1. A computerized glucose adjustment system for intravenously controlling a patient's blood chemistry on a real time basis, said system comprising: a glucose sensor measuring a patient's glucose level; a pump connected to a source of insulin and a source of dextrose for distributing insulin and dextrose into a patient's bloodstream; a computer processor in electronic communication with said sensor and said pump, said processor receiving an electronic signal from said sensor for calculating the patient's real time average glucose level over a specified time period; a glucose control module stored in said processor, said glucose control module (i) determining where the patient's real time average blood glucose level lies along a continuum of glucose values; (ii) tracking a rate at which the average blood glucose level is changing over time and (iii) iteratively adjusting the dextrose flow rate and insulin flow rate into the patient's body to adjust the real time average glucose level closer to a known normal glucose range by sending output signals to said pump and controlling a pump rate at which said pump distributes insulin and dextrose into the patient, wherein the real time average blood glucose level calculated in the processor is a running average (Xa) over a specified time period, wherein the computer processor records a prior running average blood glucose level (Xb) for a prior time period previous to a just completed specified time period, wherein the glucose control module compares the running average glucose level (Xa) to the prior running average glucose level (Xb) to track a real time average blood glucose level rate of change, wherein said glucose control module comprises pump controlling commands divided into categories, that determine an extent to which a dextrose flow rate and an insulin flow rate from said pump are adjusted; and wherein said processor assigns each running average blood glucose level (Xa) to one of said categories by grouping (A) a difference between a most recently calculated running average blood glucose value (Xa) and a range of Xmin to Xmax; (B) said real time average blood glucose level rate of change; (C) a value of a previous weight-based insulin flow rate; and (D) a value of a previous weight-based dextrose flow rate, and wherein said processor groups A, B, C, and D each time a new average glucose level Xa is calculated, and wherein said glucose control module determines an extent to which a dextrose flow rate and an insulin flow rate from said pump are adjusted by said pump controlling commands in said one of said categories.
