Newborn concern
A streamlined, differential-led presentation for rapid clinical review.
Twenty-second review
- Newborn illness may involve transition failure, infection, hypoglycemia, congenital disease, feeding difficulty, jaundice, or temperature instability with limited physiological reserve.
- Apnea, cyanosis, poor tone, weak feeding, temperature instability, seizure, persistent vomiting, or poor perfusion is high risk.
- Keep normal periodic breathing or caregiver uncertainty in the differential; overlapping or concurrent illness remains possible.
- For newborn concern, trends and combinations of findings are more informative than one isolated vital sign.
Compare the clinical patterns
The repeated material is grouped inside each possibility. Open only the condition you need.
SepsisTime-sensitive high-risk possibility
HPI
Clarify age in days and gestation; feeding and wet diapers; breathing, colour and tone.
Signs & symptoms
Poor feeding, cyanosis, temperature change, apnea, or lethargy.
Focused exam
Observe before touching; assess appearance, tone, interaction, work of breathing, circulation to skin, hydration, and age-appropriate neurologic response; Use weight-based and age-specific references for treatment decisions.
Brief pathophysiology
Sepsis may cause newborn concern through a time-sensitive process capable of rapid physiological deterioration.
What the trend may show
No single vital sign diagnoses sepsis. New tachypnea, abnormal temperature, tachycardia, or falling pressure—especially with altered mentation or poor perfusion—supports organ dysfunction and urgency.
Respiratory rate (breaths/min)
May rise earlyTachypnea is included in NEWS2 and can precede overt hypotension.
Temperature (°C)
High or lowAbsence of fever does not exclude sepsis; hypothermia is concerning.
Heart rate (bpm)
Often risesTachycardia is common but may be blunted by age or medication.
Blood pressure (mmHg)
May fallRelative hypotension and trend matter; profound hypotension can be late.

Respiratory failureTime-sensitive high-risk possibility
HPI
Clarify feeding and wet diapers; breathing, colour and tone; temperature.
Signs & symptoms
Poor feeding, cyanosis, temperature change, apnea, or lethargy.
Focused exam
Use weight-based and age-specific references for treatment decisions; Observe colour, tone, interaction, breathing, feeding, hydration, temperature, cord, rash or jaundice, and caregiver concerns.
Brief pathophysiology
Respiratory failure may cause newborn concern through a time-sensitive process capable of rapid physiological deterioration.
What the trend may show
Use current age-specific ranges and the child’s trend, appearance, interaction, work of breathing, and perfusion. Hypotension is a late sign of pediatric shock.
Heart rate (bpm)
Use age-adjusted rangeTachycardia may reflect fever, distress, dehydration, or compensation.

HypoglycemiaTime-sensitive high-risk possibility
HPI
Clarify breathing, colour and tone; temperature; birth and maternal history.
Signs & symptoms
Poor feeding, cyanosis, temperature change, apnea, or lethargy.
Focused exam
Use weight-based and age-specific references for treatment decisions; Observe colour, tone, interaction, breathing, feeding, hydration, temperature, cord, rash or jaundice, and caregiver concerns.
Brief pathophysiology
Hypoglycemia may cause newborn concern through a time-sensitive process capable of rapid physiological deterioration.
What the trend may show
Confirm low capillary glucose and reassess after treatment. Adrenergic signs may be absent in recurrent hypoglycemia or blunted by medications.
Blood glucose (mmol/L)
< 4.0 mmol/LBCEHS defines hypoglycemia as blood glucose below 4.0 mmol/L.
Heart rate (bpm)
May riseAdrenergic activation commonly produces tachycardia, but this is not universal.
Blood pressure (mmHg)
Often preservedBlood pressure is not a reliable discriminator; hypotension suggests another or additional process.
Temperature (°C)
May fallHypothermia can accompany prolonged or severe hypoglycemia.
