1, early pregnancy bleeding and fetal atrophy

In early pregnancy, often there will be blood-like vaginal discharge, or vaginal bleeding, and some accompanied by mild abdominal pain, terrified mothers who had just become pregnant, their unborn fetus, therefore fear that one day. Such cases as "threatened abortion."

Clinically, early pregnancy, about 1 / 4 of bleeding may occur, the reason may be physiological in nature implantation bleeding or pathological lesions of the cervix. In particular, bleeding after sexual intercourse, but also whether there should be diagnosed with cervical polyps or cervical bleeding. Most of the bleeding will be maintained for several days or even weeks, doctors will refer patients for more than bed rest and to stop the sexual life, if necessary, to give progesterone or against the treatment of cervical lesions do.

If 6 ~ 7 weeks of pregnancy when the ultrasound examination there was still no fetal heart rate, we must doubt whether they were "atrophic embryo sac." The patient was informed that the results of abnormal embryos, often sad and only themselves to blame for this unfortunate remiss. In fact, because of natural factors that result in miscarriage risk as high as 15% ~ 20%. Shrinkage of about 60% of embryos because the fertilized egg chromosomal abnormalities, or a fertilized egg itself is a problem caused by natural selection are under natural selection, therefore, expectant mothers, expectant fathers have experienced such a situation need not be guilty. Readily accept and cooperate with physicians to make the appropriate treatment, is should have the correct attitude.

2, cervical insufficiency

Cervical insufficiency is the cervix, "painless expansion" can not lock, allowing amniotic prolapse led to broken water abortion. This mostly occurs in mid-gestation, and the medium-term repeatability of pregnancy can cause miscarriage.

Cervical insufficiency is largely attributable to cervical dysplasia is a congenital and acquired cervical injury. Congenital about 30% to 50%, including a mother taking DES during pregnancy these drugs. Acquired reasons, most with the abortion, or have experienced early cervical cancer on cervical cone excision.

The main treatment of cervical insufficiency during pregnancy is 14 to 16 weeks of the purposes of McDonald cervical suture, but the possible side effects of this operation is to break the water, bleeding or infection.

3, fetal intrauterine growth retardation

Mothers for check-ups, the most like to ask questions of the words were: "baby weight normal? Have multiple up?" If the doctor's answer was "a bit smaller!" Prospective mothers will anxiously endless. In fact, the baby's weight, there have been a light weight, body length are of different sizes, as long as the normal growth curve, it should surprise no one. However, after 37 weeks of pregnancy if the fetus weighs less than the number of weeks of pregnancy the fetus of normal body weight by 10 percentage points, but also the merger with the mother or the placenta problems, such as too little amniotic fluid or placental calcification, it may be fetal growth retardation.

If the fetal head circumference and abdominal circumference are smaller, known as "shaped growth retardation, both said," The main reason there are bad mothers weight gain, intrauterine infections (such as measles, syphilis), congenital abnormalities, chromosomal abnormalities and so on, however, also may be due to the smaller size of the parents, based on genetic factors, the fetus will naturally smaller.

If the fetal head circumference and normal, and only a smaller abdominal circumference is called the "uneven nature of growth retardation, said," the fetus in the third trimester will be subject to adverse factors, the common causes of a mother with anemia and kidney disease, heart or blood vessel leading to placental insufficiency, for multiple births or fetal placenta, umbilical cord disorders. In addition, the mothers are malnourished or have smoking, drinking and other bad habits, as well as pregnant women, disorder medication and so on, are likely to cause fetal growth retardation.

Growth retardation of the fetus, fetal distress occurs in the production of a high percentage, so the importance of early diagnosis. If pregnant women found to have the phenomenon of fetal growth retardation, in addition to the factors can be corrected for the correction of the above-mentioned things, if necessary, be given on induction to prevent any eventuality.

4, antepartum haemorrhage

Antepartum haemorrhage refers to the pregnancy vaginal bleeding after 28 weeks. Occurs mainly for two reasons:

(1) abnormal placenta: placenta previa, placental abruption the most common.

(2) cervical and vaginal diseases: such as cervical erosion, cervical polyps or cervical cancer. In addition, vaginal trauma or foreign body insertion, etc. can also cause bleeding.

(3), urinary tract infections caused by hematuria.

(4), hematological diseases, such as: coagulation dysfunction.

Antepartum hemorrhage occurs when the doctor and find out as soon as possible causes of bleeding. Ultrasonic be able to tell whether or placenta previa, such as determining non-placenta previa, whether there should be further confirmed cervical or vaginal disease. In addition, urinalysis and coagulation testing can provide further information. In certain special circumstances, such as placental abruption, cesarean section if the conditions have, so as to produce suitable.

5, malposition

Breech, transverse, oblique, surface production-type Dengjun called malposition, of which the highest proportion of breech presentation. Expectant mothers are concerned about your baby's fetal position, often to ask the doctor during pregnancy fetal position on the issue soon. In fact, the 3 months before the embryo in a floating state, all the time does not change position. The fetus just six months ago, about half of the baby's position is not correct, until 32 weeks later, the proportion of malposition was reduced to 10%. Therefore, the baby's position is not being pregnant 8 months ago, is quite common, parents need not worry because most of the baby in 8 months later, would be very rules to regularization.

Maternal polyhydramnios, abdominal muscle relaxation through the maternal, uterine fibroids, double-angle uterus, placenta previa, multiple pregnancy such as a higher risk of malposition In addition, fetal congenital anomalies, such as: congenital hip dislocation, chromosomal abnormalities , cerebral edema, the higher the chance of breech presentation.

The risk of breech presentation by vaginal high, because the fetus can not be the mother's pelvis, hip is full, their production occurs when a higher chance of umbilical cord prolapse, and also more prone to the phenomenon of fetal hypoxia, or even cause fetal death. In addition, the fetal long bone fractures, spinal cord injury or severe laceration of the mother's birth canal chance, the first output bit higher than 10 times. Therefore, it is recommended that such mothers for cesarean section is safer.

6, premature rupture of membranes

Refers to the production of premature rupture of membranes in the absence of pain before the rupture of amniotic membrane has been the natural result of amniotic fluid. Reproductive tract infection, polyhydramnios, multiple pregnancy, amniotic fluid puncture, uterus regurgitation, etc., may result in premature rupture of membranes.

Pregnant six months ago, if you are unfortunate rupture of membranes, fetal survival rate is not high and a lot of premature birth complications, the general proposal to terminate the pregnancy. 6 ~ 8 months of pregnancy during the breaking of water, consider a conservative looking forward to therapy, according to the situation given antibiotics, tocolysis drugs or steroids to enhance fetal survival. After 34 weeks of pregnancy water break, then the first assessment of fetal lung maturity, if the immature is the first tocolysis and bed rest until the babies mature re-induction of labor.

7, premature

Most of the early uterine contraction may be just false labor pains, but, if the uterine contraction frequency of four times every 20 minutes or more, or 1 hour and there is more than 6 times, and the progressive thinning of the cervix has expanded the case, that is, Premature sexual pain should be bed rest and tocolysis with the doctor to guide the use of drugs.

8, fetal distress

Fetal distress is a choking phenomenon of fetal hypoxia. Normal fetal heart rate is about 120 ~ 160 times per minute. Fetal heart rate is too slow or too fast, there is variability in heart rate or poor, have to wonder if there is a potential fetal distress.

Fetal distress because of prolonged pregnancy, pregnancy induced hypertension syndrome or diabetes, caused by placental dysfunction caused by chronic distress, in addition to the uterine wall muscle contraction caused by a temporary cessation of blood circulation can also lead to acute distress.

For check-ups, they generally use the Doppler fetal heart tones, the purpose is to ascertain if there are potential fetal distress, if an exception occurs, will ask the mother to accept a 30-minute fetal monitor checks to determine further processing.

Most of the fetal distress, the mother can change the location to start, such as lying to the left to improve, or injection of a large number of bit by bit, or oxygen inhalation has to help. If these methods are not effective, and ultimately only way is to choose a cesarean section.

9, pregnancy-induced hypertension syndrome

Obstetric maternal blood pressure is one of the problems common, accounting for 5% of all pregnant women. Part of it also appears associated with proteinuria or edema, known as pregnancy-induced hypertension syndrome, the condition will have serious headaches, blurred vision, upper abdominal pain and other symptoms, if there is no proper treatment, may lead to generalized convulsions and even coma.

Pregnancy-induced hypertension syndrome caused by the reasons remain unclear, at present considered to be derived from a series of disease processes, fortunately, most of the observed pregnancy-induced hypertension just do not have much side effects. But severe blood complications, including intracerebral hemorrhage, kidney failure, liver failure, respiratory failure and so on, maternal mortality rates will be higher. If you can not be good medicine to control blood pressure, the termination of pregnancy is the only method of treatment. It is worth mentioning that, adequate bed rest can prevent disease progression, which is suffering from pregnancy-induced hypertension patients must bear in mind the.

10, gestational diabetes mellitus

Due to various hormonal factors during pregnancy resulting from the role of insulin resistance, forming the so-called gestational diabetes. Of diabetes on her mother's influence, in addition to controlling blood sugar is not easy, easy to obesity, but also susceptible to infectious diseases, such as urinary tract infections. In addition, the occurrence rate of pregnancy-induced hypertension syndrome will be tens of times higher than the average person as much.

In addition to fetal infant syndrome tend to have a huge lead to dystocia, chronically high blood sugar can easily lead to uteroplacental vascular disease, which leads to fetal growth retardation or even died in the womb can not be careless. Therefore, diabetes pregnant women should accept the recommendations of doctors and nutritionists, control diet or medicine to control blood sugar down are to ensure that mother and child safe.
