Introductiony Post maturity is when a baby has not yet been born
after 42 weeks of gestation. Post-term, post maturity,
prolonged pregnancy, and post-dates pregnancy allrefer to post mature birth.
y Post-mature births do not have any harmful effects onthe mother, but the fetus, however, can begin to suffer
from malnutrition.y After the 42nd week of gestation, the placenta, which
supplies the baby with nutrients and oxygen from themother, starts aging and will eventually fail.

Causesy The causes of post-term births is unknown. But post-
mature births are more likely when the mother has
experienced a previous post-mature birth.y Due dates are easily miscalculated when the mother is
unsure of her last menstrual period.
y When there is a miscalculation, the baby could be
delivered before or after the expected due date.y Post-mature births can also be attributed to irregular
menstrual cycles.

Causes conty When the menstrual period is irregular it is very
difficult to judge how and when the ovaries would be
available for fertilization and subsequently result inpregnancy.
y Most post-mature pregnancies are because the motheris not certain of her last period, so in reality the baby is
not technically post-mature.

Symptomsy Different babies will show different symptoms of post
maturity.
y The most commons symptoms are dry skin, overgrownnails, creases on the baby's palms and soles of theirfeet, minimal fat, a lot of hair on their head, and eithera brown, green, or yellow discoloration of their skin.
yDoctors diagnose post-mature birth based on thebaby's physical appearance and the length of themother's pregnancy.

Complicationsy Once a pregnancy has surpassed the 40 week gestation
period, doctors closely monitor the mother for signs ofplacental deterioration.
y Towards the end of pregnancy calcium is deposited onthe walls of blood vessels and proteins are depositedon the surface of the placenta, which changes theplacenta.
y This limits the blood flow through the placenta andultimately leads to placental insufficiency and thebaby is no longer properly nourished. Induced labor isstrongly encouraged if this happens.

Complications conty Post-term babies may be larger than an average baby,
thus increasing the length of labor.
y T
he labor is increased because the baby's head is toobig to pass through the mother's pelvis. This is calledcephalopelvic disproportion. Caesarean sections areencouraged if this happens.
y When post-mature babies are larger than average
forceps or vacuum delivery may be used to resolve thedifficulties at the delivery time. Difficulty in deliveringthe shoulders, shoulder dystocia, becomes anincreased risk.

Methods ofmonitoring post
mature babiesy Fetal Movement Recording
y Regular movements of the baby is the best sign
indicating that it is still in good health. The mothershould keep a "kick-chart" to record the movements ofher baby. Less than 10 movements in 12 hours is not agood sign and a doctor should be contacted. If there is areduction in the number of movements it could indicate
placental deterioration.

Methods ofmonitoring post
mature babies conty Electronic Fetal Monitoring
y Electronic fetal monitoring uses a cardiotocograph tocheck the baby's heartbeat and is typically monitoredover a 30-minute period. If the heartbeat proves to benormal the doctor will not usually suggest inducedlabor.
y Ultrasound Scany
An ultrasound scan evaluates the amount of amnioticfluid around the baby. If the placenta is deteriorating,then the amount of fluid will be low and induced laboris highly recommended.

Methods ofmonitoring post
mature babies conty Biophysical Profile
y A biophysical profile checks for the baby's heart rate,
muscle tone, movement, breathing, and the amount ofamniotic fluid surrounding the baby.
y Doppler Flow Study
y Doppler flow study is a type of ultrasound that measures
the amount of blood flowing in and out of the placenta.
