Study aim
-
Comparison of the effect of traction catheter and normal amniotic extraction (EASI) on cervical preparation in primiparous mothers candidates for termination of pregnancy
-
Design
-
This single-blind randomized clinical trial with parallel groups will be performed on 52 pregnant women. Patients are randomly divided into two groups by block randomization. In patients in EASI group, cervical catheter will be used and in cervical traction catheter group, cervical catheter will be used.
-
Settings and conduct
-
This single-blind randomized clinical trial study with parallel groups will be performed on 52 women with a gestational age of 37 weeks and older in Zanjan academic hospital. In this study, data collectors, outcome assessors, and manuscript writers will be completely unaware of the drug prescribing protocol.
-
Participants/Inclusion and exclusion criteria
-
Inclusion criteria are gestational age equal to or greater than 37 weeks (based on LMP and first trimester ultrasound), single pregnancy. Patients with a history of previous cesarean section, placenta previa, premature rupture of membranes, and people with preeclampsia will be excluded from the study.
-
Intervention groups
-
In EASI patients, 15 cc of normal saline solution is first injected into the cervical catheter balloon and then this infusion is continued at a rate of one milliliter per minute into the extraamniotic space. In the cervical traction catheter group, in the lithotomy position, the cervical catheter No. 24 passes directly throw the inner hole of the cervix and its balloon will be filled with 30 cc of sterile serum.
