Intensive care medicine relies on the fast and flawless organization of data. In addition, control of therapy requires many calculations. The computer program presented here improves and facilitates documentation of medical prescriptions on the ICU. The program can be run on affordable personal computers. Fluid balances can be managed easily while the program calculates the intake of calories, carbohydrates, protein, fat and electrolytes in the background. On entry of medications suggestions for the pediatric dosage are given automatically. Use of this program provides a flexible way of reusing and editing prescriptions, thus adding up to a time-gaining and precise way of writing intensive care prescriptions.
