Study Notes
Apgar Scoring
- A quick system review of newborn systems at 1 and 5 minutes post-birth
- Determines extrauterine adaptation, guiding interventions
- Scores range 0-3 (severe distress), 4-6 (moderate difficulty), 7-10 (minimal/no difficulty)
- Five criteria: heart rate, respiratory rate, muscle tone, reflex irritability, and color
- Each criterion rated 0-2, with a total score indicating newborn condition
- Example: heart rate 120, good cry, pink skin, would score 10
- Consider genetic background for accurate color assessment
Newborn Assessment Overview
- Understanding newborn physiologic response to birth essential for nursing care
- Key elements include Apgar score, physical exam, Ballard Score, vital signs, and complications
- Transition to extrauterine life requires respiratory and circulatory system adjustments
- Respiratory function establishment marked by first breath and umbilical cord clamping
- Circulatory adaptation involves closure of ductus arteriosus, ductus venosus, and foramen ovale
- Immediate post-birth assessment critical to identify abnormalities or complications
Equipment for Newborn Assessment
- Bulb syringe for suctioning mucus
- Pediatric stethoscope for heart rate, breath sounds, bowel sounds
- Axillary thermometer for monitoring temperature
- Blood pressure cuff for measuring blood pressure
- Scale for weighing newborns
- Tape measure for length (crown-to-heel) and head circumference
Initial Assessment Procedures
- Quick initial assessment for critical abnormalities
- Skin color, peeling, birthmarks, nasal patency observation
- Chest assessment: breathing, heart and lung sounds auscultation
- Abdominal assessment: umbilical cord, abdomen inspection
- Neurologic assessment: muscle tone, reflexes, fontanel size evaluation
- Document gross structural malformations
Expected Reference Ranges
- Weight: 2,500 to 4,000 grams (5.5 to 8.8 lbs)
- Length: 45 to 55 cm (18 to 22 in)
- Head Circumference: 32 to 36.8 cm (12.6 to 14.5 in)
- Chest Circumference: 30 to 33 cm (12 to 13 in)
Gestational Age Assessment
- Performed within first 48 hours after birth
- Crucial for predicting neonatal morbidity and mortality
- Physical measurements and New Ballard Score used
New Ballard Score
- Assesses neuromuscular and physical maturity
- Each parameter (e.g., neuromuscular, physical) rated -1 to 5
- Total score indicates gestational age in weeks
- Score of 35 indicates approx. 38 weeks gestation
- Helps identify preterm and post-term infants
Classification of Newborns
- Classified by gestational age and birth weight
- Appropriate for Gestational Age (AGA): 10th-90th percentile birth weight
- Small for Gestational Age (SGA): Below 10th percentile birth weight
- Large for Gestational Age (LGA): Above 90th percentile birth weight
Normal Deviations in Skin
- Milia: Small pearly spots on face, usually vanish on their own
- Mongolian Spots: Blue-gray or brown pigmentation, common in darker-skinned infants, typically harmless
- Telangiectatic Nevi (Nevus Flammeus): Flat pink/red marks, typically on the neck or face, usually fade with age
- Capillary Flammeus: Pink marks that do not blanch, often seen on the face, and are permanent unless treated
Vital Signs Assessment
- Sequence: respirations, heart rate, blood pressure, temperature
- Normal respiratory rate: 30-60 breaths/min
- Normal heart rate: 110-160 beats/min
- Normal temperature: 36.5°C to 37.5°C (97.7°F to 99.5°F)
- Abnormal findings like crackles, wheezing, grunting, or nasal flaring indicate respiratory distress
Physical Examination from Head to Toe
- Newborn posture typically curled up with moderate flexion.
- Skin color transitions from deep red to purple (acrocyanosis), especially in first few hours
- Jaundice may appear by day 3 due to increased bilirubin levels (usually resolves spontaneously)
Head Assessment
- Head circumference should be 2-3 cm larger than chest circumference
- Head circumference greater than or equal to 4cm larger than chest circumference may indicate hydrocephalus
- Regular monitoring crucial for neurological development
Caput Succedaneum and Cephalohematoma
- Caput Succedaneum: Localized soft tissue swelling due to birth pressure, resolves in 3-4 days without treatment
- Cephalohematoma: Blood collection between periosteum and skull bone, does not cross suture lines, resolves in 2-8 weeks
Sensory Assessment
- Eye Examination: Symmetry in size, shape, distance between inner/outer canthus, assess for tears, pupillary and red reflexes
- Ear and Nose Assessment: Ear positioning, nasal patency, possible abnormalities
- Oral and Neck Assessment: Palate closure, symmetry, tongue protrusions, presence of neck webbing
Reflexes and Neurological Assessment
- Sucking/Rooting, Palmar/Plantar grasp, Moro, Symmetrical Tonic Neck, Babinski, Stepping reflexes documented
- All reflexes should be present at birth unless there is a developmental delay
Extremities Assessment
- Assessing for full range of motion, symmetrical extremities, evaluating bowed legs, flat feet, and pink nail beds. Absence of extra digits noted
Pain Assessment in Newborns
- CRIES scale and NIPS used to assess pain.
- Behavioral changes like alterations in sleep, feeding, or activity are noted indicators.
- Physiological responses (e.g., increased heart rate, shallow respirations) also evaluated for pain.
Newborn Laboratory Values
- Hgb: 14-24 g/dL
- Platelets: 150,000-300,000/mm³
- Hct: 44-64%
- Glucose: >40-45 mg/dL
- Other laboratory (RBC count, bilirubin) values based on time after birth
