Definition and causes
There are broadly three factors to determine whether it will be a difficult and protracted birth, and whether there may be a need for tools at birth.Passage: Anatomical relationship with the woman that makes the child may find it difficult to pass. This is most often in very young women, where the birth canal is smaller than usual. In addition, previous pelvic trauma of being the cause of the pelvic bones are placed slightly differently than at normal anatomy. Barnet: Is the fetus unusually large for the birth canal, it can lead to difficult birth or even impossible to make the crossing. For example, hydrocephalus (water on the head) of the child, may be the reason that it is difficult to pass. If the child is in an abnormal fetal position, birth can also hampered. PressuresIf véerne is insufficient, or if the woman because of the stunning evolution has created pressure force, it may be the cause of the birth can not happen without tools. Precautions and diagnosis
If the birth of the obstacles are of a nature that can be foreseen, such as hydrocephalus, or anatomical relationship with the woman who makes the birth canal narrow, you can schedule a Caesarean. These conditions can be detected before birth should be initiated by ultrasound scanning of the fetus or by gynecological examination of the woman.Treatment of birth barriers
If the birth of the obstacles caused by abnormal fetal position, it may be necessary to use the tools at birth.
If the lack of progress in childbirth due to inadequate contractions of the uterus, can be given a synthetic hormone that stimulates véerne.
