Newborn Assessment

Newborn Assessment: Comprehensive Notes

Newborn Vitals

  • Heart Rate:
    • Auscultate for one full minute.
    • Normal range: 120−160120-160 beats per minute (bpm).
    • Decreases during sleep.
    • Increases during crying.
  • Respirations:
    • Listen and feel for one full minute.
    • Normal range: 30−6030-60 breaths per minute.
    • Bowel sounds can sometimes complicate respiratory assessment.
  • Temperature:
    • Methods: Axillary, skin probe, rectal.
    • Normal range: 36.5−37.5extoC36.5-37.5^ ext{o}C.
  • Pain Assessment Tools:
    • NIPS (Neonatal Infant Pain Scale)
    • FLACC (Face, Legs, Activity, Cry, Consolability) scale

General Appearance

  • Head size
  • Abdomen
  • Extremities
  • Acrocyanosis (bluish discoloration of the hands and feet)
  • Melanin (skin pigmentation)

Weight & Measurements

  • Weight: Measured naked on a scale.
  • Length: Measured with the infant completely stretched out.
  • Head Circumference: Measured at the widest point on the head.
  • Initial Weight Loss: Newborns typically lose up to 10%10\% of their birth weight in the first 3−53-5 days.
  • Weight Gain: Expected to return to birth weight by 22 weeks of age.

Respiratory Assessment

  • Normal Findings:
    • Easy, unlabored breathing.
    • Absence of accessory muscle use.
    • No evidence of grunting.
    • No retractions (indentations of the skin above or between ribs).
    • No nasal flaring.
  • Abnormal Findings:
    • Grunting.
    • Retractions.
    • Tachypnea (rapid breathing).
    • Nasal flaring.
    • Long periods of apnea (cessation of breathing).
  • Periodic Breathing: Normal variation where breathing patterns fluctuate with short pauses.

Cardiac Assessment

  • Auscultation: Identify optimal locations for listening to heart sounds.
  • Rate: Assess heart rate (as per vitals).
  • Rhythm: Evaluate for regular or irregular rhythm.
  • Intensity: Note the strength of heart sounds.
  • Murmurs: Assess for the presence of any heart murmurs.

Heart Murmurs

  • Commonality: Heart murmurs are relatively common in newborns.
  • Physiologic Fetal Shunts: Often related to the closure of these shunts post-birth.
  • Sound: Typically described as a
