Climate change, heat and child health — branching viva

Opening (2 minutes)

Examiner: "This athlete is confused after collapsing in the heat. What is your working diagnosis and first priority?" [6] [7]

Strong answer: Exertional heat stroke until proven otherwise — heat stress plus CNS dysfunction. Cool immediately, ideally with cold-water immersion, while supporting ABC and arranging hospital care. Sweating does not exclude the diagnosis. [6] [7]

Branch A — Field algorithm

Examiner: "Walk me through your field steps in order." [7]

Strong answer: Scene safety; remove from heat; strip gear; start immersion cooling if available; airway protection if needed; glucose; IV access; fluids for hypovolaemia; seizure control; continuous monitoring; transport with ongoing cooling if still critically hot; do not delay cooling for imaging. [7] [6]

Branch B — Prevention and acclimatisation

Examiner: "How should the club prevent the next case?" [5]

Strong answer: Progressive heat acclimatisation over about 10–14 days; hydration access; modified work-to-rest with humidity/heat; shade; event cancellation policies; written emergency action plan that includes immersion. [5]

Branch C — Climate and equity

Examiner: "In clinic, parents ask if climate change is really a children's health issue." [3] [12]

Strong answer: Yes — more extreme heat and other pathways (air quality, infections, food/housing stress) harm children, especially those with less cooling and more disadvantage. Give practical heat-wave plans and acknowledge advocacy/system roles. [3] [12]

Branch D — Vehicle and infants

Examiner: "What do you tell every family about cars?" [5]

Strong answer: Never leave a child in a parked vehicle. Cabin heat rises quickly; young children cannot self-rescue and can develop classic heat stroke. [5]

Close

Examiner: "One-line summary?" [3] [7]

Strong answer: "Cool heat stroke first, prevent the next case with acclimatisation and never-leave-in-car rules, and treat climate heat as core paediatric equity work." [3] [7]
