Different kinds of placental umbilical cords serve vital roles during pregnancy. They help in nutrient transfer and fetal development. Understanding their types contributes to better birth outcomes and prenatal care.
A normal placenta is flat and round with an average thickness or length of about 55 cm. It varies in length, about 1-4 cm wide, and connects the fetus to the placenta via the umbilical cord. A normal cord in a healthy pregnancy contains about 1-2 arterial blood vessels and 1 venous blood vessel. The vessels are protected by a gel-like substance known as Wharton's jelly. This cord allows for flexibility and support, preventing compression.
The marginal placenta umbilical cord is also called a battlement placenta. The cord in this type runs close to the edge of the placenta instead of through its center. It can complicate things if the cord gets too close to the fetus. It offers the same support as a normal cord but poses risks. They include marginal cord risks for blood vessel rupture.
With a velamentous placenta umbilical cord, the blood vessels within the cord develop outside the protective amniotic membranes. This type fails to provide adequate safeguarding for the vessels during delivery. Thus, it may lead to fragile vessels or even fetal hemorrhage. They usually connect to the placenta before spreading out and attach to the fetal membranes. It is less common. However, it has the most dangerous outcomes if not caught early.
This kind of lobe possesses one or more small accessory placentae. They are connected to the main placenta by blood vessels. These vessels may become exposed during delivery. This poses a risk of rupture and fetal bleeding. Proper lobe identification and monitoring reduce these inherent risks. It helps ensure a safe delivery while supporting the developing fetus.
Increta and percreta cords occur when the placental tissue abnormally grows into or beyond the uterine wall. An increta cord may attach to the myometrium. The percreta cord may grow through the uterine wall and into surrounding organs. It can lead to severe bleeding at delivery while still offering typical support during pregnancy. These are extremely serious conditions that require careful monitoring and medical intervention.
The placenta and umbilical cord work together to ensure that the baby grows healthy. Below are more of their features as well as their benefits during a healthy fetal development.
Placenta Features
The placenta acts as a fetus's temporary organ and source of nourishment. It is disc-shaped and about 1 inch thick, with a surface area of around 9-10 inches. The placenta has a network of blood vessels to facilitate nutrient and gas exchange. It produces important hormones that help maintain the pregnancy. These hormones include progesterone and human chorionic gonadotropin (hCG).
Umbilical Cord Features
The cord has 2 arteries that carry deoxygenated blood away from the baby and 1 vein that brings oxygenated blood from the mother. Wharton's jelly insulates and cushions the vessels to prevent entanglement or compression. The average length of a normal umbilical cord is about 55 centimeters.
Nutrient and Oxygen Exchange
The placenta acts as a filter, allowing vital nutrients and oxygen from the mother’s blood to reach the fetus. At the same time, it helps remove waste products like carbon dioxide.
Hormonal Production
The placenta produces hormones that regulate pregnancy. These hormones include progesterone and estrogen. They maintain the uterine environment and prevent maternal immune rejection of the fetus.
Protective Barrier
The placenta also offers partial immunological protection, allowing certain antibodies to pass through while shielding the fetus from harmful pathogens.
The cord connects the fetus to the placenta and facilitates transport and support. It permits fetal growth and development. Any disruptions to its structure can lead to insufficient oxygen and nutrient supply. Heavy fetuses may lead to fetal distress during labor. Understanding the types of placentas helps in identifying possible complications early. This allows for timely medical interventions and safer delivery outcomes.
Choosing cord care products or cord blood banking options depends largely on the preferences and health of the expectant mother. There are several considerations.
Healthcare professionals recommend cord blood banking as a practical way to preserve the stem cells found in the blood. Cord blood banks offer a variety of storage options. Both public and private banking contribute to the decision. Public banking allows altruistic donation for wider potential future medical use. This is usually free of charge. Private banking offers paid services to store the blood solely for the donor's family use. These banking options provide an opportunity for future stem cell therapies. They treat various diseases like leukemia and certain genetic disorders.
Delayed cord clamping is often recommended these days. Healthcare and expectant mothers invest in good cord clamping tools to help harvest blood for the baby to gain extra iron and blood cells. They reduce anemia risk. It also aids in improved fetal blood flow and oxygenation. Durable and adjustable clamps offer secure, easy-in process cord management.
Clean and safe cord care is vital to prevent infections. Neonatal care products include antiseptic wipes, natural drying powders, and biodegradable cord care sticks. They offer hygienic care while still protecting the baby. Antiseptic wipes are also great for clamping during delayed cord clamping. Parents who practice delayed cord clamping tend to lean towards biodegradable care sticks. This is because they are eco-conscious.
Expectant buyers must stock essential items before their due dates. Cord clamps, storage bags, and hygienic care tools should be on-site. This helps facilitate immediate babies’ cord blood collection and care. Also, cord blood stem cells have therapeutic potentials. They may contribute to future medical treatments for the baby or other family members in need of transplants.
Expectant buyers should only invest in tried and tested products with positive reviews. They should look out for reviews that highlight how well the products work with several cord types. Products that inspire healthy cord development and sustain safe handling will be of good use. When making purchases in bulk, buyer should inquire about samples for quality checks. Buying from reputable brands that ensure safety and efficacy gives buyers many advantages.
A healthy placenta supports the fetus throughout pregnancy. It facilitates nutrient exchange and aids in fetal development. The cord connects the fetus to the placenta. It nourishes the baby while also helping with oxygen exchange. During different situations, the cord and placenta may present different risks to the fetus.
The banking of stem cells from cord blood offers long-term potential health benefits for the baby and family members. They may be affected by genetic diseases or conditions requiring stem cell therapies in the future. Families with a history of medical issues may decide banking cord blood for stem cells be beneficial.
Delayed cord clamping transfers remaining blood from the placenta to the newborn. This boosts blood volume and iron content, which reduces infant anemia and promotes healthy growth. Pediatricians advise delayed clamping in preterm infants to help improve blood flow and prevent the risk of blood transfusion.
Clamping the cord helps manage uterine contractions. This may help reduce the risk of postpartum hemorrhage for mothers after childbirth. Expectant mothers prone to excessive bleeding during delivery may benefit from early clamping and quick uterine contraction.
Proper cord care with antiseptic wipes and natural drying powders prevents infections, sepsis, and other cord-related complications in neonates. Hospitals and home healthcare providers use these antiseptic wipes to maintain hygienic cord care daily.
The placenta can be analyzed for genetic disorders like Down syndrome or cystic fibrosis if necessary. This allows for early diagnosis and treatment or interventions for the baby. Expectant mothers and families worried about hereditary conditions usually do such analyses.
Healthcare providers focus on optimal placenta and cord handling during high-risk pregnancies, such as those involving multiple births or gestational diabetes cases. Proper care minimizes the risk of hypoxia and ensures healthy delivery. They also monitor closely for conditions like placental abruption or previa during pregnancy. This ensures timely intervention and minimizes risks to the baby and mother.
A1. These risks may include placenta previa, cord knots, or abruption. Others are stillbirth, gestational diabetes, and preeclampsia. Healthcare professionals monitor closely for signs of fetal distress or hypoxia to mitigate delivery complications.
A2. Yes, there are a couple. Delayed cord clamping allows blood to transfer from the placenta to the newborn. It boosts blood volume and iron levels, reducing anemia risk and ensuring better neonatal blood flow. This also helps in improving iron content and preventing anemia.
A3. The common practices include cleaning with sterile wipes and natural drying powders to promote healing. Parents and healthcare workers monitor the cord daily for infections and ensure proper maintenance of the hygienic environment for healing.
A4. Cord blood is rich in stem cells that can treat various diseases, such as blood disorders and genetic diseases. Families with a history of medical conditions favor cord blood banking for potential future therapies using preserved stem cells to treat the baby or a family member.
A5. Wharton's jelly insulates the cord's blood vessels during pregnancy. It ensures a smooth flow of nutrient-rich blood from the mother to the baby while protecting the vessels from compression or injury. It helps with cushioning and supporting the vessels' structure.
