1
Q

During passage through the birth canal, fluid is expressed out of the lungs (via the nares) and as the baby fully delivers, the lungs will with fair (rebound thoracic expansion). The temperature change from inside the mother’s body to room air stimulates the respiratory center (as may light, sounds, smells, and touch). Mild hypoxia and increasing C02 leads to acidosis which triggers the respiratory center of the medeulla oblongata in the brain

Q

Breathing is fast and shallow nitally as the alveoli expand (30-60 breaths/min) and irregular. May pause breathing for 15 secs then breathe again. Preferentially breathe through their noses and nares may need suctioning. When using bulb suction, suction the mouth first, then nares

Q

Prematurity: lack of surfacant to maintain open alveoli. Preemies often do well in the first few minutes, but then cannot maintain their airway and increased effort of respiration and can worsen quickly.
Sedative taken by mother prior to birth
Cesarean birth without labor
Fetal hypovolemia or anemai (abruption, uterine rupture, RH isoimmunization, etc)

Perinatal asphyxia (non-reassuring FHR, tight nuchal cord, cord prolapse, etc)

Q

With apnea or gasping at one minute of life, baby is taken to preheated warmer for positive pressure ventilations. With labored breathing or cyanosis at one minute, O2 sat monitoring and oxygen therapy are initiated. Supplemental oxygen can be given via face mask, endotracheal tube, oxygen hood, or nasal cannula.

Q

The first breaths dilate the pulmonary vasculature, increasing blood flow and pressure to the left atrium, resulting in the closure of the foramen ovale. (These changes happen whether you clamp the umbilical cord or not - it is the expansion of the airway, not the cord clamp, that matters) The ductus arteriosis closes more slowly, over several days or weeks.

Q

Normal rate is 110-160 (apical pulse over 1 min when at rest). Heart rate is assessed quickly at delivery (counted for 6 seconds), if under 100 at one minute of life, positive pressure ventilations and O2 saturation monitoring are initiated. If 30 secs later, its bleow 60, the baby should be intubated. Physiologic murmurs are common (no cyanosis, pallor, apnea, or feeding difficulty)

Q

Can also be dangerous. Newborns do not sweat so excessive heat can lead to seizure, brain damage, or death. A theroneutral environment is best, placing skin to skin under a blanket.
Babies needing to be unwrapped for assessment or procedures should be in a preheated radiant warmer. Normal newborn temp 97.7-99.5. Teaching: dress the infant in the same layers as an adult, protect from drafts, dry quickly after a bath

Identification: banding and footprints. Alarm system activation. Teaching parents/caregivers about safety: “back to sleep”, infants transport in crib whenever outside the room, infant must be band matched whenever taken from or returned to the room, no co-sleeping in hospital, not recommended at home. No pillows or stuffed toys in crib, not recommended at home. No pillows or stuffed toys in crib, no loose blankets. Hospital security measures to prevent abduction.

Q

Once home, baby should void at least 6 times/day, newborns fed breastmilk should stool 3 or more times per day, formula fed infants will stool less often, as little as once every 1-2 days. Keep skin clean and dry to prevent skin breakdown. Leave the umbilical cord open to air. Fold the diaper to sit below it. It will dry up and fall off like a scab in several days. infants can be tub bathed once the cord has fallen off (before then, sponge bath only)

Q

Optimal food source for babies. Exclusive for 6 months and ongoing for 12 months or more is best. Its free, requires no prep, more easily digested and enhances bonding. Reduces risk of SIDS, allergies and childhood obesity. Shows a decrease risk for ovarian and breast cancer for women who feed their babies this way. Babies should be fed q2-3 hours during the day adn at laest q4h at night initially during this type of feeding. Colostrum (early milk) contains passive immunity from lgA antibodies

A

Breastmilk

31
Q

Lactation constultants are experts in in this field and are available at most large hospitals and in the community. Le Leche League is a community based support group for this. Should be initated as soon as the newborn is stable. Stimulation of the nipples releases oxytocin and triggers the “let down” reflex that releases the milk. Women should be comfortable, have hydration available and clean hands before starting to latch the baby. Proper positioning is essential for a correct latch. Signs that a baby wants to feed include rooting, mouth to hand and sucking motions

A

Breastfeeding

32
Q

Expressed milk, donor milk, or formula can all be given via bottles. Formula fed infants may feed less frequently : every 3-4 hours at first. Hold the infant while bottle feeding, do not prop the bottle. Bottle fed infants may feed rapidly and need to burp more than breastfed babies. Pediatricians recommend vitamin D supplementation for all babies and iron supplements at 4 months for breastfed babies and solids are introduced at 6 months of age. Review importance of clean hands, careful preparation of formula and washing of supplies

A

Bottle feeding

33
Q

Blood glucose per protocol, metabolic screening and PKU genetic testing mandated in all states, serum or transcutaneous bilirubin, hearing screening, cardiac testing

A

Routine newborn testing

34
Q

Removal of the foreskin of the penis. Anesthesia is often used by more newly trained providers. Performed by either the obstetrician or the pediatrician (varies regionally). Performed second or third day of life or delayed for any medical concerns or for religious preferences. Not done with family history of Von Willebrand’s disease (infant tested first). Not done with hypospadias or epispadias (abnormal urethral location). Always done AFTER the first void to ensure normal urinary function. Assess after procedure for bleeding, swelling and ability to void, apply petroleum and gauze with diaper changes

A

Q
