Preterm delivery
What is the earliest gestational week that a premature baby can survive?
Preterm infants, how many weeks can survive, first let's talk about the concept of preterm birth. The concept of preterm birth is more than 28 weeks but less than 37 weeks, this is called premature birth. However, with the improvement of neonatal resuscitation technology, in China, if it’s after 26 weeks, the vast majority of newborns can also survive. But after survival, the cost is quite high. For instance, if it's in a top-tier hospital, the cost for newborns born between 26 and 28 weeks can be around several hundred thousand yuan. So, even after some medical insurance policy reimbursements, you would still have to spend around tens of thousands of yuan on your own.
Premature birth is how many weeks?
Under normal circumstances, embryos that develop from 28 to 40 weeks are considered viable, and babies born during this period generally have a good survival ability. However, babies born before 37 weeks of amenorrhea are generally considered premature. Therefore, babies born between 28 weeks and 36 weeks plus 6 days are considered premature. Premature babies, due to the immaturity of their organs and systems, are prone to complications. If the baby has already been born, it is recommended to actively pursue appropriate premature care and symptomatic treatment.
Is premature birth prone to cerebral palsy?
Under normal circumstances, not all preterm infants will develop cerebral palsy. Preterm babies are more susceptible due to their immature organ systems compared to full-term babies. If they face poor adaptation to the environment during or after childbirth, it can increase the likelihood of developing cerebral palsy. However, this does not mean that cerebral palsy will occur in all cases. Furthermore, since the brain development system is not fully mature in preterm infants, conditions such as brain hypoxia may occur, which can affect the brain and contribute to the development of cerebral palsy.
Is premature birth hereditary?
Premature birth is not hereditary. There are many causes of premature birth, including reasons associated with the pregnant woman herself, such as hypertension and diabetes during pregnancy, as well as concurrent conditions like chronic nephritis and hyperthyroidism, which can lead to premature birth. Additionally, premature birth can be caused by a relaxed cervix, poor uterine development, congenital uterine malformations, and uterine fibroids. Furthermore, trauma to the abdomen during pregnancy, long-distance and prolonged travel, fatigue, and excessive emotional fluctuations can also lead to premature birth. Therefore, these factors related to premature birth are not associated with genetics.
Premature birth is how many months?
Preterm birth refers to a newborn born between 28 and less than 38 weeks of pregnancy. Moreover, at this time, the heart size is generally more than 1000 grams. There are many reasons for this occurrence, most of which are related to intrauterine infection in pregnant women, such as patients with premature rupture of membranes or chorioamnionitis are prone to preterm birth. Additionally, if there has been a previous pregnancy, abortion, with a short interval between them, or if an ultrasound detects that the cervical length is less than 25 millimeters, there is also an increased likelihood of preterm birth.
How to switch from preterm formula to regular formula?
Generally, in the early stages of preterm infants, it is still necessary to feed them promptly with preterm formula. Since the gastrointestinal function of preterm infants is relatively weak, they may not be able to digest and absorb some full-term formula, which can easily increase the burden on the gastrointestinal tract. If the baby's development is currently good, you can switch to ordinary formula. During the transition between two formula brands, there should first be a gradual shift; you can start by mixing the two formulas, using more preterm formula and less ordinary formula. Gradually switch to the new ordinary formula brand, reducing the amount of preterm formula, allowing the baby to adapt gradually.
Can premature birth be natural delivery?
Whether a vaginal delivery is possible in the case of preterm labor depends on the condition of the pregnant woman and the fetus, including the woman's birth canal, labor strength, the size and position of the fetus, among other factors. Generally, during a medical visit, a doctor will measure the woman's pelvis to roughly determine whether vaginal delivery is feasible. Women who experience preterm labor should go to the hospital for timely medical care and choose a hospital equipped for emergency services. If preterm delivery occurs, the baby's respiratory function may be relatively weak, necessitating the use of special equipment to assist breathing.
Causes of Premature Birth
Generally, there are many reasons that can cause symptoms of preterm birth. Normally, due to reasons such as cervical dilation, or the occurrence of regular abdominal pain, preterm labor may be induced. In some cases, long-term vaginal inflammatory conditions can lead to premature rupture of membranes, or cervical canal dilation may also cause preterm birth. If symptoms of preterm birth occur at present, it is necessary to actively suppress contractions, protect the fetus, and provide symptomatic treatment. If this is ineffective, it is advisable to actively prepare for rescuing and caring for the newborn.
Is a posterior placenta more likely to lead to premature birth?
The placenta is divided into anterior and posterior walls, with the posterior wall being a normal location for the placenta, which is unrelated [to preterm birth]. Generally, there is a hereditary tendency for preterm birth, and it is more likely to occur in individuals with certain physical constitutions or in cases of twin pregnancies. Additionally, people with gestational diabetes are also prone to preterm birth. Therefore, the posterior wall of the placenta has no correlation with preterm birth. Conditions like placenta previa or premature placental detachment are placental positions that can lead to preterm birth issues, and some people may experience preterm birth under these circumstances.
Does premature birth hypoxia affect intelligence?
Under normal circumstances, if a preterm infant suffers from hypoxia, severe cases may have an impact on future intelligence. However, if preterm infants experience hypoxia after childbirth, they generally receive oxygen therapy, which also affects their intelligence to some extent. Therefore, in daily life, it is still necessary to strengthen the care of preterm infants, adjust their diet, and after oxygenation, appropriately supplement DHA and other substances that can promote brain development and effectively improve issues such as delayed brain development in infants and toddlers.
