Adaptation to extrauterine life. At the end of pregnancy, the fetus must take the journey of childbirth to leave the reproductive mother. Upon its entry to the air-breathing world, the newborn must begin to adjust to life outside the uterus. This is true for all viviparous animals; this article discusses humans as the most-researched example ...
Neonate- small for gestational age, inadequate feeding, respiratory distress. Neonatal hypoglycemia, also called low blood sugar in newborn babies, occurs when an infant's blood glucose level is less than what is considered normal. [1] There is inconsistency internationally for diagnostic thresholds. In the US, hypoglycemia is when the blood ...
Small for gestational age (SGA) newborns are those who are smaller in size than normal for the gestational age. SGA is most commonly defined as a weight below the 10th percentile for the gestational age. [1] SGA predicts susceptibility to hypoglycemia, hypothermia, and polycythemia. [2] By definition, at least 10% of all newborns will be ...
Placental insufficiency or utero-placental insufficiency is the failure of the placenta to deliver sufficient nutrients to the fetus during pregnancy, and is often a result of insufficient blood flow to the placenta. The term is also sometimes used to designate late decelerations of fetal heart rate as measured by cardiotocography or an NST ...
Thermoregulation. Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
Intrauterine growth restriction (IUGR), or fetal growth restriction, is the poor growth of a fetus while in the womb during pregnancy. IUGR is defined by clinical features of malnutrition and evidence of reduced growth regardless of an infant's birth weight percentile. [5] The causes of IUGR are broad and may involve maternal, fetal, or ...
Skin-to-skin contact with the mother can help with thermoregulation. Low birth weight babies often spend time in a temperature-controlled incubator due to their inability to maintain core body temperature. LBW newborns are at increased risk of hypothermia due to decreased brown fat stores. Plastic wraps, heated pads, and skin-to-skin contact ...
Brazelton Neonatal Assessment Scale. The Neonatal Behavioral Assessment Scale (NBAS), also known as the Brazelton Neonatal Assessment Scale (BNAS), [1] was developed in 1973 by T. Berry Brazelton and his colleagues. [2] This test purports to provide an index of a newborn's abilities, and is usually given to an infant somewhere between the age ...
