    Bilirubin Levels & Jaundice

    Jaundice is caused by an elevated level of bilirubin in the blood. Bilirubin is a yellow pigment produced when red blood cells break down. Indirect bilirubin is the unconjugated form that's harmful to the brain. Direct bilirubin is the conjugated form, which the liver processes and eliminates from the body.

    Study Notes

    Neonatal Assessment and Care (Part 2)

    • Nursing care and assessments:
      • Immediately after delivery (delivery ward)
      • Subsequent assessment (postnatal ward)
    • Major neonatal adaptations:
      • Physiological adaptations
      • Neurological/behavioural adaptations
    • Neonatal nutrition, screening and others:
      • Nutritional needs
      • Neonatal screening
      • Neonatal jaundice

    Learning Outcomes

    • Students will be able to outline the physiological and behavioral adaptations of newborns during transition from intrauterine to extrauterine life.
    • Students will understand the mechanism of thermoregulation in newborns, and its impacts in hypothermia or hyperthermia.
    • Students will be able to assess a neonate from head-to-toes, understanding the process and rationale behind it.
    • Students will recognize newborn reflexes and identify differential abnormal responses.
    • Students will be able to explain nutritional needs of a neonate.
    • Students will be able to describe the immunization program and neonatal screening in Hong Kong.
    • Students will be able to identify cases and describe the management of neonatal jaundice
    • Students will describe care of neonates at health risk (e.g., infection) and manage risks.

    Timing and Types of Newborn Assessments

    • Immediately after birth:
      • Need for resuscitation (using Apgar Scoring at 1 and 5 minutes)
      • If stable, place with parents for early attachment/bonding
    • Within 1 to 4 hours after birth:
      • Progress of newborn adaptations to extra-uterine life
      • Determination of gestational age
      • Ongoing assessment for high-risk problems
    • Within first 24 hours, or before discharge:
      • Complete physical examination according to the protocol
      • Nutritional status and feeding abilities (breast, bottle, or cup feeding)
      • Behavioral state organization abilities

    Apgar Scoring System

    • A rapid standardized assessment to determine if the newborn is at risk/requires resuscitation.
    • Assigned at 1 minute and 5 minutes of life, for all infants.
    • Reflects cardiorespiratory and neurological status.
    • Scored between 0 and 2 in 5 different categories.
    • Score of <7 at 5 minutes requires further assessments until the score reaches ≥7.
    • A 5-minute score of 0-3 is associated with increased mortality for both preterm and full-term infants.

    Immediate Physical Assessment After Birth

    • Apgar Scoring System (1952,1958): a rapid assessment of a newborn's condition, considering five criteria (appearance, pulse, grimace, activity, respiration) at 1 and 5 minutes after birth; scoring system used to rapidly assess a newborn's physiological status; can identify those who require additional care.
    • Score between 0-2 for each criterion.
    • Values below 7 warrant additional assessments every 5 minutes until score is over 7, or baby is over 20 minutes of age.

    Other Observations

    • Airway: patency of each naris
    • Chest wall: movement – pattern of respiration
    • Abdomen: soft, non-distended, umbilical stump
    • Skin: acrocyanosis vs. central cyanosis
    • Genitalia: evaluated before determining baby’s gender.
    • General: check for birth-related injuries (nerve injuries, fractures).

    Immediate Nursing Care at Birth (Part 1)

    • Maintain airway and respiration, including tactile stimulation, gentle oral suction (only if needed)
    • Umbilical cord clamping (1-3 minutes after birth).
    • Prevent hypothermia by pre-warming and wrapping with a warm towel
    • Support skin-to-skin contact.

    Immediate Nursing Care at Birth (Part 2)

    • Medications:
      • Vitamin K1 (1mg IM): to prevent Vitamin K deficiency bleeding.
      • IMI: 0.5 mg for infants ≤1.5 kg, 1mg for > 1.5 kg (within first hour).
      • Oral vit K1 (2mg P.O): for infants who cannot receive IMI (given within 1 week, 4 week, 8 weeks).

    Immediate Nursing Care at Birth (Part 3)

    • Promote bonding:
      • Skin-to-skin contact with mothers after delivery and encourage skin-to-skin contact to help with postpartum bonding.
      • Postpartum Skin-to-Skin Contact (SSC) can be initiated during the surgical stages, recovery room, and within the first hour to support breastfeeding, if not contraindicated.

    Subsequent Assessment (Nursery/Postnatal Ward)

    • Objectives of complete newborn assessments:
      • Check for danger signs and normal adaptations after birth.
      • Assess congenital malformations and traumas
      • Assess growth and development & manage related factors.
      • Provide appropriate care and treatment.
      • Provide advice and counselling to the mother and family.
    • Assessments to be conducted in a warm room (>25°C) avoiding 15-20 min. time limits/excessively naked newborns.
    • A doctor review within 24 hours.

    Assessments of the Newborn

    • Vital signs
      • Pulse (110-160 bpm, 80-100 bpm for deep sleep, >180 bpm when crying)
      • Respiration (30-60/min)
      • Blood pressure: assessed based on facility policy, and varies based on gestational age and birth weight
      • Temperature (rectal 37-38 °C /axillary 36.5-37.5°C)

    Characteristics of a Healthy Newborn at Birth

    • Respiratory rate (RR): 30-60 breaths/min
    • Heart rate: over 100 bpm
    • Color: mostly pink
    • Body Temperature: 36.5°C-37.5°C
    • Posture: arms and legs flexed
    • Movements: active
    • Cries, reacts to light and sound
    • Moves both legs and arms equally
    • Able to suck
    • Passes urine within 24 hrs and 6+ times after day two
    • First stool (meconium): within 24 hours after birth

    Head-to-Toe Assessments of the Newborn

    • General appearance:
      • Head: proportionally large for body size, symmetrical, neck short
      • Neck: short, with the chin resting on the chest
      • Chest: round with prominent abdomen, soft
      • Hips: narrow
      • Muscles: flexed position
      • Extremities: short
      • Hands: usually clenched tight

    Newborn Measurements

    • Weight: 2.5-4 kg (between 37-41 weeks of gestational age)
    • Head circumference: 32-37 cm
    • Chest circumference: 30-35 cm
    • Length: 46-56 cm (approx. 2.5 cm growth per month).

    Physical Assessment of Newborn (Head)

    • Symmetry (large, ¼ of body size)
    • Head circumference (32–37 cm)
    • Fontanels (two soft spots; anterior fontanel – 1–4 cm; posterior<1cm).
    • Abnormalities: hydrocephalus, microcephaly, asymmetry, molding, caput succedaneum, cephalohematoma.

    Caput Succedaneum vs. Cephalohematoma

    • Caput succedaneum: collection of fluid, edematous swelling of the scalp
      • Caused by pressure from birth canal.
      • Crosses suture lines
      • Resolves within 12-48 hours
    • Cephalohematoma: collection of blood
      • Caused by pressure from birth canal or instrumental delivery.
      • Does NOT cross suture lines
      • Resolves in 2-5 weeks.

    Neurological Reflexes in Newborns (Part 1)

    • Moro (Startle) reflex:

      • On sudden head extension (or loud sound of 90 decibels), symmetrical abduction and extension followed by flexion.
      • Present at 37 weeks gestation, disappears around 4-6 months.
    • Palmar & Plantar grasp reflexes:

    • Flexion of fingers or toes when an object is placed in palm/ball of hand/foot.

    • Present at 28 weeks' gestation and disappears by 2-3 months.

    Neurological Reflexes in Newborns (Part 2)

    • Rooting reflex: stroking the baby's cheek stimulates head turning towards the stimulation. Established at 34 weeks and disappears at 4 months (when visual cues take over).
    • Sucking reflex: stimulation of palate or nipple causes sucking. Present at 34 weeks; diminishes with age.
    • Tonic neck reflex: When the head is turned to one side, the arm and leg on that extended, while the arm and leg on the other side remain flexed.

    Neurological reflexes in the newborns (Part 3)

    • Babinski Reflex: Eliciting a stroking of the sole of the foot from the heel to the toe. Toes flare outward & Big toe dorsiflexes. (Contrast to the adult response). Disappears (~3 months).
    • Stepping/Pacing reflex: when newborns are held upright, one foot then the other giving the impression they're walking; Present from 36 weeks of gestation, disappears after 3 months.

    Assessment of Maturity

    • Estimation of gestational age.
    • Neurologic and musculoskeletal development.
    • External physical characteristics.
    • Amount of breast tissue.
    • Amount of lanugo.
    • Cartilaginous development of ear.
    • Testicular/labia development.

    Assessment of Neuromuscular Maturity

    • Determine neurological function.
    • Note presence, strength, and symmetry of reflexes.
    • Assess common newborn (primitive) reflexes.

    Assessment of Scar Sign

    • No resistance, elbow moves past midline, score 1 (before 30 weeks)
    • Elbow is at midline, score 2 (36-40 weeks)
    • Elbow is not at midline, score 4 (over 40 weeks).

    Additional Notes

    • Combining the physical assessment score and neuromuscular scores estimates gestational age.
    • Scores vary greatly based on maturity from low (less than 26 weeks of gestation) to high (mature or postmature).
    • For very low birth weight preterm infants (< 1500 gms), the scores may not be as accurate.
