Medical technology has been developed when the delivery process is considered to be \"in life-for small life\", visible in many accidents occur during labour conditions. Although modern science has to minimize the dangers, but still some gynecologists by surprise, or into the save mother or the child\'s dilemma. The following lists the top 10 during the accident, in order to let the mother can take precautions, prepared in the most relaxed mood to greet the arrival of the new life.
1, placenta previa
\"Placenta previa\" the vast majority occur in mothers after 28 weeks of pregnancy, will accompany bleeding, which is characterized by painless bleeding, often in the middle of, physicians usually rely on the ultrasonic examination for diagnosis, however, sometimes even ultrasonic check out.
Due to placenta cover to the cervix mouth, when the fetus comes out from the cervix, a contraction of cervical will expand, a expansion and placental hemorrhage, most pregnant women do not feel pain, but the blood loss is more than one at a time.
\"Placenta previa\" and can be divided into four types: full-and partial-type, edge and low. In addition to full-and part-caesarean section with placenta previa pregnant women need outside, edge type and low-placenta previa can consider natural delivery. However, blood loss if very much more threat to the safety of mothers, physicians are the purpose of caesarean, and disturbed fetal. Therefore, we recommend that pregnant women must stay in bed of placenta previa, less activity, not holding back urine as possible, so as to control bleeding.
2, premature separation of placenta
\"Ablatio Placentae (Placental Abruption)\" a condition that is very difficult to diagnose. Because should generally only after the birth of the placenta and uterine isolation, but the \"Placental Abruption\" is the placenta had stripped before the unborn fetus. As the placenta is the source of fetal nutrition and oxygen, so once the placenta after the split, there was no transmission of oxygen to the fetus, fetus if the fetus is already infected, even if delivered by surgery, is still very dangerous, are likely a lot of problems at the newborn stage, hypoxia phenomena occurred very soon.
\"Placental Abruption\" is the biggest feature of hemorrhage and severe abdominal pain. If in the process of childbirth, and childbirth pain mixed in with this pain, will make it difficult for doctors diagnosis; if a pregnancy occurs at 33-35 weeks, as has been a significant pain, and the entire uterus becomes rigid, so doctors can use some of the instruments and means to determine the need for emergency treatment.
\"Placental Abruption\" often related to pregnant women with hypertension, diabetes, and placenta previa, but more of a reason is not clear. Doctors in addition to judging by maternal blood amniotic fluid is sometimes must rely on ultrasonic examination and clinical symptoms to diagnosis, for example: obvious changes in the fetal heartbeat? Even if not a Placental Abruption, but significantly slow fetal heart rate, doctors as soon as possible the purpose of caesarean section, to ensure the safety of children.
3, fetal Anoxia asphyxia
This is the so-called \"fetal distress\", refers to the heartbeat of the fetus change to figure out he has a hypoxic or uncomfortable phenomenon, that is, when a low oxygen content in fetal blood to a certain extent, fetal heart beat slows.
\"Fetal distress\" can appear in many different situations, such as fetal heart beat fast, slow, small, the amniotic fluid in the fetal heart rate changes, hypoxia causes mainly umbilical cord are oppressed, too strong uterine contractions, poor function of the placenta and umbilical cord around neck, broken water too long without amniotic fluid, and so on.
Due to fetal distress, its heartbeat changes, so doctors will observe the fetus with fetal heart monitor changes in heartbeat. Normal fetal heartbeat should be in the 120~160 beats per minute, and renders the fluctuations in the curve. If fetal heart beat more than 160 beats per minute or less than 120 times, prompting fetal intrauterine hypoxia condition exists.
Of course, not every fetal heart beat slower fall into distress, some distress for short, may soon recover, doctors only to maternal oxygen infusion of a lot of liquid, or mother side lying can improve the situation. Event of severe fetal distress, endangers the life of the fetus, doctor measures will be taken, let the child birth as soon as possible.
4, pregnancy-induced hypertension syndrome
If women occurred during pregnancy-induced hypertension, proteinuria, and edema, or one of two types of symptoms, is called \"pregnancy-induced hypertension syndrome\", that is not high blood pressure before pregnancy, but at the beginning of 20 weeks of gestation when these symptoms occur, it can be diagnosed as \"pregnancy-induced hypertension syndrome\".
When a pregnant women\'s blood pressure is too high, leads to confusion, liver enlargement, fundus bleeding, abnormal liver function, brain lesions, and so on, serious eclampsia, and threats to maternal and child life. At this point, the physician often forced by the situation and assist the fetus of pregnant women gave birth earlier. If time allows, it will first consider the oxytocin, if time is pressing, or invalid oxytocin, immediately the purpose of caesarean section.
In terms of treatment, in addition to early delivery, physicians will advise pregnant women to bed rest, eat high protein food to reduce edema, are in a quiet environment as far as possible, taking appropriate antihypertensive drugs. There are now studies suggest that pregnant women taking low-dose aspirin (50~100 mg daily) or large amounts of calcium (more than 2 grams a day) may have a role to prevent pregnancy-induced hypertension syndrome.
5, cord prolapse
\"Prolapsed umbilical cord\" vast majority occurred in the fetal position not is, breaking under water. Fetal position if the fetus is \"foot\", which is in the uterus feet down, when sliding one foot when the umbilical cord will often follow slide. If the normal fetal position, but still no fetal head to enter pelvic cavity fixation, if prolapsed umbilical cord, fetus but more dangerous, because the parent event of a water break, cord release bend, fetal head probably because of oppression to drop directly into the umbilical cord, or fetal their own
Blocking blood supply, which can cause very serious fetal hypoxia in 3 minutes or die.Therefore, doctors usually will make maternal \"head foot high\" lying, or fetal body left oppression version so that location, within the hand back into the birth canal, on the fetus to the top, make the fetus not oppression to the umbilical cord, and then hurry purpose of caesarean.
In the course of operation, still below the maternal health care personnel, assisting the main physician fetal resist and push upwards with a hand, to facilitate the physicians directly as soon as possible, pull the fetus from above. So, in the event of fetal umbilical cord prolapse, pregnant women can best lay flat and rushed to the hospital by his family as soon as possible.
6, births and postpartum hemorrhage
Inherently hemorrhage during labour, for example: uterine bleeding after delivery of the fetus and the placenta. In the course of delivery, bleeding if more than 400 ml, considered to be \"bleeding\".
If maternal bleeding during, when delivery of the fetus is unable to as soon as possible, physicians usually considered women\'s safety and purpose of caesarean section, and then, look for bleeding point, take measures to stop bleeding.
Which births and common causes of postpartum hemorrhage are uterine contractions or obstetric laceration, doctors will take certain measures to stop bleeding, including wound suturing, strengthen uterus or placental shave will not completely split as far as possible, and so on.
If you continue to bleed after processing, you have to open abdominal cavity, maternal great vessels of the Uterine artery, or some special binding, \"vascular ligation\" to reduce the amount of bleeding. If you still not found bleeding point and, if necessary, have to take \"hysterectomy\" to stop bleeding.
If even the hysterectomy are invalid, should take the \"oppressive\" hemostasis, vascular vascular embolization of photography to do even bleeding. Therefore, such or postpartum hemorrhage is always in the middle of gynecologists are headache, because the bleeding is difficult.
7, uterine rupture
More than 20 years ago, \"uterine rupture\", the vast majority occur in too many birth fetal mother, is due to the long stretch of uterus, resulting in very thin uterine wall is bracing, maternal cause uterine rupture in the strong contraction of time.
In recent years of \"uterine rupture\" is common to do caesarean birth mother, in her production when a tire to natural childbirth. However, such a rupture were seen more \"straight caesarean section\", and now the new \"crosscut\" caesarean section less uterine rupture occurs.
Uterine rupture of precursors, including slow fetal distress phenomenon appears, touch the fetus from maternal abdominal clearly of a limb or torso. If the maternal belly expansion badly, this is a hemorrhage, and the amount of bleeding is very large.
Therefore, when maternal uterine rupture, physicians choice as soon as there is only one--the purpose of caesarean section.
8, early water break combined with infection
Think water break in pregnant women in the past 24 hours, easy infection of fetus, now think water break after 18 hours, the chances of infection of the fetus will increase. Maternal water break is it must be the purpose of caesarean? In fact, the only in fetal have signs of infection, and is only required if not soon after vaginal delivery operation. In short, gave birth to the child as soon as possible to the principle.
Under normal circumstances, maternal fever began to emerge, heartbeat, smell the amniotic fluid, stomach pain, blood routine examination when there is a marked increase white blood cells, will be able to figure out the fetus already have signs of infection. If maternal water break up to 48 hours, there have been infected, doctors will recommend the use of antibiotics, and appropriate ways to assist delivery of the fetus as soon as possible.
If the fetus has severe infection when it could not immediately give birth, physicians for maternity caesarean surgery immediately. However, to life due to infection.
Therefore, maternal occurs once in the 33-35 pregnancy week water break, under the best of health as soon as possible the fetus because of fetal maturity is sufficient at this time, never miscarriage for too long, otherwise it will increase the chances of infection.
9, dystocia
\"Birth\" is when halfway through the time of delivery, delivery of the fetus could not smoothly through the birth canal. Obstructed labour is not caused by the giant baby, however, giant babies do more easily lead to dystocia.
Dystocia has two cases: the first is \"shoulder dystocia\", that is, fetal head out, but the shoulders are stuck. At this point, a medical staff from maternal help push above his mother\'s stomach, another helped turn the fetus. But this easy to let your child have a clavicle fracture or injury of the children of the brachial plexus. Second birth is less common, it is the maternal fetal position not being trying to natural childbirth, but after the body of the fetus, fetal head is stuck. Its legacy and \"shoulder dystocia\", are easily brachial plexus injury child, even skin laceration. Fortunately this fetal brachial plexus injury through a variety of treatment to recover.
Due to the difficult birth occurs when doctors had been unable to for the purposes of maternal caesarean, and 90% of the fetus could not be pushed back, so doctors must vary from person to keep the fetus squeezing the mother\'s birth canal, sometimes deliberately manufacture fetal clavicular fracture, make the fetal shoulders take up space as a whole smaller so that it can smoothly through the birth canal.
10, amniotic fluid embolism
The so-called \"amniotic fluid embolism\" is a large number of amniotic fluid in the blood of pregnant women, caused by embolism phenomenon, and drains away blood coagulation factors, resulting in dysfunction of blood coagulation, maternal shock and hemorrhage and even death. Because of this situation almost cannot prevent or predict in advance, so that the maternal mortality rate as high as 90%.
When maternal amniotic fluid embolism occurs when, if the hospital does not have adequate supply of blood, even entering large amounts of blood coagulation factors, will was consumed in large amounts of amniotic fluid into the blood. Therefore, physicians the most common way is to enter large amounts of fresh blood to mother, but even so, also often cannot weaken it
Kinds of blood flow or circulation function failure of more than.
