Study Notes
Newborn Life Support
- Newborn life support aims to help babies transition successfully from fetal to extrauterine life.
- The algorithm applies to babies from birth to 12 hours old.
- Most babies adapt well at birth, but the need for resuscitation is often unpredictable.
Fetal Circulation & Transition at Birth
- At birth, fetal circulation rapidly shuts down.
- The umbilical cord becomes redundant after a few minutes.
- Pulmonary circulation opens as the baby breathes.
- This transition typically happens spontaneously.
Respiratory Arrest in Babies
- While adults collapse due to cardiac arrests, babies commonly experience respiratory arrests at birth.
- This is because newborns are small, wet, attached to the placenta, and have fluid-filled lungs.
Stimulating the First Breath
- Hypoxia, temperature change, and physical stimulation can trigger a baby's first breath.
- The lungs transition from being full of fluid to full of air within 0.6 seconds.
Thermoregulation
- Thermoregulation plays a crucial role in newborn survival, as babies are highly susceptible to heat loss.
- For every 1 degree Celsius below 36.5 degrees, the risk of infant mortality increases by 28%.
- Optimizing thermoregulation should not delay essential care.
Strategies for Maintaining Newborn Temperature
- Create a warm environment: minimize drafts, close windows, turn off fans, increase heating.
- Dry the baby immediately after birth, replacing wet towels with dry ones.
- Cover the baby with a hat and dry towels.
- Use a blizzard blanket and a transwarmer if available.
Initial Assessment
- Immediately assess the baby's color, tone, and breathing within the first minute of life.
- Color: Pink (well-perfused), Blue/purple (transitioning/moderate), or Pale (not transitioning, requires assistance).
- Tone: Flexed, spontaneous movement (good condition) or Floppy (poor condition, needs immediate intervention).
- Breathing: 40-60 breaths per minute (good condition) or 100 bpm (good, continue observing).
