First, let's discuss the concept of preterm birth, which is defined as births occurring between less than 37 weeks and more than 28 weeks of gestation. There are many reasons for preterm birth, such as genetic factors, premature rupture of membranes, or complications during pregnancy. If the pelvic size is adequate and the child can tolerate delivery, then vaginal delivery is preferred; however, if the fetus is too small or there are complications during pregnancy such as gestational hypertension, gestational diabetes, or if the mother's health status is not good, it is recommended to opt for a cesarean section to ensure a timely delivery.

Will early engagement of the fetus lead to premature birth?

Fetal engagement refers to the leading part of the fetus having entered into the woman's pelvis. There isn't a necessary correlation between fetal engagement and preterm birth; however, fetal engagement could indicate a possibility of preterm birth or an upcoming labor. It is important to pay attention to the timing of fetal engagement and the expectant mother's sensations post-engagement. Firstly, for the vast majority of pregnant women, fetal engagement should occur after week 32 or 34. Early engagement should prompt attention to the presence of other clinical symptoms. Secondly, be mindful if there are feelings of descent or abdominal pain after the fetal engagement. Regular checks of the cervical canal length should be conducted if these sensations frequently occur. If the cervical canal is progressively shortening, it may suggest a risk of preterm birth. If there is no shortening of the cervical canal, it means that the fetal engagement and these clinical symptoms are unlikely to cause preterm birth.

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.

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.

Is prematurity prone to jaundice?

Premature infants often exhibit jaundice. This is because during premature birth, the baby's gas distension function is not yet perfect, the liver's detoxification capabilities are relatively weak, and the ability to process bilirubin is poor. Therefore, jaundice easily occurs, and the physiological jaundice in premature infants is more severe compared to full-term infants. Due to the reduced sucking ability and swallowing reflex in premature infants and their underdeveloped intestinal function, most babies cannot be normally breastfed after birth. The increased absorption of bilirubin in the intestines exacerbates the jaundice in premature infants. It is advised for premature infants to initiate breastfeeding as soon as possible and some medications can also be used to promote liver enzyme activity.

Is excessive amniotic fluid likely to cause premature birth?

Polyhydramnios is relatively common during pregnancy and can have a certain impact on the fetus. There are many reasons that can cause polyhydramnios, but regardless of the cause, polyhydramnios tends to lead to preterm birth. When there is an excessive amount of amniotic fluid, it puts significant pressure on the amniotic sac, which can easily lead to premature rupture of membranes. Premature rupture of membranes itself can stimulate the cervix, release inflammatory mediators, thereby causing contractions and symptoms of preterm labor. After the membranes rupture prematurely, infection within the uterine cavity is likely to occur, generally meaning that the possibility of keeping the pregnancy going for a long duration is unlikely. Therefore, polyhydramnios is associated with a higher risk of preterm labor. In clinical practice, if excessive amniotic fluid is detected during prenatal check-ups, it is advised to control the diet, engage in appropriate physical activities, or use other methods to keep the amniotic fluid level within the normal range.
