The terms of stillbirth, death of the baby in the womb, death
of the baby (fetus) in the womb, loss of the baby in the womb or intrauterine
ex fetus (mort fetus) are the same terms. If the baby is alive at the time of
birth and dies after birth, it is a different situation and is not included in
this group.
Stillbirth is a term used for babies who die in the womb
after the 20th week of pregnancy, and it works about 200 pregnancies. If fetus
death occurs in the womb of the mother before the 20th pregnancy week, it is
not called stillbirth or infant death in the womb, it is called miscarriage. If
death is named according to the baby's weight, deaths over 500 grams are called
stillbirths, while those below 500 grams are called miscarriage.
More than 3 million stillbirths occur every year in the
world.
Causes of
stillbirth:
- Pregnancy (perinatal) infections (Rubella, CMV, Toxo etc.)
- Preeclampsia and blood pressure are applied
- Bleeding due to pregnancy (placenta previa)
- Detachment placenta (separation of the baby's partner)
- Diabetes
- Mother's injury, accident, trauma
- Sepsis
- Twin to twin transfusion syndrome
- Cord accidents, cord compression or knotting
- Uterine anomalies (congenital abnormalities of the uterus)
- Blood incompatibility (Rh incompatibility)
- Hydropes fetalis (immune or non-immune)
- Cord sagging
- Problems with birth
- Congenital anomalies in the baby (such as congenital heart
diseases)
- Chromosomal (genetic) anomalies in the baby
- Developmental retardation
- Premature birth and early arrival of waters
- Apart from these, there may be stillbirths due to other
reasons and for no reason.
Undisclosed
stillbirths: Situations in which there is no reason to explain the death
of the baby who died in the womb. The cause of nearly 20% of all stillbirths
cannot be found. There is no mother-related illness or infant-related anomaly
or other condition to explain stillbirth.
Risk
factors for stillbirth (intrauterine dead fetus):
There is a higher risk of stillbirths in pregnancies with the
following conditions.
- Maternal age (more than 35) or too young (adolescent
pregnancy)
- Multiple Compartments
- Overweight of the mother (obesity)
- Twin and triplet (multiple) pregnancies
- Smoking of the mother
- Having had a still birth, a bad esthetic story
- Having high blood pressure, diabetes, goiter, kidney
diseases, SLE and other systemic diseases in the mother
- Mother having thrombophilia
- Pregnancy cholestasis
- Thrombophilia
- IUGR, oligohydramnios, polyhydramnios
- Assisted reproductive techniques (ART)
- Overdue pregnancy
- Mother's drug use
It is aimed to deliver the baby immediately with normal birth
or cesarean delivery. Prolonged stay of the deceased baby in the womb may cause
certain substances (thromboplastin) to pass into the mother's blood and cause
bleeding-clotting disorder (DIC-Disseminated intravascular coagulation) in the
mother.
As explained above, death in the womb before 20th week is not
classified as stillbirth and these are included in the miscarriage group.
Therefore, in this case, the inside of the uterus is evacuated through
abortion.
