Group/Cohort Intervention/treatment
Induction of labor
200 women all are primigravida between 37-42 weeks gestation to whom induction of labor will be carried out in the casualty of Ain Shams University Maternity Hospital. All participants will have an assessment of the cervix by both Bishop score system and transvaginal measurement of cervical length.
Other: Bishop score
calculation of modified Bishop score in numbers by digital vaginal examination

Other: cervical length
measuring cervical length by trans-vaginal ultrasound




Primary Outcome Measures :
  1. Cervical Length Prior to Labor Induction [ Time Frame: 24 hours ]
    median cervical length measured by transvaginal ultrasound in centimetres

  2. Bishop Score Prior to Induction of Labor [ Time Frame: 72 hours ]

    median Bishop score assessed by digital vaginal examination as follows:

    1. Cervical dilatation in centimeters will be given a score of zero if closed, a score of 1 if 1-2 cm dilated, a score of 2 if 3-4 cm dilated and a score of 3 if 5 cm or more dilataion.
    2. Effacement of the cervix will be given a score of zero if 0-30%, a score of 1 if 40-50%, a score of 2 if 60-70% and a score of 3 if 80% or more.
    3. Station of fetal head will be given a score of zero if -3, a score of 1 if -2, a score of 2 if -1 to zero and a score of 3 if 1 or more.
    4. Consistency of the cervix will be given a score of zero if firm, a score of 1 if medium and a score of 2 if soft.
    5. Position of the cervix will be given a score of zero if posterior, a score of 1 if mid position and a score of 2 if anterior. So, a total score (sum of all scores) of zero at a minimum to 10 at a maximum can be estimated.

    Note that a score more than 10 means patient is in labor not needing induction of labor.
