Severe hypoglycaemia

Correct low glucose promptly, protect the airway where necessary and prevent recurrence by identifying the cause.

PAUSE BEFORE USING

This is an educational summary, not a point-of-care protocol. Follow current local emergency and medicines guidance and seek senior/specialist support.

FICTIONAL SCENARIO

A fictional 70-year-old inpatient taking insulin becomes sweaty, confused and unable to swallow safely; capillary glucose is markedly low.

01 · RECOGNISE

Frame the danger first.

  • Check capillary glucose promptly in any acute change in consciousness, behaviour or neurological function.
  • Assess whether the person can swallow safely and whether intravenous access is available.
  • Consider insulin or sulfonylurea exposure, reduced intake, renal or liver impairment, sepsis, alcohol and adrenal insufficiency.
02 · FIRST PRIORITIES

Act, escalate, reassess.

  1. Call for help and protect airway, breathing and circulation while using the current JBDS/local hypoglycaemia pathway.
  2. Give route-appropriate protocol treatment promptly and recheck glucose at the specified interval.
  3. Once safe, provide longer-acting carbohydrate or ongoing glucose support as directed and continue surveillance for recurrence.
  4. Review diabetes medicines and the precipitating cause before the next dose or discharge decision.
03 · ESCALATE NOW IF

Red flags that change pace.

  • Reduced consciousness, seizure, aspiration risk or focal neurological signs that persist after correction
  • Recurrent hypoglycaemia, long-acting insulin or sulfonylurea exposure
  • Sepsis, organ failure, pregnancy or suspected deliberate overdose
04 · COMMON ERRORS

What makes care less safe.

  • Giving oral treatment to someone who cannot swallow safely
  • Correcting one reading without repeat measurement and recurrence planning
  • Restarting the same medicine regimen without explaining why hypoglycaemia occurred
