What signs indicate dehydration in pediatric patients, and how should EMS respond?

• A. Dry mucous membranes, sunken eyes/fontanelle in infants, tachycardia, cool extremities, delayed cap refill; provide oral rehydration if possible; if vomiting or unable, transport with IV access per protocol.
• B. Mucous membranes moist; tachycardia; normal cap refill; treat with fluids only if able.
• C. Dry mucous membranes but hot skin; give ice to forehead.
• D. Sunken eyes only; ignore.

Answer: (C)

In pediatric dehydration, signs reflect both fluid loss and how well the body is perfusing the tissues. Dry mucous membranes show reduced oral intake and fluid loss; a sunken fontanelle in an infant is a strong clue of significant dehydration; tachycardia is the body's early compensatory response to lower circulating volume; cool extremities and a delayed cap refill indicate reduced peripheral perfusion from decreased intravascular volume. These together help you gauge severity and urgency. The best EMS approach is to start with oral rehydration if the child can drink without vomiting, offering small sips of an age-appropriate oral rehydration solution and reassessing frequently. If vomiting prevents keeping fluids down or if there are signs of moderate to severe dehydration or shock, move toward rapid transport with access for IV or IO fluids and administer isotonic fluids per protocol. Throughout, monitor airway, breathing, and circulation, and address the underlying cause as you manage. Signs like moist mucous membranes, normal cap refill, or hot skin are not consistent with dehydration in the same way and do not guide the same urgent management. Ignoring signs like sunken eyes or fontanelles would miss key indicators of fluid loss, and relying on ineffective measures (such as giving ice or only treating with fluids if able) misses the appropriate, supportive care and rapid transport needs.
