Newborn resuscitation

Background

Newborn Vital Signs

HR RR SBP^

>100 40-80 60-70

^<3kg (premature) SBP = 40-60

DDx

Common Newborn Problems

1. Hypoxia
   1. Primary apnea
   2. Secondary apnea
2. Hypothermia
3. Hypoglycemia
4. Meconium asp

Consider DDx (esp if older neonate)

1. Sepsis
2. Congenital Heart Dz (PGE)
3. Inborn Error of Metabolism (lactate)

Diagnosis

Assessment Triad

1. Respiration- adequacy, difficulty
2. HR >100, umbilical
3. Color

Treatment

Resucitation Inverse Pyramid

1. Dry, warm, position, suction, stimulate
   1. position: neutral (towel --> thorax)
   2. suction: oral then nasal
   3. stim: along spine or feet
   4. check glucose^
2. Oxygen (use liberally)
3. Ventilate (40-60 breaths/min @ 20-25 cmH20)
   1. BVM (indications)
      1. Apnea/gasping
      2. HR <100/min
      3. Persistent cyanosis
   2. ET^^ (indications); ETT size = Gest age (wks) / 10
      1. BVM ineffect after 30s
      2. Suction meconium**
4. Chest compressions (indications)
   1. HR <60 after above x 30 sec
      1. 120/min (resp 3:1)
      2. Stop when HR > 60
5. Medications^^^^
   1. Epi (0.01-0.03 mg/kg)
   2. D10W (4 mL/kg = 0.2gm/kg)
   3. Nalaxone (0.4 mg/kg)
      1. For opiod use <4hrs
   4. NS (10 mL/kg boluses)
   5. Dopamine gtt
      1. (5-20 mcg/kg/min)
   6. NaHCO3 - prolonged resus
      1. (1-2 meQ/kg)

^Hypoglycemia (give D10W)

• >2.5 kg = <40 mg/dL
• <2.5 kg = <30 mg/dL

^^Meconium Suctioning Indications

Meconium + -->

1. absent/depressed resp
2. poor muscle tone
3. HR <100

(2 passes w/ ET + suction)

^^^Newborn Vent Settings

Pressure Cycled: RR 30+, PIP 20/2 (Preemie 15/2)

^^^^Umbilical Vein Access

1. Cut cord 1 & 1/2 inch
2. 5F cath, 3-way stopcock
3. Feed the 'mouth'
4. Place until get blood flow (-4 cm)

Deterioration After Intubation

• D - Displacement (flexion pushes in, exten pulls it out)
• O - Obstruction of tube
• P - PTX
• E - Equipment failure

Preemie (<23-24 wks or 500 gms)

1. rapid volume may inc risk of IVH
2. usually ETT immed

Equipment

1. blankets, warmer, umbilical clamps
2. Bulb suction or wall suction
3. Catheters (5F,8F,10F)
4. Meconium aspirators
5. BVM
6. ETT 2.5-4.0 w/ stylets
7. Blades 0 & 1
8. IV catheters (22 & 24 g)
9. Umbilical caths (3.5 F & 5F)
10. syringes, 3 way stop cocks
11. Epi 1:10,000
12. Naloxone 0.4 mg/ml or 1 mg/ml
13. NaHCO3 4.2% or 8.4%
14. NS & D10W
