[Weight monitoring in parenteral nutrition: from theory to practice].

Abstract:

OBJECTIVE:To assess the usefulness of establishing a routine gravimetric as quality assurance after the development of parenteral nutrition (PN) with a gravimetric error less than ± 5%. MATERIAL AND METHODS:Prospective study in which 5 to 8 large volume PN were weighed daily during 2 months and for 4 months all small volume PN, considering this the real weight. The theoretical weight was calculated taking into account the densities, volumes of all products used in processing and the weight of the bags used. The gravimetric error was calculated as a percentage compared to the theoretical weight. RESULTS:168 large volume PN and 42 small volume were weighed, gravimetric errors measures were 1.42% (SD=1.31) and 1.26% (SD=0.64), with a gravimetric error less than 5% in 98,8% and 100% respectively. CONCLUSION:Establishing a routine gravimetric control is an useful strategy that can help to guarantee the quality of the PN development.
