Pediatric heat illness / hypothermia

10-second priorities

ALS
Start here
Choose cooling for heat illness or warming for hypothermia.
Do not miss
No unsafe oral intake; hypothermic bradycardia has a separate pathway.
Next decision
Severe heat: early base contact. Apparent cold arrest: pulse check 30–45 seconds.

Priority checkpoints. Full criteria, doses and exceptions below.

Separate cooling from warming pathways and recognize when altered mental status or arrest changes the response.

FIELD REFERENCE

Full criteria & treatment guidance

Key cautions & base contact

  • Keep hypothermic bradycardia distinct from the ordinary pediatric bradycardia algorithm.
  • Severe heat illness requires prompt cooling and transport; do not wait for a precise temperature to recognize the listed clinical triggers.

Mild or moderate heat illness

  • Move to shade or a cooler area with airflow. Use a fan when available and passive cooling such as cool wet towels or cold packs as tolerated.
  • Encourage water or a balanced, non-caffeinated salt drink only when oral intake can be safely tolerated. Reassess mental status and perfusion for progression.

Severe hyperthermia

  • Confusion or unconsciousness, hot dry skin, or hypotension activates the severe pathway. Contact base early for destination, with a pediatric-capable base preferred. Provide high-flow oxygen.
  • For hypotension or poor perfusion, saline is 20 mL/kg IV/IO, maximum 250 mL, with base contact; may repeat twice for three total boluses.
  • Use available active and passive cooling, including cold packs at the axillae, posterior neck, and groin with airflow. All pediatric hyperthermia patients require ALS escort.

Hypothermia with a pulse

  • Remove wet clothing, conserve heat, and begin available warming. Monitor and document the rhythm.
  • Expect a slow rate and weak pulse; SO-P-105 directs against trying to reverse hypothermic bradycardia in the field. Transport immediately to the nearest ERC.

Apparent arrest

  • Check for a pulse for 30–45 seconds before starting CPR. If arrested, use the pediatric arrest pathway; assist ventilation without hyperventilating and continue warming.
  • Do not pronounce in the field under this pathway. Contact base and provide ALS transport to the nearest appropriate ERC. Report exposure, warming/cooling measures, perfusion, rhythm, and fluids.

  • Hypothermic apparent arrest

    Check for a pulse for 30–45 seconds before starting CPR. If arrested, use the pediatric arrest pathway; assist ventilation without hyperventilating and continue warming.

  • Keep hypothermic bradycardia distinct from the ordinary pediatric bradycardia algorithm.

UNDERSTAND THE CARE

Why the thermal context must remain explicit

Heat and cold exposure share the need for repeated assessment but lead to opposite environmental interventions. Record the exposure, clothing, intake and changes in consciousness and perfusion. Severe heat findings require prompt action even before a precise temperature is available.

Applying the guidance

For cold exposure, conserve heat and follow the deliberate pulse assessment if arrest is uncertain. Do not merge ordinary pediatric bradycardia treatment into the hypothermic-with-pulse branch. During transport, describe the warming or cooling already applied and the response, including fluids and rhythm changes.

Putting it together

Teaching example: a cold child has a very slow pulse. Communicate the cold-exposure context and use the thermal order, rather than applying the routine bradycardia pathway solely because of the rate.

About OCMedic · Editorial approach & corrections

A sweaty child can still have severe heat illness

Sweating does not exclude heat stroke. CDC/NIOSH includes profuse sweating as well as hot dry skin among possible findings. In a heat-exposed child, altered consciousness or poor perfusion should not be downgraded because the skin is wet.

Describe the change from the child’s normal interaction and the response to cooling. Continue the pediatric severe-heat pathway and its base-contact instructions when those clinical triggers apply.

Background: CDC/NIOSH heat-related illnesses; pediatric care remains governed by SO-P-105.

Base-contact conditions

Conditional requirement: Required as soon as possible for severe hyperthermia destination, with hypotension/poor-perfusion fluid treatment, and apparent hypothermic cardiac arrest. CCERC pediatric base is preferred. This is not a blanket rule for mild heat illness or every hypothermic child.
