2025
This video demonstrates the effect of continuous drug infusion into the mouse brain on blood glucose levels. Glucose metabolism is assessed by collecting blood from a fasted mouse's tail and measuring glucose levels before and after oral glucose administration. Insulin tolerance is evaluated by injecting insulin in the mouse, with glucose levels recorded at specific intervals.

FAQs
The delivered glucose amount rises when the dextrose concentration or infusion rate increases. Dividing that delivery by body weight and time expresses it as mg/kg/min, allowing glucose provision to be considered relative to the individual rather than as a raw infusion volume. This normalization supports more consistent assessment of metabolic support across patients.
GIR provides an estimate of the glucose available for cellular uptake and energy metabolism. A calculated rate describes the intravenous input, but clinicians still need blood-glucose measurements to evaluate glucose control. Considering delivery and measured glucose together helps assess whether metabolic support is appropriate without overlooking excessive delivery or inadequate control.
GIR quantifies the glucose being administered intravenously, whereas blood glucose monitoring measures the glucose level present in the circulation. These values answer different clinical questions: one describes treatment input and the other reflects glucose control. Using both helps clinicians evaluate the relationship between prescribed delivery and observed glucose status.
Calculation requires the dextrose concentration, infusion rate, and the patient’s body weight, with time expressed consistently so the result can be reported in mg/kg/min. After calculating the rate, clinicians monitor blood glucose and reassess therapy as needed. This workflow connects the prescribed infusion with its metabolic and glucose-control effects.
In neonatal hypoglycemia, GIR provides a weight-adjusted way to quantify intravenous glucose support. It allows clinicians to relate the delivered amount to concurrent blood-glucose measurements and to adjust therapy when control is inadequate or delivery becomes excessive. Expressing support relative to body weight is particularly important when infusion volumes alone may be misleading.
For patients receiving parenteral nutrition or critical care, GIR offers a consistent way to describe intravenous glucose delivery and monitor its metabolic burden. Clinicians can consider the calculated input alongside blood glucose and energy-support needs, then balance adequate provision against risks identified in the overview, including hyperglycemia, hypoglycemia, and excessive metabolic load.
