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 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 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 swollen feet during pregnancy lead to premature birth?

Swelling of the feet is a common clinical symptom after pregnancy, but generally, foot swelling is not directly related to preterm birth. However, sometimes, if pathological factors cause foot swelling, it may lead to preterm birth. The most common cause of foot swelling during pregnancy is the increased size of the uterus compressing the veins and arteries in the pelvis, causing obstruction of venous return, which leads to swelling of the feet. However, this is a physiological change and does not cause preterm birth. Pathological factors, such as hypertension during pregnancy or renal diseases during pregnancy, might cause generalized edema. If the condition is severe, medical intervention for medically induced preterm birth may be required. However, it is the primary disease that causes preterm birth, not the swelling of the feet.

Premature birth is how many weeks?

Under normal circumstances, embryos that develop from 28 to 40 weeks are considered viable, and babies born during this period generally have a good survival ability. However, babies born before 37 weeks of amenorrhea are generally considered premature. Therefore, babies born between 28 weeks and 36 weeks plus 6 days are considered premature. Premature babies, due to the immaturity of their organs and systems, are prone to complications. If the baby has already been born, it is recommended to actively pursue appropriate premature care and symptomatic treatment.

Preterm birth refers to how many weeks?

Premature birth refers to a baby born after the pregnancy has reached 28 weeks but before completing 37 weeks. Most of these babies weigh less than 2500 grams at birth and have poorer adaptive abilities compared to full-term babies. They require special care. Feeding premature infants can be challenging. They generally need to be fed breast milk or formula every two to four hours. Start by feeding once or twice; if there is no vomiting for six to eight hours, continue feeding some milk. Also, position the baby's head to one side to prevent inhalation of vomit.
