When pregnant women unload their goods and look at their newborn babies, they can't help but feel so happy. But when it was first born, it was so difficult to take care of. During the neonatal period, the various organs and other physiology of babies are different from those of adults. If one does not have a special understanding of the physiological characteristics of newborns, it is inevitable to feel nervous during the care process. What are the physiological characteristics of newborns?
What are the physiological characteristics of newborns?
1. Respiratory system: Newborns will immediately start breathing, but due to incomplete development of respiratory organs, breathing may present a faster frequency and shallower breathing depth, which is not very regular, about 40-60 breaths per minute. Premature babies may even have a pause in breathing.
2. Circulating system: Compared to the general population, newborn babies have a faster heart rate, approximately 120-160 beats per minute, and a blood pressure of approximately 6.12-10.64kPa (46-80mmHg). Some babies may also have heart murmurs.
3. Digestive system: Newborns start defecating within 12 hours after birth, and some may begin defecating during delivery. The coffee colored or dark green stool that a child initially excretes is called fetal stool. After breastfeeding, the color will change to a mixture of brown and yellow, and it will be excreted several times a day. If there is no bowel movement, bloating, or vomiting within 24 hours after birth, it is important to seek medical attention promptly.
What are the physical characteristics of newborns?
1. Skin: Newborn babies have red skin that feels cool to the touch and looks wrinkled. Some babies may have a layer of gray white fetal fat that will gradually be absorbed in the future. The soft fur grown by premature infants will disappear after one to two weeks of birth.
2. Head: The baby's head is relatively large, accounting for about a quarter of the body length, and may deform due to compression from the birth canal. Due to wet hair sticking to the scalp, the scalp may develop tumors due to partial edema, which will disappear automatically afterwards. The anterior and posterior chimneys of the head are diamond shaped and triangular in shape, with the anterior chimney closing approximately 12-18 months and the posterior chimney closing approximately 2-4 months.
3. Facial swelling: Newborns exhibit swollen facial features, thicker eyelids, shorter nasal bridges, and underdeveloped eye development, leading to physiological hyperopia and strabismus, which disappear after 2-4 weeks.
Through the above answer to 'What are the physiological characteristics of newborns?', I believe everyone should have a further understanding. For every family, after the baby is born, everyone is very happy, but there will be many difficulties in taking care of it in the future. Therefore, we must be careful and not careless in the process of taking care of the baby, otherwise your momentary negligence will bring harm to the baby.
