结局指标
主要结局
Cervical Length Prior to Labor Induction
时间窗: 24 hours
median cervical length measured by transvaginal ultrasound in centimetres
Bishop Score Prior to Induction of Labor
时间窗: 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.
