Sweeping the Membranes, Cervical Length and Duration of Labor

Study Overview
=================
Brief Summary
-----------------
Sweeping the membranes in term pregnancy may shorten the cervix and reduce the time to delivery.

Detailed Description
-----------------
Cervical length will be measured in both groups. The membranes will be swept in pregnancies beyond 38 weeks by digital examination in the study group. The control group will only be examined for Bishop score. Two days later cervical length will be Measured once more.

Official Title
-----------------
The Impact of Sweeping the Membranes on Cervical Length and Labor: A Randomized Clinical Trial

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: The membranes swept group<br>This group will have a sweeping of the membranes after the 38th of gestation at hospital, in order to reduce the latency period until labor. Sweeping of the membranes is done by the insertion of examiners finger between the decidua and fetal membranes and by the circular movement of the finger, the membranes are detached from the decidua. | Procedure: sweeping the membranes<br>* The cervical length will be measured and the patient will be examined to determine the Bishop score. Later the the membranes will be swept.<br>* Other names: digital examination;|
| Sham Comparator: No sweeping group<br>This group will not have sweeping of the membranes, will only have vaginal ultrasound | Other: No sweeping group<br>* Cervical length will be measured by transvaginal USG and the patient will be examined to determine the Bishop score.<br>* Other names: digital examination;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Cervical Shortening | Cervix 1 was measured at the sagittal plane of cervix from external to the internal os. Two days later cervix 2 was measured the same way. The cervical shortening was calculated from subtracting cervix 1 from cervix 2. | 2days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The Duration of Latency Until Labor | The period (in days) from the last cervical measurement to the start of second phase of labor. | 15 days |
