A computerized glucose adjustment system for intravenously controlling a patient's blood chemistry on a real time basis, said system comprising: a catheter to be placed within the patient's venous system; a glucose sensor attached to said catheter so as to be in contact with the patient's bloodstream to measure the patient's current blood glucose level denoted Xt; a pump connected to a source of insulin and configured for distributing insulin into the patient's bloodstream through said catheter, the pump also being connected to a source of dextrose and configured for distributing dextrose into the patient's bloodstream through the catheter; a programmable computer processor in electronic communication with said sensor and said pump, said processor configured for receiving an electronic signal from said sensor for calculating the patient's real time average blood glucose level over a specified time period; and a glucose control module stored in said processor for sending output signals to said pump for controlling the rate at which said pump distributes insulin and dextrose into the patient, wherein said glucose control module is configured to (i) calculate and store a current average blood glucose level Xa over said specified time period and to calculate the category for the current average glucose measurement Xa from among pump controlling command categories defined by glucose value ranges along a glucose value continuum determined by the amount the current average blood glucose level Xa differs from a normal blood glucose range between Xmin and Xmax set by a user; (ii) compare the current average blood glucose level Xa to a prior average blood glucose level Xb to determine the rate at which the average blood glucose level is changing over time; and (iii) iteratively adjust the dextrose flow rate (Dexf) and insulin flow rate (INSf) into the patient's body according to the calculated category, the rate at which the average blood glucose level is changing, and the weight-based previous flow rates of insulin (INSfp) and of dextrose (Dexfp) effective at the time the glucose measurement was taken, to adjust the average blood glucose level closer to said normal blood glucose range. a catheter to be placed within the patient's venous system; a glucose sensor attached to said catheter so as to be in contact with the patient's bloodstream to measure the patient's current blood glucose level denoted Xt; a pump connected to a source of insulin and configured for distributing insulin into the patient's bloodstream through said catheter, the pump also being connected to a source of dextrose and configured for distributing dextrose into the patient's bloodstream through the catheter; a programmable computer processor in electronic communication with said sensor and said pump, said processor configured for receiving an electronic signal from said sensor for calculating the patient's real time average blood glucose level over a specified time period; and a glucose control module stored in said processor for sending output signals to said pump for controlling the rate at which said pump distributes insulin and dextrose into the patient, wherein said glucose control module is configured to (i) calculate and store a current average blood glucose level Xa over said specified time period and to calculate the category for the current average glucose measurement Xa from among pump controlling command categories defined by glucose value ranges along a glucose value continuum determined by the amount the current average blood glucose level Xa differs from a normal blood glucose range between Xmin and Xmax set by a user; (ii) compare the current average blood glucose level Xa to a prior average blood glucose level Xb to determine the rate at which the average blood glucose level is changing over time; and (iii) iteratively adjust the dextrose flow rate (Dexf) and insulin flow rate (INSf) into the patient's body according to the calculated category, the rate at which the average blood glucose level is changing, and the weight-based previous flow rates of insulin (INSfp) and of dextrose (Dexfp) effective at the time the glucose measurement was taken, to adjust the average blood glucose level closer to said normal blood glucose range.
