[Survey on parenteral nutrition preparation variability in pediatrics].

UNLABELLED

The prescription and preparation of paediatric parenteral nutrition in Spain are subject to great variability.

AIM

To identify how paediatric parenteral nutrition is prescribed and prepared in Spain.

MATERIAL AND METHODS

During the first quarter of 2001, a telephone survey was carried out among most of the hospitals in which parenteral nutrition is habitually prepared. The survey included questions on who was in charge of the prescription, the use of different solutions, addition of supplements (carnitine, heparin and glutamine), as well as information on the shelf-life of the mixtures. Subsequently, the results of the survey were compared with the following guidance documents: "Enteral and parenteral nutrition in paediatrics", drafted under the auspices of the Spanish Association for Paediatric Gastroenterology, Hepatology and Nutrition (2000) and the "Guidelines for the use of parenteral and enteral nutrition in adult and paediatric patients"/"Nutrition support practice manual" from the American Society for Parenteral and Enteral Nutrition (1998).

RESULTS

Of the 48 hospitals surveyed, paediatric parenteral nutrition was not prepared in 12 of them. the number of food bags prepared daily correlated directly with the size of the hospital. In all cases, the paediatricians were responsible for prescription. In 87% of the centres, this prescription was customized (i.e. solutions adapted to each individual patient). All of the hospitals used dextrose as the source of carbohydrates and specific amino acid solutions for paediatric medicine. Basically, lipid emulsions with long chain triglycerides were used in 65% of cases and another 19% used physical mixtures of MCT and LCT. Only half of the hospitals routinely used all-in-one mixtures. Inorganic phosphate continued to be used in most cases (78%) versus sodium glycerol phosphate. Vitamins and trace elements were added daily in 65% of the hospitals, with alternate administration in the remainder. In half of the centres, heparin was added to the mixture and carnitine in 27%. For 40% of the centres responding to the survey, the solution had to be used within 24 hours of its preparation; 11% did not indicate the shelf-life.

CONCLUSIONS

Although parenteral nutrition is prescribed by the paediatricians on all occasions, the preparation protocols differ significantly between hospitals. Standardization is exceptional. It is noteworthy that all-in-one mixtures are only used in half of the hospitals surveyed. We suggest the creation of a multidisciplinary working party (pharmacists, paediatricians, neonatologists) in order to draw up protocols for the preparation of paediatric parenteral nutrition.
