Preterm delivery
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.
Can oxytocin be used for premature birth?
Under normal circumstances, babies born between 28 and 37 weeks of gestation are referred to as premature infants. Persistent and regular abdominal pain, accompanied by dilation of the cervix, usually suggests preterm labor and a likely onset of labor, necessitating timely medical attention for appropriate examination and treatment. Normally, during the process of preterm labor, if there is insufficient uterine contraction or other abnormal conditions, it might be appropriate to use oxytocin to induce labor. If the mother has no other complications, vaginal delivery is still the primary method of delivery to reduce conditions such as fetal hypoxia in the uterus.
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.
Does premature birth affect intelligence?
Premature birth generally does not affect a baby's intellectual development, as the brain is mostly well-developed by the time of premature birth, and intelligence is not greatly affected. With appropriate nutrition post-birth, the intelligence of premature babies can generally recover to that of average children. However, if the baby experiences intrauterine hypoxia during premature birth, this can affect the brain cells and may even lead to cerebral palsy. Therefore, it is important to closely monitor the baby's diet and neurological responsiveness if premature birth occurs. If there are concerns, a hospital check-up can be conducted to promptly identify any issues with the child.
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.
Do contractions easily lead to premature birth?
There are two types of contractions. The first type is false labor contractions, which occur in the late stages of pregnancy. They generally happen more in the evening or afternoon and disappear in the morning. The true labor contractions are regular and intensify in waves, accompanied by an increase in vaginal discharge or spotting. If it's false labor, rest can usually improve the condition, and it's not a concern. However, some people, due to extreme anxiety, may experience frequent false labor contractions. In such cases, our general approach is still to recommend treatment for pregnancy maintenance. If it's true labor, there is definitely a possibility of premature birth.
What are the causes of premature birth?
Preterm birth refers to delivery between 28 and 36+6 weeks of pregnancy. Due to the lighter weight and lower maturity of the fetus at this stage, the survival rate of newborns is often reduced. The causes of preterm birth include the following aspects: First, the presence of vaginal inflammation can easily lead to premature rupture of membranes, which in turn triggers contractions and can lead to preterm labor. Second, in twin or multiple pregnancies, the increased irritability of the uterine wall can easily cause spontaneous contractions, which in turn lead to preterm labor. Third, an excess of amniotic fluid can increase the pressure inside the amniotic cavity, easily stimulating spontaneous uterine contractions or premature rupture of membranes. Additionally, if the cervical canal is congenitally short, or if there has been previous cervical surgery, this can also easily lead to preterm labor.
What is the earliest month that premature birth can occur?
Under normal circumstances, the entire childbirth process for a fetus is divided into three stages: early pregnancy, middle pregnancy, and late pregnancy. Generally, fetal development between 28 to 40 weeks is considered a viable period. During this time, if delivery occurs, the baby's chances of survival are very high. However, normally, a fetus between 37 to 40 weeks is considered full-term, so babies born before 37 weeks are referred to as premature. Premature babies need close monitoring of their developmental status after a normal delivery to avoid potential complications.
Signs of premature birth
Generally, babies born between 28 and 37 weeks of gestation are considered premature. Normally, premature babies have underdeveloped organ systems, which makes them prone to serious abnormalities in various organs after birth. This can lead to conditions such as respiratory distress syndrome or cerebral palsy. Signs of premature labor typically include sudden regular abdominal pain without any other abnormalities, accompanied by clear uterine contractions and a feeling of abdominal heaviness, with a persistent, notable dilation of the cervix.
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.)
