the reduced growth rates of these patients may be related to their apparent zinc deficiencies.

D010288	Parenteral Nutrition	The administering of nutrients for assimilation and utilization by a patient who cannot maintain adequate nutrition by enteral feeding alone. Nutrients are administered by a route other than the alimentary canal (e.g., intravenously, subcutaneously).	Intravenous Feeding,Nutrition, Parenteral,Parenteral Feeding,Feeding, Intravenous,Feeding, Parenteral,Feedings, Intravenous,Feedings, Parenteral,Intravenous Feedings,Parenteral Feedings
D010289	Parenteral Nutrition, Total	The delivery of nutrients for assimilation and utilization by a patient whose sole source of nutrients is via solutions administered intravenously, subcutaneously, or by some other non-alimentary route. The basic components of TPN solutions are protein hydrolysates or free amino acid mixtures, monosaccharides, and electrolytes. Components are selected for their ability to reverse catabolism, promote anabolism, and build structural proteins.

D015032	Zinc	A metallic element of atomic number 30 and atomic weight 65.38. It is a necessary trace element in the diet, forming an essential part of many enzymes, and playing an important role in protein synthesis and in cell division. Zinc deficiency is associated with ANEMIA, short stature, HYPOGONADISM, impaired WOUND HEALING, and geophagia. It is known by the symbol Zn.
