delivery refers to the growth and maturation of the fetus and outward from the maternal uterine discharge process. 40 pregnant week for term pregnancy, fetal development mature, weight about fluctuations Yu 2,500-4,000 grams; was born Shi weight is less than 2,500 grams of newborn in the at least has 25% has 37 pregnant week above of features: skin Ruddy, and skin Xia fat full, fetal fat, and Lanugo hair does not more, has obvious of normal hair and nails, cries sonorous, baby testicular has fell to Yin SAC within, and baby girl large Yin lip has covering Yin pedicle and small Yin lip. Therefore, more than 20 years ago, argued to re-examine concepts of alone judge immature weight. Above do not belong to preterm infants have at or so that smaller looked like. This requires special attention after birth care. During pregnancy, the uterus while increasing swell, but the uterine smooth muscle contraction has been very weak, basically in a calm state, hence not pregnant women caused by feeling. Prior to delivery to a few days, uterine contractions began to strengthen. Physiological significance of shrinkage . with two, one is to squeeze the fetus, the period within the uterus gradually go into labor before the normal location; the second is that the uterus up for easy delivery. Following each new delivery method from the delivery process and measures to give a brief introduction.
human childbirth is usually divided into three phases. The first stage, low frequency of uterine contractions, contraction force weak, its main role is to make the uterus more expanded. To the end of this stage, package outside the fetal membrane rupture, amniotic fluid is expelled from the body. When the uterus mouth has completely opened up, when the baby’s head had fallen to the pelvic, second phase is under way. Since then, uterine contractions become fast and powerful, this is called perinatal array contraction. Array-shrink function is to squeeze the fetus out of. Whenever the array contraction occurs, women should tie to hold campaign closed glottis, the abdominal muscles and diaphragm contraction, which would contribute to the delivery. Usually after such a secondary array reduce interruption occurred, continued strong contractions of the uterus, after 20-30 minutes, this is the third phase. Contractile effect of this phase is extruded in vitro placental and venous sinuses of the uterine wall and damaged vascular pressure tight to avoid too much bloodshed. After delivery is completed, the uterus is shrinking, but cannot be recovered to its state before the pregnancy.
prior to delivery notes:
1, regular hospital equipment, technology, experience is to ensure that mother and child safe place. A sign of when delivery occurs, immediately to the hospital, waiting for delivery.
2, caused by uterine contractions during labour pain, will run through the entire delivery process.
3, uterine pain primarily in the lower abdomen, in some cases, but in one of the two above the medial or spinal column. Many women felt contractions of pain and menstrual cramps are similar, but more intense.
4, and when the fetus is born, due to the expansion of the perineum and vulva, maternal feeling a burning feeling in these parts and intense pain.
5, find a comfortable posture, deep breaths in a relaxed state, can ease labor pain.
6, delivery of the first stage to observe uterine contractions, fetal heart sounds, note capsule time; to wearing rubber finger right hand forefinger, spreads a little lubricant, gently for rectal examination, tactile Cervical Dilatation, as well as State, early maternal uterus mouth open wide (about 10cm), that is, should be sent to the delivery room ready to delivery.
7, childbirth, may occur at any time, whether it is day or night. Labor threatened, it is usually what you seem to feel the feeling seems to be nothing that occurred in the State of. First have the feeling of increased urine, walking is not applicable, then you will find a hard or abdominal waist under some pain, and menstrual pain feels similar. This feeling tells you that uterine contractions started for the first time, initially every array contraction of 10-30 seconds, with longer intervals. Gradually extend the duration of uterine contractions, and accompanied by Brown, pink or bright red outflow of blood from inside the vagina, this is known as a “show”. Show is the first symptom of childbirth is about to begin. 24-48 hours before the show is usually occurs during childbirth.
A, and
in the weeks before the birth, fetal head into the pot, you would feel relaxed some upper abdominal, breathing and appetite improved markedly, but increased urine, walk not too comfortable. This is the reasons for the decline at the end of the uterus.
B, and
delivery several days ago, was a hardening of the abdomen, may be accompanied by mild fall feel, this is the uterine contractions. Uterine contractions are often shorter duration, interval length, often occurs during the night, disappearing in the early morning, Miyaguchi does not expand. So, you don’t have to be nervous.
C, and
24-48 hours before delivery, vaginal discharge a few bloody mucus that show. Show may last a few days, every day a little bit discharged; they might suddenly overnight show. If you show more than usual menstruation, should go to the hospital in time to contact a doctor or midwife.
birth attendants do which prepared?
① disinfection vulva;
shop ② sterile towels, to prevent infection. In addition to preparing well for the General, if in the family, to prepare the cutting and sewing supplies and medicine. Deliveries to disinfect hands, wears sleeves and gloves. 1 2 vascular clamp umbilical cord cutting and disinfection may be boiled for 10 minutes; in case of quick-available alcohol disinfection of combustion. Also to prepare the plastic sheet, toilet paper, cord volume, and so on.
deliveries measures: deliveries Shi Dang fetal head dial dew larger Shi, note protection perineal, common method is: deliveries who right elbow support in delivery bed Shang, perineal Department pad to collapsed of no bacteria towel or gauze pad, will right hand thumbs and remaining four means separated, with Palm Shang supporting, arrived in live perineal, left hand holding gauze light pressure fetal head, help leaned over flexor, to pillow bone from pubic bow Xia showed Shi, called maternal mouths for short respiratory, in uterine contractions intermittent Shi let maternal though gas, left hand is help fetal head Shang Yang, Fetal head delivery slowly. After delivery of the fetus, down from the fetal nasal root with the left hand squeeze, squeeze nasal mucus and amniotic fluid to avoid inhaling gas pipeline. Up more that if the umbilical cord around neck, along the shoulder of umbilical cord can be slid down or slide from the fetal head out; if the umbilical cord around neck rings or too tight, then use any vascular clamp the umbilical cord in a circle two sandwiched in between two pliers to cut. Assist external rotation (left early position pillow, pillow and turn left; right pillow front position, turn right pillow), the right hand continues to protect the perineum, left hand gently under the fetal head compression so that shoulder before delivery of the fetus, womb head up again so that shoulder after delivery, followed by delivery of fetal body, lower limbs in succession. Amniotic fluid is poured. Umbilical cord round the final margin of about 15 cm, respectively, with two clamping of the umbilical cord blood vessels, two claws cut.
and, lastly, neonatal care, guaranteed not to block the trachea and warmth of the newborn after delivery of immediate scoring, judging there except in rooms. Since the delivery of the delivery of the fetus to the placenta, approximately 5-15 minutes, generally no more than half an hour. Postnatal observation 2 hours should be in the delivery room, taking note of uterine contractions, fundal height, amount of vaginal bleeding, and blood pressure, pulse, and so on.
after childbirth may there was a relaxed feel. However, babies born, you may be surprised, too, out of the tears of joy, or have an extremely cordial feelings.
A, fetal head moves close to vagina, vulvar and anal area because of fetal head compression pelvic floor and it is applied. Soon you will see the fetal head, fetal head to move forward with each contraction, when the contractions disappear, might be slightly backward slip into a little. If this is the case don’t be discouraged, it is entirely normal.
B, when the top of the head when you can see, midwives will tell you not too hard, because if the fetal head delivery is too fast, your skin may be torn at the perineum, to relax, in a few seconds pause for breath. If there is a serious risk of tearing, or when the fetus is in danger, you’re going to accept the episiotomy. When the fetal head when expanding vagina, you will sense of tingling, follow is a sense of numbness, this is because when vaginal tissue expansion are thin, caused by blocking nerve conduction. When
C, head delivery, baby face down. Midwives may want to check the umbilical cord, in order to ensure the baby’s neck was not umbilical cord entangled (when the baby when physical delivery, umbilical cord often stuck in the head). Then, baby head turned to one side, head and shoulders remain on the line. Midwives to clean the baby’s eyes, nose and mouth, if necessary, to aspirate liquid in the respiratory tract of infants.
D, follow the following two uterine contractions during infant body will slide out of the mother. Usually midwives under the armpit of his hand on the baby is lifted out and put them in your belly, when baby still attached to the umbilical cord. At first the baby looks a bit blue, skin is covered with small for fat and streaks of blood, cry. If the baby breathe properly, can instantly hold, and in her arms. In addition, the midwife will clean the baby’s airway again, and if necessary, be given oxygen.
E, and after delivery of the fetus, there will still be uterine placental delivery, uterine contractions, relatively speaking is pain-free. Subsequently, the doctor will clean up and tidy, as RIP vulva, partial suturing.
