Level of consciousness

✔ Changes in alertness, irritability, or lethargy are key indicators of dehydration severity.

✔A dehydrated child may become irritable early and later progress to lethargy as dehydration worsens.

✔ Assessing mental status helps determine cerebral perfusion and hydration adequacy.

✔ This is a critical early sign in infants where other clinical signs may be subtle.

✔ Monitoring LOC trends can guide timely intervention.

✔ Any altered LOC signals moderate to severe dehydration.

Blood pressure

✔ Hypotension is a late but critical sign of severe dehydration and hypovolemic shock in infants.

✔ Initially, blood pressure may remain normal due to compensatory mechanisms, but a drop indicates advanced fluid deficit.

✔ Continuous BP monitoring is important in infants with fever and tachycardia.

✔ Hypotension correlates with poor tissue perfusion and needs urgent fluid replacement.

✔ Thus, BP assessment is essential in focused dehydration assessment.

Skin color of hands and feet

✔ Pale or mottled extremities suggest peripheral vasoconstriction, an early sign of hypovolemia.

✔ Poor perfusion due to low intravascular volume can be detected by observing skin changes.

✔ Cold, pale hands and feet are early indicators before hypotension occurs.

✔ This finding is valuable in infants who cannot verbally express thirst.

✔ It provides a quick, visual clue to circulatory compromise.

Capillary refill

✔ Delayed capillary refill (>2–3 seconds) indicates poor peripheral perfusion, a reliable marker of dehydration.

✔ It helps determine circulatory status and fluid volume adequacy.

✔ Prolonged refill time correlates with moderate to severe hypovolemia.

✔ It is a quick, non-invasive bedside test in infants.

✔ Early detection allows prompt IV fluid administration if needed.

Skin turgor

✔Decreased skin turgor is a classic sign of extracellular fluid loss.

✔ In infants, turgor is best assessed on the abdomen or inner thigh rather than the hand.

✔ Poor turgor indicates moderate to severe dehydration when combined with other signs.

✔ This helps differentiate mild dehydration from more serious fluid deficits.

✔ Turgor changes are easily observed by trained nurses during the assessment.

Heart rate

✔ Tachycardia is an early compensatory response to fluid loss and hypovolemia.

✔ Infants increase their HR before BP drops, making it an early and sensitive indicator.

✔ Persistent tachycardia indicates worsening dehydration and increasing circulatory strain.

✔ Heart rate trends help guide fluid replacement therapy.

✔ It must always be interpreted alongside other dehydration signs for accuracy.
