How long will it take to give birth if the cervical canal is 1 cm

Cervical cancer is a common gynecological malignant tumor. The disease is more common in women aged 35-45. The incidence rate has increased in recent years, seriously endangering the life and health of women. If the cervical canal has not retracted by 1cm, and there are regular uterine contractions in clinical practice, and the regularity is once every 3-5 minutes, and lasts for more than 30 seconds.

It takes about two hours for the cervical canal to completely shrink. Because if it is the first delivery, the cervical opening will be relatively tight, so the expansion will be relatively slow clinically. If it is a primipara, if the cervical canal is 1 cm, it will completely disappear in about half an hour clinically. Therefore, first-time mothers are different from first-time mothers. It is recommended to make relative preparations, rest well when the uterus contracts, and not consume too much energy. When entering the second stage of labor, pregnant women need to use their strength to give birth, so they need to conserve their energy, rest as much as possible, and eat as much as possible.

Endocervical canal - examination

(1) Vaginal examination: Observe the location, shape, and size of the external opening of the cervix, analyze the amount and characteristics of the cervix, and check whether there is cervical erosion or growths, etc. Pay attention to whether there is cervical lifting tenderness and paracervical tenderness. At the same time, the endocervical mucus is tested for intestinal pathogens. If necessary, do a scraping or colposcopy.

(2) Probe inspection: Simple and easy to use, it can detect the direction, length and proportion of the cervical canal to the cervix, whether there is stenosis, adhesions and the tightness of the internal cervical os. For those suspected of abnormalities, further angiography should be considered.

(3) Hysterography: Hysterography can not only detect uterine and bilateral fallopian tube diseases, but endocervical canalography is also very helpful for the study of infertility. When degreasing agent is used and the contrast examination equipment does not affect the developing solution of the neck tube, the length and shape of the neck tube can be better displayed. It can confirm the diagnosis of growths in the cervical canal, congenital malformations, stenosis, adhesions and uterine flexion. Uterine fibroids, cysts, etc. in the cervical canal appear as smooth-edged fractures on cervical canal films; while the edges of cervical canal adhesions are mostly irregular, jagged shapes. The hypoplastic cervix is ​​slender, while the cervical canal lumen of tuberculosis is spacious and has brush-like changes. Contrast examination can also be used to measure the length and proportion of the cervical canal and uterine body. It is especially effective in patients with genital dysplasia and cervical stenosis who have unsuccessful probe examinations.
