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.

Do frequent Braxton Hicks contractions lead to preterm labor?

In the late stages of pregnancy, there may be occurrences of Braxton Hicks contractions, generally happening at a low frequency of about two to three times per day. Some individuals experience these false contractions primarily at night, which disappear during the day. This is considered normal physiological behavior in the late stages of pregnancy. If there is a frequent occurrence of Braxton Hicks contractions, it may also lead to the dilation of the cervix, causing premature labor. Therefore, if this situation arises and the fetus is not yet full-term, it is recommended to go to the hospital for an examination in a timely manner, and symptomatic treatment to maintain the pregnancy may be necessary.

Signs of premature birth

Preterm birth refers to childbirth occurring between 28 and 36 weeks plus six days of pregnancy. The signs of preterm birth include the following aspects. First, regular contractions occur, generally defined as four contractions within 20 minutes or eight contractions within 60 minutes. Second, there may be a small amount of "show," mainly due to minor bleeding caused by the separation of the fetal membrane from the uterine wall. Third, many women experience a significant feeling of heaviness in the lower abdomen, which is caused by the descent of the fetal head. Fourth, upon examination, it can be found that the cervical canal has shortened and the cervical opening has dilated. When the above symptoms occur, there should be a high suspicion of the risk of preterm birth, and medications should be used promptly as an intervention to try to avoid the occurrence of preterm birth.

Is low amniotic fluid likely to lead to premature birth?

During pregnancy, if there is a reduction in amniotic fluid, it is easy for premature delivery to occur. Insufficient amniotic fluid can cause fetal hypoxia in the uterus, which may lead to frequent fetal movements and stimulate uterine contractions, resulting in premature birth. When there is a reduction in amniotic fluid, it is important to replenish it in a timely manner. This can be done by drinking more water, intravenous fluid infusion, or directly injecting saline into the amniotic cavity. To determine the best method to replenish the amniotic fluid, it is advisable to seek treatment under the guidance of a doctor and to closely monitor changes in fetal heart rate and movements.

Does placenta previa cause preterm birth?

Placenta previa is likely to lead to premature birth. Why is that? Placenta previa refers to the condition where the placenta is positioned lower in the uterus, and the most common symptom is recurrent, painless bleeding during pregnancy. This is because the low-lying placenta often leads to frequent bleeding. If the bleeding is minimal, there is still hope to maintain the pregnancy, allowing the fetus to grow longer inside the uterus. However, in the event of heavy bleeding, if the baby remains in the uterus without delivery, a critical situation can arise due to blood loss, potentially leading to the disappearance of fetal heart activity. At this point, the pregnancy would need to be terminated, thus often resulting in premature birth.

Does placenta previa cause preterm birth?

When a placenta previa occurs, it is likely to lead to premature birth. Placenta previa is a condition where, after 28 weeks of pregnancy, the placenta is positioned low in the uterus, often below the presenting part of the fetus, and attaches to the lower segment of the uterus or near the internal os of the cervix. In the late stages of pregnancy, dilation of the cervix can cause the placenta to be misaligned with the uterine wall, leading to recurrent, painless bleeding. When the bleeding reaches a certain amount, it can easily lead to premature separation of the placenta, inducing uterine contractions and the onset of premature birth. In cases of placenta previa with significant vaginal bleeding, it is necessary to terminate the pregnancy promptly.
