Abstract
An operational computerized system to aid clinicians in the design of total parenteral nutrition regimes is reported. Two computer programs are described. The 'Requirements' program uses patient data and the results of blood and fluid excretion analyses to calculate the nutritional requirements for a period of 24 hours. Accepted formulae are used in these calculations. The 'Bottle Selection' program fits an intravenous bottle regime to the patient requirements from a standard set of commercially available intravenous feeding solutions. The system has been well accepted by the clinical staff who are free to accept, modify or reject a regime. Financial savings have been noted by the pharmacy who can plan for a faster turnover of a smaller range of solutions. The programs have been used routinely on a programmable calculator and have been written in CORAL for a Ferranti Argus 700E computer.
