Study Notes
Newborn Characteristics
- Newborn period is the first four weeks of life. It's a transition from intrauterine to extrauterine life.
- Newborn care involves assisting the infant adapt to the external environment and promote well-being.
- Respiratory rate is 30-60 breaths per minute, diaphragmatic breathing, shallow and irregular, and periodic breathing (intermittent apnea) during sleep.
- Heart rate is rapid, 120-160 beats/minute. Blood pressure (BP) ranges from 80/50 mmHg in the first 10 days.
- Peripheral circulation is sluggish, potentially leading to mild cyanosis of hands and feet.
- Normal temperature is 36-37°C. Healthy, clothed term babies regulate temperature effectively. Hyperthermia can occur from heat sources. Infants are vulnerable to hypothermia if exposed to cold or lacking proper nutrition.
- Gastrointestinal system: The mouth's mucous membrane is pink and moist. Stomach capacity is small (15-30ml). Normal gastric emptying time is 2-3 hours. Meconium is present in the large intestine from 16 weeks gestation, passed within 24-72 hours. Stool transitions in color (brownish-yellow) from the 3rd to 5th day, and the infant typically passes 8-10 stools daily or less frequently.
- Immunological adaptation: Newborns possess some immunoglobulin at birth. Breast milk, particularly colostrum, provides passive immunity during the first few months. levels of immunoglobulin M (IgM) at term are 20% of adult levels.
- Vision: Visual structures are present and functional at birth, responsive to bright light.
- Hearing: Newborns turn towards sounds and prefer their mothers' voices.
- Smell/Taste: Infants prefer their mother's milk smell and can differentiate various smells within a few days.
- Touch: Newborns are highly sensitive to touch and enjoy skin-to-skin contact. The grasp reflex enhances bonding.
Assessment of Newborn
-
Anthropometric measurements:
- Head circumference: 33-37 cm
- Chest circumference: 30-33 cm
- Weight: 2.5-3.5 kg
- Length: 45-55 cm
- Posture: Flexion of head and extremities, resting on chest and abdomen.
-
Apgar score: assesses respiration, reflexes, irritability, pulse, heart rate, skin color, and muscle tone at 1 and 5 minutes.
- Scores: 7-10 (normal), 4-6 (mild asphyxia), 0-3 (severe asphyxia)
- Skin: Smooth, flexible, good skin turgor. Covered with vernix caseosa, lanugo hair, Mongolian spots, and milia.
- Eyes: Edematous eyelids, reactive pupils, absence of tears, blinking reflex.
- Ears: Flexible pinna, at the top of the pinna, on the horizontal line with outer canthus of eye.
- Nose: Patent, thin, white discharge.
- Mouth and throat: Intact, high arched palate, minimal salivation, gag, sucking and rooting reflexes.
- Neck: Short, thick, surrounded by skin folds.
- Abdomen: Protuberant contour, soft, three umbilical cord vessels.
- Genitals: Male: smooth glans, penis meatus centered. Female: swollen genitals.
- Extremities: Symmetrical, free movement.
- Back: Observe spinal symmetry. Check the anus for patency, and meconium presence.
Conditions of Newborn Head
- Caput succedaneum: Scalp edema resulting from birth labor pressure.
- Cephalhematoma: Hemorrhage under the periosteum of the cranial bones, from birth trauma.
- Differences between caput succedaneum and cephalhematoma:
- Appearance: Caput succedaneum appears at birth, with no increase in size. Cephalhematoma appears hours after birth, with size increase for 2-3 cm.
- Disappearance: Caput succedaneum disappears in several days after birth. Cephalhematoma disappears 6 weeks after birth.
- Borders: Caput succedaneum has a vague, poorly defined border, while cephalhematoma has a marked, well-defined border.
- Cause: Caput succedaneum due to edema. Cephalhematoma due to subperiosteal hemorrhage.
- Complications: Caput succedaneum rarely causes complications. Cephalhematoma may cause complications such as Jaundice, intracranial hemorrhage, or shock.
Neurological Assessment
- Reflexes: Include rooting, sucking, grasp (hand and feet), Moro reflex, startle, and stepping reflexes.
Immediate and Postnatal Care
- ABCW principle: Airway, Breathing, Circulation, and Warmth are prioritized during delivery to ensure adequate infant resuscitation.
- Airway: Holding the infant upside down temporarily to clear the airway, followed by gentle suction for breathing establishment and improved skin color.
- ABGAR score: Evaluate the infant's vital signs and response after birth, at 1 and 5 minutes to assess for normal response, mild asphyxia, or severe asphyxia.
- Warmth: Maintaining infant warmth is essential immediately after birth because rapid heat loss occurs through evaporation; dry the baby with a warm towel and keep the room warm.
- Umbilical Cord: Double ligation at 5cm from the umbilicus and 2 cm further to prevent strangulation. 3-5cm umbilical clamp placement. Removal of excess umbilical cord.
- Weight and Measurements: Weigh, measure length, and circumference (head and chest) of the newborn.
- Identification: Identifying the infant by sex and mother's name, using band/bracelet around wrist/ankle or foot print for identification.

- Breastfeeding initiation
