Randomized Controlled Trial Comparative Study Clinical TrialA comparison of two 20% lipid emulsions.
Two different soy oil emulsions (Intralipid and Soyacal) were studied over a 2-week period in a random crossover study to determine if there were clinical or biochemical differences between the two preparations when used in patients requiring total parenteral nutrition (TPN). Each fat emulsion was infused randomly over 1 week and then switched to the other. Eighteen adult patients requiring a minimum of 14 days TPN were studied. ⋯ Analysis of nutritional status, irrespective of lipid infused, showed that the patients who received 56 kcal/kg/day with 37% of the nonprotein calories from lipids (1.8 +/- 0.7 g/kcal/day) were in positive nitrogen balance on 80 of the 101 days studied. No adverse effects could be observed from either lipid emulsion during the short period of TPN used in this study. Both lipid emulsions were efficacious as a caloric source, and no clinical complications or biochemical abnormalities were found from either preparation.

ReviewCentral venous catheter care in parenteral nutrition: a review.
Central venous catheter care in parenteral nutrition has been described in numerous publications. These descriptions include care of both short- and long-term catheters. Important aspects in the prevention of infection in central venous catheters used for parenteral nutrition have included: the method of central venous access, subcutaneous tunneling, dressing change techniques, therapeutic uses of the catheter, and catheter-intravenous tubing connection care. ⋯ The use of heparin to prevent thrombosis and catheter occlusion, and the varying degrees of success obtained, have been described. Medical treatment of the occluded catheter with urokinase may be a necessary alternative to discontinuance of that catheter. Overall consideration of research methods used to reach conclusions for catheter care should be considered in the evaluation of appropriate care in each situation.
