Hypothermia in Newborn :
Grading based on Core Temperature (i.e temperature of Middle ear or Oesophagus)
Normal Core body temp. - 36.5 - 37.5 degree C
Rectal Temperature is close to it.
36 - 36.5 -- Cold Stress (Abdomen warm , Soles Cold ) -- Do Kangaroo Mother Tech.
32 - 36 ---- Moderate Hypothermia
< 32 ------- Severe Hypothermia
In Hypothermia < 36 - Admit NICU
Normal Baby - Abdomen Warm , Sole Warm and Pink.
All Newborns have NON-Shivering Thermogenesis -- Brown fat
Brown Fat - ( Fatty Acid Oxidation - Generate heat - distributed by Blood Vessels)
- Nape of Neck
- InterScapular area
- Around Kidneys and adrenals
Q. Mechanism of Heat transfer in Over head Radiant Warmer ?
