At 8–12 weeks of gestation, liver is a relatively bigger organ which forms 4-5-5.5% of the total body weight and protrudes through the abdominal wall. By 13 to 32 weeks of gestation, it forms 3.4% to 4.0% of the total body weight. [23] The liver weight hence forms a more or less constant proportion of the total body weight of the fetus. [24]
Fundal height can be measured from the top of the uterus to the pubic bone and indicates that the newborn is likely large in volume. Excessive amniotic fluid indicates that the fetus’ urine output is larger than expected, indicating a larger baby than normal; some symptoms of excessive amniotic fluid include shortness of breath
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] On average, babies of Asian descent weigh about 3.25 kilograms ...
It is rare for a baby weighing less than 500 g (17.6 ounces) to survive. [13] A baby's chances for survival increases 3–4% per day between 23 and 24 weeks of gestation and about 2–3% per day between 24 and 26 weeks of gestation. After 26 weeks the rate of survival increases at a much slower rate because survival is high already. [15]
After birth, health care providers will measure the baby's weight, vital signs, reflexes, head circumference, muscle tone, and posture to help determine the gestational age. [10] Various factors can influence the duration of gestation, including diseases in pregnancy and adequate prenatal care. [11]
Posture: muscle tone is reflected in the infant's preferred posture at rest. As maturation progresses, the foetus gradually assumes increasing passive flexor tone at rest that precedes in a centripetal direction with lower extremities slightly ahead of upper extremities. Term newborn (flexed posture) and preterm newborn (extended posture).
A newborn's head is very large in proportion to the body, and the cranium is enormous relative to his or her face. While the adult human skull is about one seventh of the total body length, the newborn's is about 1 ⁄ 4. Normal head circumference for a full-term infant is 33–36 cm at birth. [6]
A Cochrane review in 2017 found that there was too little evidence to show whether X-ray pelvimetry is beneficial and safe when the baby is in cephalic presentation. [ 3 ] A review in 2003 came to the conclusion that pelvimetry does not change the management of pregnant women, and recommended that all women should be allowed a trial of labor ...
