Study Notes
Newborn Life Support Overview
- Most newborns are born healthy and adapt well to birth circumstances.
- Resuscitation or transitional support needs may be unpredictable at birth.
- The Newborn Life Support Algorithm is applicable from birth up to 12 hours old.
Fetal Circulation Transition
- Upon birth, key physiological changes occur:
- Fetal circulation must close rapidly.
- The umbilical cord becomes non-functional after a few minutes.
- Pulmonary circulation must initiate and open, typically occurring spontaneously.
Differences in Cardiac Arrest Causes
- In adults, cardiac arrests are the primary cause of collapse.
- In infants, respiratory arrest is most common.
Characteristics of Newborns at Birth
- Newborns are typically small, wet, and connected to the placenta.
- Their lungs contain fluid before the first breath.
Stimulation for First Breath
- Factors that can stimulate the first breath include:
- Physiological hypoxia.
- Changes in temperature.
- Physical stimulation.
Importance of Thermoregulation
- Newborns are highly susceptible to rapid heat loss, necessitating careful thermoregulation practices.
- Lower temperatures significantly increase mortality risk: a decrease of 1°C below 36.5°C correlates with a 28% rise in infant mortality.
Strategies for Optimizing Thermoregulation
- Ensure a suitable environment by eliminating drafts, closing windows, and increasing room temperature.
- At birth, effectively dry the baby, replacing wet cloths with dry ones, and provide a hat to retain body heat.
- Wrap the baby in dry towels and consider using a blizzard blanket or a transwarmer if available.
Initial Assessment During the First Minute of Life
-
Colour Assessment:
- Pink coloration indicates good perfusion.
- Blue/purple suggests a transitioning status.
- Pale skin indicates poor transition requiring immediate help.
-
Tone Assessment:
- Flexed and spontaneous movement suggests good condition.
- Floppiness indicates poor condition, necessitating prompt intervention.
-
Breathing Assessment:
- Normal respiratory rate is between 40-60 breaths per minute.
- A heart rate around 100 bpm is stable; continue monitoring thereafter.
