Bishop score, fundus height - clasp/fundus distance)

Cervix score according to Bishop is nowadays the most used method used to evaluate the readiness of the mother's organism to induce vaginal delivery . This scoring system evaluates a total of five parameters: shortening and dilatation of the cervix, distance of the guide point below the plane passing through the spinae ischiadicae, consistency and position of the cervix.

Bishop score rating

The first three parameters are evaluated with points in the range of 0-3. The remaining two parameters then range from 0-2 points.

Previously, the Cervix score according to Bishop was used for multiparous women, currently it is for women who have not yet given birth.

Evaluation of individual parameters

Shortening of the cervix

This parameter is measured in percentage. If we measure the length of the cervix, we measure it in centimeters. Shortening and length are classified into four analogous degrees and 0-3 points are also evaluated.

Cervical dilation

From a clinical point of view, this is the most important parameter. The dilatation is measured in centimeters and is classified into four degrees in total, with a score of 0-3 points.

The distance of the leading point below the plane passing through the spinae ischiadicae

Distance is also measured in centimeters. Four grades are also classified and, as with the previous ones, 0-3 points are evaluated.

Cervical consistency

Here, only three grades are classified and the evaluation ranges from 0-2 points.

Cervical position

As with consistency, three grades are also classified and points are scored in the range of 0-2.

Calculation of the Cervix score according to Bishop should be part of the Indication protocol.
