Premature infants are those born between 28 and 37 weeks of gestation. Due to the incomplete development of various organ functions, premature infants are prone to a range of complications after birth, which can be severe and may even lead to death. Generally, the survival rate of premature infants is higher if they reach at least seven months, or 28 weeks, of gestation. If premature birth is inevitable, it is recommended to seek medical care at a qualified institution with specialized neonatal resuscitation wards to enhance the chances of the infant's survival. Generally, the chances of survival significantly increase when care is received at such medical facilities.

Does a low-lying placenta cause preterm birth?

In cases of placenta previa, there is also a certain risk of preterm birth. Generally, in the late stages of pregnancy, a persistent low-lying placenta may have some impact on the development of the placenta and embryo. Excessive physical activity or normal daily activities may cause abnormal vaginal bleeding. Long-term blood clots pressing on the cervix can also promote cervical dilation and lead to preterm birth. Therefore, it is generally necessary to rest in bed and avoid excessive exercise after placenta previa occurs, in order to reduce the risk of bleeding.

Premature birth: Cesarean section or natural delivery?

Whether to opt for cesarean or vaginal delivery for preterm birth needs a comprehensive grasp of the pregnant woman's entire condition before assessing and deciding on the mode of childbirth. First, it's necessary to check if the woman has any complications and the severity of these complications, as well as whether her physical condition allows for vaginal delivery. Additionally, the changes in fetal heart rate must be considered. If the fetal heart rate is particularly poor, and the duration of vaginal delivery is long such that the child cannot endure it, then a cesarean section may be needed. Beyond these conditions, it is also important to evaluate the state of the pelvis, the size of the fetus, and the condition of the cervix. Generally, if vaginal delivery is possible for preterm births, it is still encouraged.

Does low amniotic fluid lead to preterm birth?

When there is too little amniotic fluid, it can potentially cause preterm labor. Insufficient amniotic fluid can lead to fetal hypoxia and asphyxia within the uterine cavity, and frequent fetal movements may induce uterine contractions leading to preterm labor. If reduced amniotic fluid is detected during an examination, it is important to promptly identify the cause and actively pursue treatment. Initially, drinking more water can help improve the condition, and water can also be directly injected into the amniotic cavity to improve the situation. If an examination reveals frequent fetal movements or a reduced fetal heart rate, indicating hypoxia, prompt intervention is needed, and if necessary, pregnancy termination may be considered.

Preterm labor signs

Premature birth refers to delivery between 28 to 36 weeks plus 6 days of pregnancy. Due to the lower body weight and immature organ development of the fetus, premature birth can lead to decreased survival rates and increased morbidity in newborns. The signs of impending premature birth include the following aspects: First, the occurrence of regular contractions, which are the most common sign of premature birth. If intermittent lower abdominal pain occurs, it should be taken seriously, and fetal heart rate monitoring may be necessary for assessment. Second, the appearance of blood in the vaginal discharge often indicates that the fetal presenting part is descending, which is also a sign of premature birth. Third, a physical examination may reveal shortening of the cervical canal and dilation of the cervix, suggesting the possibility of premature birth. When these conditions occur, they should be taken seriously, and medication may be necessary for treatment. (Specific medications should be used under the guidance of a physician.)

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.
