Preterm delivery
What are the signs of premature birth?
Preterm birth refers to delivery occurring between the 28th and 36th week +6 days of pregnancy. Firstly, it is advised to prioritize prevention and identify the symptoms of preterm labor as early as possible to allow for early treatment. Signs of preterm labor include the following aspects: First, the occurrence of regular contractions, such as 4 contractions within 20 minutes or 8 contractions within 60 minutes, with each contraction lasting more than a minute; second, the appearance of a small amount of bloody show, which is a sign of imminent labor; third, many times pregnant women will experience a significant feeling of heaviness. Upon examination, cervical dilation and a shortening of the cervical canal may be found. When these symptoms appear, it is important to rest in bed promptly and undergo treatment with medications.
Premature birth refers to childbirth happening before the normal completion of pregnancy, specifically before 37 weeks of gestation.
Premature birth, as the name implies, occurs when labor happens too early. Premature birth is generally defined by gestational age, specifically when delivery occurs between 28 and 36 weeks and 6 days of pregnancy. In contrast, miscarriage refers to delivery before 28 weeks; full-term birth refers to delivery between 37 and 41 weeks and 6 days; and post-term birth refers to delivery after 42 weeks of pregnancy. Premature birth can be quite harmful to the fetus, as during this period the fetus is smaller in size and less mature. If premature birth occurs, the survival rate of the fetus is relatively low. Causes of premature birth in clinical practice include vaginal inflammation, premature rupture of membranes, twin pregnancy, and shortened cervical canal. Therefore, prevention of premature birth should target these underlying causes.
Is it normal for a premature baby to weigh more than five jin?
If the newborn is currently premature and weighs a bit over five jin (approximately 2.5 kilograms), it is generally considered within the normal range. Typically, if a newborn weighs more than 2500 grams, it is considered a full-term birth weight and there are no abnormalities. Therefore, if the newborn's weight is within the normal range after birth and there are no abnormalities in the development of the organs, it is possible to observe temporarily without the need for an incubator. It is also crucial to closely monitor the various vital signs of the newborn and pay attention to normal feeding and care.
What are the symptoms of preterm labor?
According to the current situation, generally, embryos delivered between 28 to 37 weeks of cessation of menstruation are considered preterm. Under normal circumstances, if there is already regular abdominal pain accompanied by abdominal bloating and uterine contractions, it is generally considered whether there is a possibility of threatened miscarriage. Normally, frequent uterine contractions and abdominal hardening can stimulate cervical dilation, which generally may lead to preterm birth. Therefore, these are the signs of preterm labor. If regular abdominal pain occurs and persists for several hours without relief, it is advisable to seek medical attention promptly for treatment to prevent premature birth.
What are the signs of premature birth?
Under normal circumstances, during preterm labor, there may first be regular uterine contractions accompanied by continuous cervical dilation. This situation should be considered a possible onset of preterm labor. Generally, the period from after 28 weeks to before 37 weeks of gestation is considered the possible range for preterm labor to occur. Therefore, if there are symptoms like regular abdominal pain, backache, or a feeling of heaviness, it is necessary to seek medical attention promptly. When needed, local physical therapy, symptomatic treatment, or administration of medications to sustain the pregnancy can effectively alleviate the symptoms.
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.
Premature birth is how many weeks?
Premature birth refers to childbirth occurring before full-term pregnancy. In contrast, the terms miscarriage, full-term birth, and post-term birth are used, differentiated mainly by the gestational weeks. Miscarriage refers to the expulsion of a fetus before 28 weeks of pregnancy, premature birth refers to expulsion between 28 and 36 weeks plus 6 days, full-term birth refers to expulsion between 37 and 41 weeks plus 6 days, and post-term birth refers to expulsion after 42 weeks of pregnancy. The definition of premature birth being set between 28 and 36 weeks plus 6 days mainly stems from the fact that during this time period, the fetus already has a significant chance of survival. However, the overall survival rate is lower than that of a full-term birth. It is crucial to promptly treat the newborn in cases of premature birth, while also preventing complications in the mother.
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.
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.
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.
