# Glucose Infusion Rate (GIR, mg/kg/min)

Calculate the glucose infusion rate GIR (mg/kg/min) for neonatal/pediatric IV nutrition. GIR = (mL/h × Dextrose%) / (Weight kg × 6). Supports D5–D50. Targets: 4–6 for term neonates; < 4 hypoglycemia risk; > 12 hyperglycemia risk. Weight in kg or g. Derived from Adamkin 2009, ASPEN 2013, MDCalc, and Singhal 2018. Not medical advice.

## Overview

Calculate glucose infusion rate (GIR) in mg/kg/min for neonatal and pediatric IV nutrition using weight, dextrose concentration, and infusion rate. The calculator accepts weight in kilograms or grams, supports D5 through D50, and returns GIR with related glucose delivery values and a category. It is not medical advice.

## Inputs

- **Weight** (number): Patient body weight, in the unit selected below.
- **Weight Unit** (select)
- **Dextrose Concentration** (select)
- **Infusion Rate (mL/h)** (number): Dextrose infusion rate in mL/h.
- **Decimal Places** (number)

## When to use

- Estimate glucose delivery during neonatal or pediatric IV nutrition.
- Check how a dextrose concentration and infusion rate relate to patient weight.
- Review whether a calculated GIR falls within a target or higher-risk range.

## How it works

- Enter the patient weight and select kg or g as the weight unit.
- Select the dextrose concentration from D5, D10, D12.5, D25, or D50.
- Enter the dextrose infusion rate in mL/h and choose the preferred decimal places.
- The calculator applies GIR = (mL/h × dextrose%) / (weight in kg × 6) and returns the result in mg/kg/min.

## Use cases

- Neonatal intensive care teams reviewing glucose delivery from an IV dextrose infusion.
- Pediatric nutrition planning that requires weight-based glucose calculations.
- Clinical education and calculation checks for dextrose concentration and infusion rate.

## Frequently asked questions

### What does GIR measure?

GIR measures glucose delivery in milligrams per kilogram of body weight per minute.

### What formula does the calculator use?

It uses GIR = (mL/h × dextrose%) / (weight in kg × 6).

### Can I enter a newborn's weight in grams?

Yes. Select g (newborn), and the calculator converts the weight to kilograms.

### Which dextrose concentrations are supported?

The calculator supports D5, D10, D12.5, D25, and D50.

### What GIR range is commonly used for term neonates?

The stated target range for term neonates is 4–6 mg/kg/min. Clinical interpretation requires professional judgment and monitoring.

- [Absolute Neutrophil Count (ANC) Calculator](https://elysiatools.com/en/tools/absolute-neutrophil-count): Calculate the Absolute Neutrophil Count (ANC) = WBC × (segmented % + band %) / 100. Unit selectable: cells/µL or ×10⁹/L (1 ×10⁹/L = 1000 cells/µL). Adult reference ≥ 1500 cells/µL. Neutropenia risk strata: mild 1000–1500, moderate 500–1000, severe < 500 (agranulocytosis < 200) — high risk of serious infection, and febrile neutropenia is a medical emergency. Clinical uses: chemotherapy cycles typically require ANC ≥ 1500 to proceed and ≥ 500 for discharge from protective isolation; carbimazole/clozapine monitoring; congenital neutropenia workup. Neutrophilia > 7500 suggests bacterial infection, inflammation, steroids, or a myeloproliferative neoplasm. If only segmented % is reported, set band % to 0; if the instrument reports an absolute neutrophil count directly (NE#), this tool is not needed. Based on ASCO/IDSA neutropenia guidance, Boxer ASH 2012, and MDCalc. Not medical advice.
- [Serum Anion Gap (AG) Calculator](https://elysiatools.com/en/tools/anion-gap-calculator): Calculate the serum Anion Gap (AG) to classify metabolic acidosis. Standard formula AG = Na⁺ − Cl⁻ − HCO₃⁻ (mmol/L), or AG = Na⁺ + K⁺ − Cl⁻ − HCO₃⁻ with optional potassium. A high AG (≈ >12, or >20 with K⁺) indicates accumulation of unmeasured anions (lactic acidosis, ketoacidosis, renal failure, and toxins such as methanol/ethylene glycol, salicylates — mnemonic GOLD-MARK). A normal AG (8–12) during metabolic acidosis points to a hyperchloremic (normal-anion-gap) acidosis: diarrhea, renal tubular acidosis, saline resuscitation. A low AG (<3–6) is usually hypoalbuminemia, also hypercalcemia/hypermagnesemia, lithium, cationic IgG paraproteins, or bromide pseudo-hyperchloraemia. Optional albumin correction AG_corrected = AG + 2.5 × (4.0 − albumin g/dL) avoids missing a high-AG acidosis in hypoalbuminemia. Derived from Kraut CJASN 2007, Figge 1998, and MDCalc. Interpret with blood gas and full clinical context. Not medical advice.

Derived from Emmett 2016, Kraut 2007, Rastegar 2007, LITFL, MDCalc, and Adrogué 1998. Not medical advice.
- [Corrected Calcium (Albumin) Calculator](https://elysiatools.com/en/tools/corrected-calcium-albumin): Calculate the albumin-corrected total calcium to avoid missing true hypocalcemia or hypercalcemia in hypoalbuminemia. Conventional formula (calcium mg/dL, albumin g/dL): Ca_corr = Ca + 0.8 × (4.0 − Albumin). SI formula (calcium mmol/L, albumin g/L): Ca_corr = Ca + 0.02 × (40 − Albumin). Roughly 40% of circulating calcium is albumin-bound, so low albumin lowers the measured total without changing the physiologically active ionized fraction. Corrected reference range ≈ 8.5–10.5 mg/dL (2.15–2.60 mmol/L). Low → true hypocalcemia (hypoparathyroidism, vitamin-D deficiency, CKD, hypomagnesemia, citrated transfusion, pancreatitis, sepsis); high → true hypercalcemia (primary hyperparathyroidism, malignancy/PTHrP, myeloma, vitamin-D intoxication, thiazides, immobilization, granulomatous disease). When albumin is markedly abnormal or acid-base is deranged, ionized calcium remains the gold standard. Based on Payne BMJ 1973 and MDCalc. Not medical advice.
- [Corrected QT (QTc) Calculator (Bazett/Fridericia/Framingham)](https://elysiatools.com/en/tools/corrected-qt-bazett-fridericia): Calculate the heart-rate–corrected QT interval (QTc) with three formulae. Bazett (1920): QTc = QT/√RR (classic; over-corrects at high HR, under-corrects at low HR). Fridericia (1920): QTc = QT/RR^(1/3) — more accurate across a wide HR range, preferred for drug/QT studies. Framingham (1992): QTc = QT + 0.154×(1 − RR) — simple linear regression. RR is derived from heart rate (RR = 60/HR) when not provided; QT and QTc in ms. Thresholds: men > 450 ms borderline / > 480 ms prolonged; women > 460 ms borderline / > 480 ms prolonged; > 500 ms markedly prolonged. Derived from Bazett 1920, Fridericia 1920, Sagie/Framingham 1992, AHA 2009, ICH E14, and MDCalc. Not medical advice.
- [Corrected Sodium (Glucose) Calculator](https://elysiatools.com/en/tools/corrected-sodium-glucose): Calculate the glucose-corrected serum sodium to reveal true body tonicity in hyperglycemia. Classic Katz (1973) formula Na_corr = Na + 1.6 × (Glucose − 100)/100 (glucose mg/dL), or Hillier (1999) Na_corr = Na + 2.4 × (Glucose − 100)/100 which is more accurate at very high glucose (Katz tends to underestimate). Glucose unit selectable: mg/dL or mmol/L (reference 5.5 mmol/L). Hyperglycemia shifts water extracellularly and dilutes sodium; the corrected value reflects the real water balance. Corrected Na < 135 indicates true hyponatremia (DKA/HHS with free-water excess, SIADH, GI/renal losses); > 145 indicates true hypernatremia (common in HHS, signals free-water deficit and guides replacement). Derived from Katz NEJM 1973, Hillier 1999, Adrogué NEJM 2000, and MDCalc. Not medical advice.
- [Creatinine Clearance Calculator (Cockcroft-Gault)](https://elysiatools.com/en/tools/creatinine-clearance-cockcroft): Estimate creatinine clearance (CrCl) with the Cockcroft-Gault equation: CrCl (mL/min) = \[(140 − Age) × Weight(kg)\] / \[72 × SCr(mg/dL)\] × 0.85 if female. Choose the weight basis: Actual Body Weight (ABW), Ideal Body Weight (IBW, Devine 1974), or Adjusted Body Weight (AdjBW = IBW + 0.4 × (ABW − IBW), for obese patients). Optional SCr floor at 1.0 mg/dL for elderly / low-muscle-mass patients. Returns an UN-indexed CrCl in mL/min — the value drug-dosing tables use (for BSA-indexed eGFR use MDRD or CKD-EPI). Derived from Cockcroft & Gault, Nephron 1976. Valid for stable renal function in adults. Not medical advice.
- [eGFR Calculator (MDRD Simplified)](https://elysiatools.com/en/tools/egfr-mdrd): Estimate glomerular filtration rate (eGFR) with the simplified 4-variable MDRD equation (2006 re-expressed, IDMS-traceable): eGFR (mL/min/1.73 m²) = 175 × SCr^−1.154 × Age^−0.203 × (0.742 if female) × (1.212 if Black). The 175 constant replaced the original 186 after IDMS-standardized creatinine calibration. The legacy race coefficient 1.212 is OFF by default (the 2021 CKD-EPI race-free equation removed it) and is provided only for historical comparison. Returns a BSA-INDEXED eGFR for CKD staging (G1–G5); for drug dosing use un-indexed CrCl (Cockcroft-Gault). Derived from Levey AS et al., Ann Intern Med 2006. Valid for stable adults, not AKI/pregnancy/extremes. Not medical advice.
