RESUMEN
We examined the relationship between measured colloid osmotic pressure (COP), and COP calculated from serum total protein concentration (TP). Serum COP and TP were measured in 40 patients with severe abdominal sepsis. Measured COP values were not significantly different from values calculated using three separate formulas. The correlation rate between measured COP and TP (r = .83, p less than .01) was lower than that between calculated COP and TP (r = .99, p less than .01). All three formulas were fairly reliable. Alternatively, a table of predicted COP values may be useful in severely ill patients.

The purpose of this investigation was the knowledge of certain events related with the intravenous administration of lipids in patients with parenteral nutrition such as tolerance, clearence and changes in the plasmatic lipid fractions and the effect of heparin as capilar lipoprotein-lipase stimulant and of the insulin as lipogenetic hormone. With intralipid the authors observed elevation of serum total lipid, triglicerids and fatty acids; in this patients the fatty acids went up after addition of heparin because triglicerid elucidation but went down after insulin administration which favor the tisular captation of fatty acids. They do not found alteration in serum cholesterol. The results with heparin and insulin suggest a greater and more rapid clearence of plasmatic lipids probably by incorporation of them to the tissues. This feature minimize the risk of exogen hyperlipemia, hyperosmolarity and metabolic acidosis.
