Newborn-specific physiological phenomena

Newborn-specific physiological phenomena

Galactorrhea: The newborn’s stomach is horizontal, with a small stomach capacity. The sphincter muscles at the entrance of the stomach are loose, but the pyloric muscles at the exit are relatively tight.Cardiac, return to the esophagus, overflow into the mouth, and flow out of the small mouth.

In addition, the neuroregulatory function of the digestive tract of the newborn is not yet perfect, which is also the cause of milk reflux.

Physiological galactorrhea does not require treatment. As long as you pay attention to care, you generally increase the age of the month and will slowly recover until it disappears.

  Epithelial beads, horse teeth, and mantis mouths: Some newborns have hard white palate on their mouths, and some white beads are visible, which are medically called epithelial beads.

Epithelial beads are caused by incomplete cell shedding, which has no effect on the baby, and will disappear on its own after a few days without treatment.

There may also be white beads on the tooth ulcers of newborns, which look like teeth that have just emerged, and some are like small teeth in the mouth of a pony. This phenomenon is commonly known as “horse teeth”.

A small pile of aunt pads, commonly known as “mantis mouths”, will accumulate on the two toes of the newborn’s mouth.

Like epithelial beads, horse teeth and mantis mouths do not need to be treated, they will disappear on their own.

  Enlarged breasts and sunken nipples: unless born to a baby or a baby, born 3?
After 5 days, the physiological phenomenon of breast swelling will appear.

There are broad beans or hawthorn-sized indurations on the touch. Squeeze gently to get milk.

Newborn breast enlargement is the result of maternal estrogen’s effect during hypertension, which is usually 2?
Can subside within 3 weeks.

Neonatal breast cancer is swollen. Do not squeeze it. If you accidentally squeeze the nipple, it will bring in bacteria, cause redness, swelling and inflammation of the breast, and may even cause sepsis.

If it is a baby girl, squeezing will cause inflammation of the mammary glands, secreting part of the mammary glands, and it will affect milk secretion in adulthood.

  Jaundice: Also called physiological jaundice of the newborn.

Neonatal jaundice may occur 72 hours after birth.

This is due to the specificity of neonatal bilirubin metabolism, which is a normal physiological phenomenon.

The serum bilirubin of term infants generally does not exceed 12 mg / dl, and temporary jaundice occurs about a week after birth, which occurs about 50%.

Serum bilirubin in premature infants generally does not exceed 15 mg / dl, and the incidence of temporary jaundice is about 80%.
Subsides naturally after 10 days.

  Physiological weight loss (collazon): The physiological weight loss of newborns is a common phenomenon in newborns.

In the first few days after birth, newborns have long sleep, weak sucking power, low feeding time and frequency, a lot of water evaporated from the lungs and skin, and a relatively large amount of fecal excretion. In addition, the mother’s milk secretion is small at the beginningTherefore, in the first few days of birth, the newborn’s weight does not increase, but instead falls. It is a normal physiological phenomenon. It is commonly known as “collapse”, and novice mothers need not worry.

In the following days, the weight of the newborn will increase rapidly.

  Physiological peeling: About two weeks after the birth of the newborn, peeling occurs.

Good baby, the tender skin starts to explode overnight, and then it starts peeling. The beautiful baby seems to be coated with a layer of paste and cracked.

This is the metabolism of newborn skin, the replacement of old epithelial cells, and the generation of new epithelial cells.

Fetal fat that is attached to the newborn’s skin at birth is replaced by metastatic epithelial cells, which results in the phenomenon of physiological peeling of the newborn and does not require treatment.

  Physiological alopecia: Some newborns have hair loss within a few weeks after birth. Most of them are hidden hair loss, that is, thick and shiny hair that gradually becomes thin, pale, and thin; very few are sudden hair loss.Hair loss occurred almost overnight.

Neonatal physiological hair loss, most will gradually recover, it is normal, mothers should not worry.

At present, there is no clear explanation for the physiological alopecia of newborns.

  Crying normally: The language of a newborn is crying. The meaning is roughly: “Mom, listen, how healthy I am!

“Medicine calls this kind of cry as a sports cry. The cry sounds frustrated, not harsh, the sound is loud, the rhythm is strong, and there is often no tears to replace.
5 times, each time shortened, extended up to 2 hours, without accompanying symptoms, does not affect diet, sleep, play normally.

If the mother touches the baby lightly, the baby will smile; if you place the baby’s small hand on its belly and shake it twice, the baby will be quiet.

When your baby is crying like this, it is better for the mother not to interrupt the baby and let the baby “speak” with you for a while, this is a good parent-child communication.

  Laugh: Newborn laughs often appear in sleep, smile slightly, or just tilt the corners of their mouths upwards.

When a newborn is awake, it is not easy to laugh or to laugh.
It is natural for a newborn to laugh.

When the newborn’s body is in the best condition, there are more laughs; when the newborn is uncomfortable, there are fewer laughs, even frowning, and crying and groaning when it is severe.

Newborns have their own emotions, sorrows and sorrows, and mothers can make preliminary judgments on their health through their expressions.

  Neonatal Pioneer Head (Tumor): Newborn babies born through the birth canal have headaches that are squeezed by the external force of the birth canal, causing scalp edema, blood stasis, congestion, partial overlapping of the skull, high and pointed head, like a “pioneer”Doctors call it “Pioneer Head”, also called neoplasia.
Newborns born by caesarean section have a round head and no obvious deformation, so there is no vanguard head.

Tumor formation is a normal physiological phenomenon and will gradually change over a few days after birth.

  Fast and slow breathing: newborns have a small chest cavity and a small amount of gas exchange, which is mainly due to the increase in the number of breaths to maintain gas exchange.

Normal newborn breathing rate is 40?
50 times.

The development of the newborn’s central nervous system is immature, and the breathing rhythm is sometimes irregular. Especially in sleep, there will be uneven breathing speed and breath hold. These are normal.

  Retina: Newborns will have sharp jaws or limbs. Novice mothers often think that this is “convulsions” and make a big problem.

Neonatal neurodevelopment is not yet complete, and it is easy to make generalized responses to external stimuli.

When a newborn hears an external sound, it is often the whole body up and down, with limbs stretched out into a hug, which is a generalized response to the stimulus.

Newborns also lack directional ability to stimulate and cannot distinguish the source of the stimulation.

Mothers can try it and touch any part of the baby lightly. The baby’s response is almost the same-the limbs are stretched out and they quickly flex to the body.

The mandible is also a manifestation of the generalized reaction, not smoking, and the mother need not be nervous.

  Facial expressions are weird: newborns will have some strange expressions that are difficult for mothers to understand, such as frowning, grinning, empty sucking, pouting, nose bending, etc. Novice moms have no experience and will think this is a “problem” for the baby.It is the normal expression of the newborn and has nothing to do with the disease.

When the baby repeatedly appears an expression, it is necessary to see the doctor in time to rule out the possibility of convulsions.

  Struggle: Novice mothers often ask the doctor that the baby is always hard, especially when he wakes up, sometimes his face flushes with red, isn’t it uncomfortable for the baby?

The baby is not uncomfortable. Instead, he is comfortable.

Newborns are blushing, that is stretching lazy waists, a kind of exercise that moves the muscles and bones, and the mother should not be surprised.

It is not necessary to hold your baby tightly, not to force the baby hard, or take the baby to the hospital.

  Frightened: The development of the newborn’s nervous system is not yet complete, and the neural tube has not been completely wrapped. When there is an external stimulus, the newborn will suddenly startle or cry.

In order to prevent the baby from being “frightened”, the mothers often wrapped the newborn’s limbs to sleep more peacefully.

But be aware that wrapping the baby for a long time is not conducive to the growth of the baby; when the baby wakes up, you should open the package; be sure not to “candle the package”-wrap the baby upright, just like a candle.

“Candle packs” are harmful to the development of newborns.

  Snoring: When a newborn is anxious or eats something wrong, it will continue to snore, and the baby is very uncomfortable.

An effective solution is that the mother hits the bottom of the baby’s feet with her middle finger, causing her to cry for a few times. When the crying stops, the snoring also stops.

If not stopped, the above method can be repeated.

  Skin erythema: Skin erythema may occur in the first few days of life of a newborn.

The erythema varies in shape and size, and is bright red in color, distributed throughout the body, mainly in the head, face, and trunk.

Newborns have discomfort, but usually disappear after a few days, rarely more than a week.

When erythema appears in some newborns, it is also accompanied by peeling.

Neonatal erythema does not pose any threat to health, and it does not need to be treated, and it will subside on its own.

  Nasal congestion, sneezing: Newborn nasal mucosa is developed, capillaries are dilated and nasal tract is narrow.

When there is secretion, nasal congestion occurs in newborns.

Novice parents need to learn to clean the nasal passages for the baby.

Newborns sneeze when they get cold when they bathe or change diapers.

This is the body’s self-protection, not necessarily a cold.

  Sweating: the palms of the newborns, the soles of the feet are easy to sweat, and the head sweats slightly when sleeping.
Because the development of the central nervous system of newborns is not yet perfect, the temperature regulation function is poor, and it is susceptible to the external environment.

When the surrounding temperature is high, babies will dissipate heat by evaporating moisture and sweating from the skin.

Therefore, mothers should pay attention to the temperature of the room and the circulation of air, and must provide sufficient water to the baby.

  Thinning and occipital alopecia: The hair quality of newborns has a great relationship with the mother’s nutrition during pregnancy.

In the infant period, the baby’s hair quality is closely related to the family genetics.
Neonatal occipital alopecia is not a unique sign of calcium deficiency in newborns. Harder pillows, iron deficiency anemia, and other malnutrition diseases can cause occipital alopecia.
