Providing 24-hour nutrient infusions to critically ill patients.
The outcome of critically ill patients receiving total parenteral nutrient (TPN) therapy was evaluated, and the percentage of wasted TPN solutions administered as one-per-day (2- or 3-L) or multiple-per-day (750-mL or 1-L) infusions was determined. Between March 31 and June 1, 1984, all patients who were treated by the nutritional support service (NSS) and who met the study criteria were included in the study. The 24-hour nutrient content of each TPN solution was determined using a published method. Patient outcome was determined using TPN therapy data that were collected from the patients' medical charts and NSS records. To determine waste, all discarded TPN solutions were recorded. A total of 20 patients (10 men and 10 women) were included, representing 23.6% of the 76 patients who received TPN therapy during the study period. Study patients received 24-hour nutrient solutions for a mean of 16.4 +/- 12.9 days and required a mean of 3.9 +/- 4.6 days to reach sufficient metabolic stability to qualify for 24-hour infusions. During the study period, 56 (2.8 +/- 2.5 per patient) orders were changed. The percentage of wasted TPN solutions was low; 4.3% (17 of 1326) multiple-per-day and 1.7% (5 of 292) one-per-day solutions were wasted. Twenty-four-hour TPN solutions can be used successfully in critically ill patient populations.
