The fetus is the part of the fetus presented in front of the plane that passes through the mother's pelvis through which the throne will enter and progress according to its mechanism and go out. Most fetuses go into labor with a crown when the baby's head bows well. However, in rare cases, there is an abnormal pregnancy and it is necessary to understand so that the birth is convenient and safe for both mother and child.
1. Pregnant ass
A fetus with an inverted buttock or fetus is a longitudinal throne with a head above, buttocks or legs on the bottom. There are two types of butt houses:
- The buttocks are sufficient with folded buttocks and lower 2 ts, the fetus has the form of sitting equal to the uterus chamber.
- The buttocks are missing when only the buttocks or legs or knees when entering the throne.
The buttocks account for only 3% to 4% of all births, much less common than the crown but are more common abnormal pregnancies than the face and forehead.
The cause of the buttocks may be premature labor when the fetus has not yet been adjusted to a throne, or there are factors that interfere with the normalized process of the fetus such as the uterus of the underdeve developed mother, the uterus with fibroids, septum, placenta or fetal malformations such as amniotic mitigation, hydrocephalus…
Women are able to self-identify the buttocks when they see that the fetus is often prone to pedaling in the hypothage and the sensation of one side lowering the ribs due to the reinstrict pinching. Palpation of the abdomen still sees the uterus is ovate, longitudinal axis but the most obvious hearing of the pregnancy is across the navel or on the navel.
During labor, a vaginal examination when the cervical is open will not see a round face as hard as the crown, but will see the top of the sd bone, buttocks or legs. However, ultrasound will be a commonly used means of determining the buttocks, single pregnancy or twin pregnancies as well as the size of the pregnancy in order to choose the appropriate method of birth support.
2. Pregnant face
The face is the head with the maximum face of the fetus, which can appear from the beginning or as a consequence of the crown when the child does not bow well.
The fetus has a face that accounts for 0.2% of all types of stars during labor.
The cause of the formation of the face consists of factors that cause the head to back up or prevent the head from bowing well. On the mother's side, the cause may be asymmetry between the head and pelvis, due to tumors in the pelvis such as uterine fibroids… On the fetal side, the fetus has a large neck, goiter, large chest, cranial malformations … accounts for the majority in cases of the face. In addition, the pregnancy of the face is also caused by extra parts such as umbilical cord wrapped around the neck, each other clinging low, multiple amniotic fluid …
Abdominal examination finds that the crown is similar to the crown, only when touching the deep groove between the back and head, which is the groove of the neck, also known as the "axe" sign. During labor, if the amniotic head is still high, it will be difficult to touch the face. When the amniotic membrane has ruptured, the cervical enlarges, a palpable vaginal examination of the mouth, nose, cheekbones, arches will help determine the face.
3. Crowned forehead
The forehead is an intermediate form of pregnancy between the crown and the face, i.e. the head is not bent well and the face is not maximum. Therefore, most foreheads are only detected when they have entered progressive labor at a very rare rate, with 1/3000 to 1/1000 of all types of houses.
The cause of the forehead is similar to the cause of the face when it includes all the reasons why the bow of the fetus is obstructed. In particular, pelvic head asymmetry is always the most common cause. Besides, the forehead can also be a consequence of the doctor when performing an external rotation of the pregnancy. Despite this, up to 30% of cases do not find a cause.
Abdominal examination when there is a forehead is generally no different from the face with the nape of the neck not as deep as the face but will palpation of the chin. However, the chin mound is not palpable if the examination through the vaginal fall when the cervical enlarges while still being able to touch the nose and mouth like the face.
4. Horizontal crown
The horizontal throne is also called the shoulder throne when the longitudinal axis of the fetus cuts the mother's longitudinal axis into a right angle. It will be called a throne if the vertical axis of the fetus cuts the mother's longitudinal axis to create a sharp angle. However, this is also just a temporary form of throne, the fetus will be adjusted to a vertical throne or a real crossing into labor.
The horizontal star accounts for about 0.5% of the types of stars when entering labor.
The cause of the throne on the mother's side is that childbirth is many times leading when the rate of access to the throne in the third childbirth will increase tenfold compared to the person giving birth. The pasty abdominal wall causes the uterus to pour out first, causing the position to be horizontal or inclined for the fetus. In the case of a child, the horizontal star may be due to a narrow pelvis, uterine malformation or a forward tumor that prevents the pregnancy from turning its head. On the side of pregnancy, prematurebirth , the second pregnancy in the twin pregnancy or still still-death pregnancy is easy to enter the horizontal throne due to the inability to adjust. Besides, if each other plays the striker, multiple amniotic fluid or short umbilical cord is also easy to lead to the horizontal.
In contrast to the longitudinal types of throne, the horizontal throne is an abnormal form of pregnancy that is very noticeable when touching the abdomen. The abdomen of the maternity is not ovate, but the raft is on par with the bottom of the uterus almost across the navel. When palpation will not see the fetal pole located at the bottom of the uterus, but the fetal head is found on one side of the mother and the buttocks on the other. Besides, the palpitations on the backbone will not see anything. At the same time, it is also necessary to determine where the fetal back is located. If it is the front back, a solid plane will be palpable running across the abdomen and vice versa, if it is the back, it will only palpation of the verses.
During a vaginal examination, the most important sign is that neither the head nor the fetal buttocks are seen. If the cervical enlarges and the presentation of the pregnancy falls lower, the shoulder blades and collarbone can be further touched. In the event of a long course of labor, the amniotic fluid has ruptured, a fetal shoulder can get tightly into the pelvis and is usually accompanied by the prosthesis of one hand, arm to the vagina or sticking out of the mother's.
5. Complex pregnancy
The intricate pregnancy is to describe the fall of a genus along the throne and both move into the subframe. Most commonly, the crown has a forearm or a forearm. Less common is one or two legs with the head or one hand with the buttocks. Not only that, the complex pregnancy is often accompanied by umbilical cord prolapse, which makes the prod prod prod pron "
The causes of the complex star include all the reasons why the throne does not occupy the entire upper waist such as polyavorous, high head, narrow pelvis, small pregnancy,…
In summary, the abnormal fetus is the presentation of the fetus when entering labor not equal to the crown of the fetus. Despite the relatively low proportion, the abnormal pregnancy always makes the operation of childbirth very complicated and difficult. Therefore, women need to have regular pregnancy examinations, especially near birth days, to predict the pregnancy, choose the safest method of birth. In case of the inatability of normal birth, the doctor will prescribe a cesarean section to ensure the safety of both the mother and the baby.
