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 ...
Medical viability is generally considered to be between 23 and 24 weeks gestational age, meaning that these newborns have a < 50% chance of either dying or surviving with severe impairment if active care is instituted; this applies to most fetuses at ≥ 24 weeks of gestation, and to some fetuses at 23 weeks of gestation with favourable risk ...
A baby born within the normal range of weight for that gestational age is known as appropriate for gestational age (AGA). An abnormally slow growth rate results in the infant being small for gestational age, while an abnormally large growth rate results in the infant being large for gestational age.
Baby weighed as appropriate for gestational age. Birth weight is the body weight of a baby at their birth. [1] The average birth weight in babies of European and African descent is 3.5 kilograms (7.7 lb), with the normative range between 2.5 and 4.0 kilograms (5.5 and 8.8 lb). [2]
Newborns transitioning into extrauterine life will undergo periods of reactivity. These periods are divided into three stages. The first stage occurs in the first 30 minutes of life; during this stage the infant is alert and responsive with heart rate peaking at 160-180 beats per minute and then stabilizes to a baseline rate of 100-120 beats ...
Newborns typically lose 7–10% of their birth weight in the first few days, but they usually regain it within two weeks. [17] During the first month, infants grow about 1 to 1.5 inches (2.5 to 3.8 cm) and gain weight at a rate of about 1 ounce (28 g) per day. [17] Resting heart rate is generally between 70 and 190 beats per minute. [18]
From 24 to 34 weeks of gestation, when the fetus is typically viable, blood can be taken from the cord in order to test for abnormalities (particularly for hereditary conditions). This diagnostic genetic test procedure is known as percutaneous umbilical cord blood sampling. [35]
[24] [25] [26] Recent research has even shown this ability in newborns only a few hours old. [27] However, other studies have shown similar results received by Michotte (1976) in infants as young as 6 months, but not younger. [28] [29] These studies support a more developmental progression of abilities required for the perception of causality.
