Q

Reasons for neonatal insensible water lose (IWL)

A
  • Lower gestation - high BSA, and immature water permeable skin
  • skin defects
  • high body/ambient temp
  • radiant warmer
  • heat emitting phototherapy

Q

Decreasing insensible water lose in neonates

A
  • double walled incubator or plastic heat shield
  • increased ambient humidity
  • plastic bag
  • humidification of inspirated gas in CPAP or ventilator
  • antenatal corticosteroids promote maturation of skin and kidneys

Q

Neonatal hypoglycaemia defined as

A

<2.6 during the first 48 hours of life

17
Q

Treatment for symptomatic hypoglycaemia in neonates

A
  1. D10W at 2ml/kg followed by 4ml/kg/hr infusion. target BGL >2.6mmol/L
18
Q

Treatment of BGL in neonates >1.8 but <2.6

A

feed at 8ml/kg q2 hours

19
Q

Three medications that might be used in NICU for neonatal hypoglycaemia

A
  1. glucagon
  2. diaxozide
  3. octerotide
20
Q

Treatment for BGL <1.8 with or without symptoms

A

IV dextrose 2ml/kg bolus followed by infusion 4ml/kg/hr

21
Q

When should neonates achieve a new set point for glucose

A

72-96 hours of life

3-4 days

22
Q

RF for neonatal hypoglycaemia

A
  1. excessive insulin production (LGA, IDM)
  2. Low glycogen reserve (IUGR, SGA)
  3. Increased demand (critically ill)
  4. Maternal conditions (DM, preeclampsia, maternal BB use)
  5. newborn errors of metabolism, hepatic dysfunction
23
Q

Glucose checks and timing in HIE

A
  • measure glucose every 20-30 minutes after birth
  • measure glucose every 30-60 minutes after correction

neonatal hypoglycaemia was detected in 16% of newborns with HIE

24
Q

when does the 421 rule start

A

28days - 17 years

25
Q

rule of 50 for D50

A

give 1cc/kg

50x1=50

26
Q

rule of 50 for D25

A

Give 2cc/kg (25x2=50)

27
Q

Rule of 50 for D10W

A

5cc/kg

10x5=50

28
Q

rule of 50 for D5

A

Give 10cc/kg

5 x 10=50

29
Q

glucose triangle

A
top = want (ie, 15)
left = have (d10)
right = need (d50)

calculate the differences then add those two volumes to the same syringe. kids are annoying

30
Q

cross multiple to change dextrose concentration.

Example: d10 at TFI 140ml/kg/day to d15

A
  1. TFI with D10=140ml/kg/d
  2. multiple (d)10x140 = 1400
  3. divide 1400/15 = 93.3
  4. TFI with D15 = 93.3ml/kg/d
