Placental Issues and Stillbirth

The placenta plays a crucial role in pregnancy by providing the baby with oxygen and essential nutrients. Any problems with the placenta can put the baby at risk and potentially lead to stillbirth. Problems with the placenta may include poor blood flow, inflammation, and infection. Another serious condition is placental abruption, which occurs when the placenta separates from the uterine wall before birth.

Genetic and Developmental Conditions

Genetic Disorders

Genetic disorders are conditions that are present from conception. These disorders can affect the baby’s development in various ways. Genes contain the instructions for how the baby’s body grows and functions. When there are errors in these instructions, it can lead to serious health issues. Some genetic disorders are inherited from the parents, while others occur spontaneously.

Structural Abnormalities

Structural abnormalities refer to physical defects in the baby’s body. These can range from minor issues to severe malformations that can make it impossible for the baby to survive. Structural abnormalities can be caused by genetic factors, environmental influences, or a combination of both. In some cases, the exact cause remains unknown.

Fetal Growth Restriction

Fetal growth restriction (FGR) occurs when a baby does not grow at the expected rate during pregnancy. This condition can be due to various factors, including problems with the placenta, maternal health issues, or genetic conditions. Babies with FGR are at a higher risk of being stillborn. Monitoring the baby’s growth and movements can help in early detection and intervention.

Infections Leading to Stillbirth

Infections can be a significant cause of stillbirth, affecting both the mother and the baby. These infections might not always show symptoms, making them hard to detect until serious complications arise. Here are some common infections that can lead to stillbirth:

Maternal Infections

Maternal infections are those that the mother contracts and can pass to the baby. Some of these include:

• Cytomegalovirus (CMV): This is a type of herpes virus that spreads through body fluids like saliva and urine. It’s common in young children but can cause severe problems if a pregnant woman gets infected.
• Fifth Disease: Caused by parvovirus B19, this illness spreads through the air from coughs or sneezes. It’s usually mild but can be dangerous during pregnancy.
• Genital and Urinary Tract Infections: These infections affect the urinary tract and sex organs. For example, getting genital herpes for the first time during pregnancy can lead to stillbirth.
• Listeriosis: This is a type of food poisoning caused by eating contaminated food.
• Syphilis: A sexually transmitted infection that can have severe consequences if not treated.
• Toxoplasmosis: An infection from eating undercooked meat or touching cat feces.

Fetal Infections

Fetal infections occur when the baby gets infected directly. These can be caused by various pathogens, including bacteria, viruses, and parasites. Some common fetal infections include:

• Rubella (German Measles): This virus can cause severe birth defects and stillbirth if the mother gets infected during pregnancy.
• Coxsackie Virus: Known for causing hand, foot, and mouth disease, this virus can also lead to complications during pregnancy.
• Herpes Simplex: This virus causes genital herpes and cold sores. If a baby gets infected during birth, it can lead to severe complications.

Placental Infections

Placental infections are those that affect the placenta, the organ that provides nutrients and oxygen to the baby. These infections can severely impact the baby’s health and lead to stillbirth. Some examples include:

• Group B Streptococcus: This bacteria can move from the vagina to the womb, causing severe infections.
• E. Coli: A common bacteria that can cause serious infections if it reaches the womb.
• Chorioamnionitis: An infection of the placenta and the amniotic fluid surrounding the baby.

Infections are a serious concern during pregnancy and can lead to devastating outcomes like stillbirth. It’s crucial for pregnant women to receive regular prenatal care to monitor and manage any potential infections.

Malpractice

Another cause of stillbirths and birth injuries can be malpractice.

• Oxygen deprivation (asphyxia)
• Prolonged or difficult labor
• Premature birth
• Large baby size (macrosomia)
• Breech presentation
• Placental complications
• Umbilical cord problems
• Medical instrument misuse (forceps or vacuum)
• Maternal infections
• Trauma during delivery

Another cause can be injuries due to vacuum extractions. There are different types of injuries from vacuum extractors that might be the cause.

Umbilical Cord Complications

Umbilical cord complications are a significant cause of stillbirth. These issues can prevent the baby from getting enough oxygen and nutrients, which are vital for survival. Here are some common umbilical cord problems that can lead to stillbirth:

Knotted Umbilical Cord

A knotted umbilical cord can occur when the baby moves around in the womb. If the knot tightens, it can block the flow of blood and oxygen to the baby, leading to serious complications or even stillbirth.

Compressed Umbilical Cord

Compression of the umbilical cord can happen if the cord gets squeezed between the baby and the wall of the uterus. This can reduce or cut off the baby’s oxygen supply, which is critical for their development and survival.

Prolapsed Umbilical Cord

A prolapsed umbilical cord occurs when the cord slips into the birth canal ahead of the baby. This can cause the cord to become pinched during delivery, leading to a dangerous drop in oxygen levels for the baby. Immediate medical attention is required to manage this condition effectively.

Maternal Health and Stillbirth

Maternal health plays a significant role in the risk of stillbirth. Various health conditions and lifestyle factors can increase this risk. Understanding these factors can help in taking preventive measures to ensure a healthy pregnancy.

Chronic Health Conditions

Chronic health conditions such as diabetes, hypertension, and obesity are linked to a higher risk of stillbirth. These conditions can affect the placenta and the baby’s growth, leading to complications. Managing these conditions through regular medical check-ups and following a healthy lifestyle can reduce the risk.

Pregnancy-Induced Conditions

Certain conditions that develop during pregnancy, like preeclampsia and gestational diabetes, can also lead to stillbirth. Preeclampsia causes high blood pressure and can affect the blood flow to the placenta. Gestational diabetes can lead to excessive fetal growth, increasing the risk of complications during delivery.

Lifestyle Factors

Lifestyle choices such as smoking, alcohol consumption, and drug use during pregnancy can significantly increase the risk of stillbirth. These factors can affect the baby’s development and the health of the placenta. Adopting a healthy lifestyle, including a balanced diet and regular exercise, can help in reducing these risks.

Providing quality care, support, and resources that encourage healthy lifestyles and pregnancies can greatly reduce a woman’s risk of stillbirth. The annual number of stillbirths far exceeds the top five leading causes of deaths among children ages 0-14 years combined, highlighting the importance of maternal health in preventing stillbirths.

Unexplained Causes of Stillbirth

Challenges in Diagnosis

In many cases, the exact reason for a stillbirth remains unknown. This can be incredibly hard for grieving parents who want answers. Nearly 60% of all stillbirths are unexplained, meaning doctors can’t pinpoint a specific cause. This uncertainty can be very difficult to accept, but it’s important to remember that stillbirth is rarely due to anything the parents did or didn’t do.

Statistical Overview

According to one study of 1064 pregnancies, around 60% of stillbirths are unexplained. This statistic highlights the challenges in understanding and preventing these tragic events. While medical advancements have helped identify some causes, a significant number of stillbirths still leave families without answers.

Coping with Uncertainty

Dealing with the unknown can be one of the hardest parts of experiencing a stillbirth. Parents may feel a range of emotions, from sadness to frustration. It’s crucial to seek support from healthcare providers, counselors, and support groups. Remember, it’s okay to grieve and to ask for help when you need it.
