continuous infusion anesthesia and allows easy preparation of different volumes which can minimize drug wastage the standardization of rate taught by the present method eases interpretation and mixing resulting in easier application of drugs and increased patient safety an apparatus is desirably used to assist in achieving the objectives of the present invention the device facilitates accurate and efficient conversion to the nonstandard flow rates required for special applications such as neonatal anesthesia and others a computerized mix controller coupled with a computer capable of performing the mixing determination with the necessary operator inputs can mix and dispense the final drug solution into a ready to use bag users of the method and computer may easily convert to the selection nonstandard flow rates required for special situations such as neonatal anesthesia or others where low flow rates may be required premeasured amounts of anesthetic drugs may be dispensed manually or using the computerized mix controller resulting in increased safety to patients due to the standardized drug amounts would be prepared by the manufacturer application_number US 23250294 A description use of a table that has predetermined values can eliminate many of the required steps in preparing the anesthetics to be administered and tables that follow each variable is also defined and explained white proposes the use of clinically determined high and low values for continuous infusion techniques the value for maintenance infusion rates mir in white is determined by multiplying the plasma concentration cp by the clearance cl the cp column gives the high and low values of the range for each agent for the determination in table 2 the high value of cp will always be selected so that the infusion.
