Unformatted text preview: COLLABORATIVE PROBLEMS of the NEWBORN Dysmaturity Syndrome ☆ Placental function deterioration in postterm pregnancies which causes interference w/oxygen & nutrient supply. This results in hypoxia & malnourishment in the fetus. ☆ Also known as postmaturity syndrome ☆ 6-12% of pregnancies go postterm ☆ postterm infants have a 2-3 x higher perinatal mortality rate than infants born at term ☆ major concern is how well placenta functions during the last wks of pregnancy ☆ Postmature Infants o Look like babies who are 1-3 weeks old o Skin is typically dry and cracked o May have long hair and nails. o May have meconium stained finger nails d/t meconium release in utero. o May weigh more than a term infant, but often appear physically wasted . They can look malnourished d/t uteroplacental insufficiency. o Lack of SQ fat due to intrauterine deprivation (poorly functioning placenta). Placenta is old, becomes calcified. o Prone to meconium aspiration syndrome: if baby gets hypoxic (from aged placenta), rectal sphincter relaxes causing meconium release. May give amnio infusion to reduce effects of meconium aspiration. o Post term infants with oligohydramnios are prone to cord compression o Prone to problems associated with their macrosomia (shoulder dystocia, prolonged birth)---------------------------------------------------------------------------------------------- Preterm Infants Account for the largest # of admissions to NICU Typically very small, minimal SQ fat (brown fat) Immaturity affects every body system More prone to ineffective thermoregulatio n: d/t minimal brown fat. Also have friable (easily broken or pulverized) capillaries. Poor muscle tone. More prone to respiratory distress : caused by insufficient production of surfactant, which is needed to keep alveoli open during exhalation. Periodic breathing with 5-10 seconds of respiratory pauses is normal. More prone to hyperbilirubinemia More prone to hypoglycemia---------------------------------------------------------------------------------------------- Kangaroo Care ☆ Method of providing skin-to-skin contact between preterm infants and their parents. Begin ASAP. Infant, wearing only a diaper and hat, is placed under the mother’s clothes between her breasts. Increases attachment. Infants better able to maintain temperature. Also, more stable heart rates and oxygen saturation levels. ☆ Found safe for stable infants, even if intubated. ☆ May breastfeed if they wish & if infant is able 1---------------------------------------------------------------------------------------------- Bilirubin Although newborn’s liver is able to conjugate bilirubin, it may not be mature enough to prevent development of jaundice during the first week of life....
