Management of Pediatric Cardiac Arrest Due to Hypoglycemia

Check blood glucose concentration during resuscitation and treat hypoglycemia promptly with dextrose if documented, as hypoglycemia combined with hypoxia and ischemia is harmful and associated with higher mortality. 1

Immediate Recognition and Treatment Algorithm

During Active Cardiac Arrest

  • Identify hypoglycemia as a reversible cause ("H's and T's") during the resuscitation effort 1
  • Check point-of-care glucose immediately during the cardiac arrest resuscitation (Class I recommendation) 1
  • Administer dextrose promptly if hypoglycemia is documented, as this addresses a potentially reversible cause of arrest 1, 2

Standard PALS Protocol Continues Simultaneously

While addressing hypoglycemia, maintain high-quality CPR:

  • Push hard and fast: Compress at least 100/min to a depth of at least 1/3 anterior-posterior diameter of chest 1
  • Minimize interruptions in chest compressions 1
  • Establish vascular access: IO access is rapid, safe, and effective as initial vascular access in cardiac arrest (Class I recommendation) 1
  • Administer epinephrine: 0.01 mg/kg (0.1 mL/kg of 1:10,000 solution) IV/IO every 3-5 minutes during ongoing resuscitation 1
  • Compression-ventilation ratio: 15:2 without advanced airway; continuous compressions with 8-10 breaths/min once advanced airway placed 1

Critical Nuances About Hypoglycemia in Cardiac Arrest

Evidence Supporting Treatment

Animal studies demonstrate that hypoglycemia combined with hypoxia and ischemia is particularly harmful and associated with higher mortality compared to either condition alone 1. This provides biological plausibility for treating documented hypoglycemia during arrest.

A case report documented rapid return of spontaneous circulation (ROSC) after dextrose administration in hypoglycemic cardiac arrest 2, though this represents low-level evidence.

Evidence Questioning Routine Treatment

Important caveat: A large EMS study of 33,851 out-of-hospital cardiac arrests found that among hypoglycemic patients (7% of arrests), survival to hospital discharge with good neurologic outcome did not differ between treated and untreated groups (6% vs 8%, p=0.1) 3. Only 0.08% of all patients with documented hypoglycemia received field treatment and survived with good neurologic outcome 3.

Clinical Decision Point

Despite the equivocal outcome data, the guideline recommendation remains clear: check glucose and treat if low (Class I) 1. The rationale is that:

  • Hypoglycemia is easily correctable
  • Animal data shows harm from combined hypoglycemia-hypoxia-ischemia 1
  • Individual cases demonstrate benefit 2
  • The intervention carries minimal risk when hypoglycemia is documented

Post-ROSC Glucose Management

Avoid Both Extremes

After achieving ROSC:

  • Monitor blood glucose levels continuously and avoid both hypoglycemia and sustained hyperglycemia 1
  • Do not use "tight" glucose control: Multiple studies show increased mortality with tight glucose control in critically ill children and adults 1
  • Avoid hypoglycemia aggressively: Significant rates of iatrogenic hypoglycemia occur with tight glucose control protocols 1

Evidence Base for Post-ROSC Management

There is insufficient evidence to recommend specific glucose targets in children with ROSC following cardiac arrest 1. Animal studies show both prolonged hyperglycemia and hypoglycemia after resuscitation worsen brain injury 1.

If treating hyperglycemia post-ROSC, monitor glucose concentrations carefully to prevent iatrogenic hypoglycemia 1.

Common Pitfalls to Avoid

  • Do not delay CPR to check glucose: Check glucose during ongoing resuscitation, not before starting compressions 1
  • Do not give dextrose routinely without documented hypoglycemia: Routine dextrose administration in cardiac arrest without confirmed hypoglycemia is associated with increased mortality and worse neurologic outcomes 2
  • Do not confuse calcium administration indications: Calcium is NOT indicated for routine pediatric cardiac arrest; only give for documented hypocalcemia, hyperkalemia, hypermagnesemia, or calcium channel blocker toxicity (Class III: Harm for routine use) 1, 4
  • Do not implement tight glucose control post-arrest: This increases hypoglycemia risk without proven benefit 1
