4 Nov 2007ACoRN © Alerting Signs

5 Nov 2007ACoRN © Hypothermia All newborns are at risk for temperature instabilityAll newborns are at risk for temperature instability Babies at increased risk for hypothermia include:Babies at increased risk for hypothermia include: –unwell –preterm, especially LBW (<2000g) and VLBW (<1500g) –SGA –open lesions –ambient temperature is < 23 o C or air drafts exist –being cared for by us!

6 Nov 2007ACoRN © Hypothermia Cold stress can cause: irritable (initially) / lethargicirritable (initially) / lethargic pale, mottledpale, mottled metabolic acidosismetabolic acidosis hypoglycemia / hyperglycemiahypoglycemia / hyperglycemia respiratory distress, apnea, tachypnearespiratory distress, apnea, tachypnea bradycardia / tachycardiabradycardia / tachycardia vasoconstriction, hypoxia, shockvasoconstriction, hypoxia, shock

7 Nov 2007ACoRN © Hyperthermia Causes include:Causes include: –iatrogenic –maternal epidural –maternal hyperthermia –infection –CNS disorders –administration of PgE 1 Babies with intrapartum or neonatal hyperthermia are at increased risk of neurodevelopmental complicationsBabies with intrapartum or neonatal hyperthermia are at increased risk of neurodevelopmental complications
