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.

How to correct the corrected age for premature babies?

Generally, as preterm infants are born several weeks early, this may lead to discrepancies in their specific months of age. If the preterm baby is developing well without other complications, it is possible to calculate the corrected age. Under normal circumstances, the simplest method to calculate the corrected age is to use the expected due date for calculation. Corrected age is calculated by taking the current age in days and subtracting the expected due date, which allows for accurately estimating the baby's current age in months. When the baby is between two and two and a half years old, you can add back the months previously subtracted, and calculate according to the normal age since, by then, the baby's developmental indicators are generally the same as those of a full-term baby.

Are the twins premature?

The likelihood of premature birth is higher in twins than in singletons, but this does not mean that all twins will be born prematurely. In the case of twins, there are two children in the uterus. Generally, the combined weight of two children is more than that of one. Additionally, there might be more amniotic fluid and a larger placental area. Therefore, the contents of the uterus occupy more volume, and when the uterus is stretched to a certain extent, its sensitivity increases. As a result, some may experience contractions and give birth prematurely before reaching 37 weeks of pregnancy.

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.

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.

How to care for premature infants

Women with premature infants should primarily focus on the following aspects: Firstly, they should ensure proper thermal protection to avoid the baby getting cold, and can use fleece hats for the baby. Secondly, attention should be given to the feeding method; premature infants should start breastfeeding as soon as possible when appropriate. If breast milk is insufficient, special formula milk for premature infants can be used. Thirdly, special attention should be given to managing the baby's breathing since premature infants might experience respiratory pauses, requiring close monitoring. Fourthly, due to the low body weight and poor immune function of premature infants, making them prone to infections, it is crucial to prevent infections and avoid cross-infection through frequent handwashing and maintaining good indoor ventilation and hygiene. Fifthly, it is important to ensure adequate supplementation of vitamins and trace elements. Sixthly, particular care should be taken with the skin and mucous membrane care, as premature infants have delicate skin and are prone to skin infections. Lastly, timely and regular vaccinations are also very important.
