Newborn Infant
- Some essential systems come online, others continue to develop.
The neonatal period is about the transition from an interuterine placenta and maternally supported life to life to relatively independent life in the external environment.
In developing a broad understanding of the neonatal period you need to think about the two different environments and the effects of loss of placental support. Remember that substantial postnatal development still has to occur in many systems. Identify these systems and the associated changes that occur.
Birth
<html5media height="500" width="400">File:Birth MRI.mp4</html5media> |
The median duration of gestation for first births from assumed ovulation to delivery was 274 days (just over 39 weeks). For multiple births, the median duration of pregnancy was 269 days (38.4 weeks).
Birth Weight
The primary causes of VLBW are premature birth (born <37 weeks gestation, and often <30 weeks) and intrauterine growth restriction (IUGR), usually due to problems with placenta, maternal health, or to birth defects. Many VLBW babies with IUGR are preterm and thus are both physically small and physiologically immature. See also DOHAD.

Assisted reproductive technology in Australia and New Zealand
Assisted reproductive technology (ART) is a group of procedures that involve the in vitro (outside of body) handling of human oocytes (eggs) and sperm or embryos for the purposes of establishing a pregnancy.
Assisted Reproduction Technology (ART) is also used to identify in vitro fertilization (IVF), but now includes many new fertility techniques. Each ART treatment involves a number of stages and is generally referred to as an ART treatment cycle. The embryos transferred to a women can either originate from the cycle in which they were created (fresh cycle) or be frozen and thawed before transfer (thaw cycle).

Maternal Changes
- Puerperium - six weeks following birth, maternal reproductive organs and physiology return to pre-pregnancy state.
- Involution - process of tissue catabolism of uterus.
- Lochia - uterine (placental) discharge, blood plus mucous, continues for about 4 weeks.
- Mammary - glandular development and function.
Development does not finish at Birth
Many systems continue to grow and differentiate after birth, in particular neural, sensory, respiratory, renal, endocrine and genital.
