Problems solved by technology

[0007] Strain elastography, because the external force applied by the operator varies, this method cannot define the absolute value of the cervical hardness, and at the same time, due to the lack of reference tissue around the cervix, the elasticity measured by the strain elastography cannot be used as a strain ratio, so this method It has limitations. At the same time, this measurement method is easily affected by multiple factors such as the operator's applied force, position, fetal activity, and pregnant w

Embodiment 1

[0057] The cervical ripeness of pregnant women with induction of labor at term was assessed using a predictive model formula, including:

[0058] The evaluation objects are some cases of term singleton pregnancy premature rupture of membranes or artificial water rupture. The basic situation is shown in Table 1 below:

Embodiment 2

[0079] Cervical ripening in pregnant women with induction of labor at term was assessed using a scoring system that included:

[0080] For the cases listed in Table 1 above, the detection values ​​of the indicators listed in Table 2 above were obtained by the same detection method as in Example 1, and then the CL values ​​and IOS values ​​were scored according to the scoring criteria in Table 5 to obtain CL values. After the respective scores of the value and the IOS value are obtained, the total score is calculated by adding the two together. The scoring results are shown in Table 6.

Abstract

The invention provides a method for evaluating the cervical maturity of a pregnant woman to be induced of labor in a full month, which comprises the following steps of: measuring the length (CL) of a closed section of a cervical canal and/or the average strain level (IOS) of an inner mouth area of a cervix of an evaluation object individual, and then substituting into a prediction model formula to carry out probability calculation, or scoring measured values of the CL and the IOS according to a critical value; and integrating the evaluation results of the CL and the IOS to obtain a cervical maturity evaluation result. By means of the method, the cervix uteri state can be evaluated more accurately, objectively and safely, and by taking the cervix uteri state as an important indication, an obstetrical department can be guided to clinically select a proper labor induction mode or a proper spawning induction medicine. The invention further provides a device and a computer readable medium for evaluating the cervical maturity of the full-month pregnant woman to be induced of labor.

Description

technical field [0001] The invention relates to the field of medical data analysis, in particular to a method for analyzing and evaluating cervical ripeness, in particular to a method and equipment for evaluating the cervical ripening degree of pregnant women who are expecting to induce labor at term. Background technique [0002] Cervical ripening refers to the degree to which the cervix softens, shortens, disappears and dilates before delivery. Induction of labor in the third trimester of pregnancy is to initiate the labor process by means of drugs and other means before natural labor to achieve the purpose of childbirth. It is one of the commonly used methods in obstetrics to deal with high-risk pregnancy. At present, the clinical methods of labor induction mainly include artificial membrane rupture, intravenous drip of oxytocin, etc., and the use of different methods of labor induction is largely based on the degree of cervical maturity. [0003] In the prior art, the a...
