Repeated dilation and curettage may lead to miscarriage

　　Repeated dilation and curettage may lead to miscarriage . Some miscarriages occur in the fifth or sixth month of pregnancy. In these patients, B-ultrasound examination confirms that the child is developing normally, but the miscarriage occurs very quickly. They often complain of "stomach pain, and within ten minutes, the baby will come out." ”The reason is that most of these patients have a history of repeated dilation and curettage. Repeated dilation and curettage can cause cervical damage. As the pregnancy months increase, the pressure in the uterine cavity increases, eventually leading to the opening of the cervix and miscarriage.

　　Countermeasures:

　　①Once an unplanned pregnancy occurs, the time for dilation and curettage should be scheduled after 45 days of pregnancy. The reason is that the cervix is ​​hard and small 45 days ago, and repeated forced dilation can easily cause damage to the cervical pedicle tissue, making it difficult to withstand the heavy intrauterine pressure caused by pregnancy.

　　②If cervical damage is found during pre-pregnancy examination, cervical suturing should be performed in advance. Cervical cerclage can also be done after 4 months of pregnancy. 》》》 Various names for the vagina in ancient times
