Dextrose: D10 Framing
Objective: Treat symptomatic hypoglycemia with a concentration your protocol stocks — prefer titration (often D10) over a single D50 slam — and reassess glucose and mentation.
Why This Matters
D50 is hypertonic, easy to extravasate into a necrotic arm, and easy to overshoot into 400 mg/dL. Prehospital studies (including a randomized comparison and later observational D10 cohorts) found D10 corrects hypoglycemia with less post-treatment hyperglycemia and a cleaner safety story. Many U.S. systems and UK JRCALC-style guidelines now prefer 10% dextrose titrated to effect. Use what your protocol stocks — this is framing, not a formulary.
- Glucose early in AMS, seizure, stroke-like deficits
- Airway protected before any oral glucose
- IV dextrose: titrate, watch the line, recheck the number
- Glucagon if no IV and protocol includes it — still not dessert
Sequence (Education)
- Confirm hypoglycemia per your cutoff (ADA teaching often uses <70 mg/dL when symptomatic — protocol wins). See diabetic emergencies.
- If they can protect the airway and swallow: oral glucose.
- If not: IV dextrose. D10 in aliquots until they improve is the modern EMS preference. D50 still exists in some bags — if that is what you have, it is still a vesicant; use a patent, preferably large, vein and do not walk away from the line.
- No IV: IM glucagon per protocol. They still need sugar on board when they can swallow; glucagon is not a full glycogen refill in a starved alcoholic.
- Recheck glucose and mentation. Long-acting insulin and sulfonylureas bounce. Refusal rules belong to protocol and capacity, not a shrug.
Pediatrics
D50 requires error-prone dilution for kids. D10 (or D25 where stocked) avoids a tenfold math crime. Use a length-based tape and the weight-based sequence. This site does not publish mL/kg.
Field Pitfalls
- Oral paste in a patient without a gag.
- D50 through a blown hand IV.
- Leaving a sulfonylurea hypo at home because they “woke up.”
Practice
60-second drill
Partner: (1) talking, sweaty, glucose 42, gag intact; (2) seizing, no IV yet; (3) you only have D50 and a 22-gauge in the hand. Path for each.

Sources & Further Study
Named guidelines for further study. They are not clinical orders and do not replace your protocol or medical direction.
- NASEMSO National Model EMS Clinical Guidelines (2022) — U.S. EMS model language; protocol still wins
- ADA Standards of Care in Diabetes—2025 — treat symptomatic hypoglycemia; <70 mg/dL is a common teaching threshold
- Kiefer et al., Prehospital Emergency Care (2016): D10 for out-of-hospital hypoglycemia — D10 is feasible, effective, and easier to titrate than a D50 slam; less post-treatment hyperglycemia in EMS series
- Protocol owns concentration, volume, and refusal rules. This site does not publish grams.
