Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The termination of abortion is an important issue that has many controversies. The most common time of serious abortion-related complications is the second trimester. Missed abortion is one of the most common indications of termination of pregnancy in the second trimester. Misoprostol and mifepristone are effective drugs for induction of abortion but these drugs are now expensive, and non-available in many developing countries.

The effectiveness of Foley's catheter balloon on cervical ripping for mid-trimester pregnancy termination has been proved before. It can effectually shorten the time of the expulsion of the fetus. Amniotomy defines as an artificial rupture of the membranes; it is an ordinary obstetric practice used mainly in the induction of labor, with good results and less morbidity. The obstetricians used to combine amniotomy with other methods such as prostaglandins or oxytocin to induce labor in a woman with an unfavorable cervix.

Despite plenty of studies that investigated the role of amniotomy for induction of labor but the studies which addressed the role of amniotomy in the induction of second-trimester abortion are very scarce in the literature.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Amniotomy group

Amniotomy will be performed by toothed forceps. The handle of the device will be held with one hand outside the vagina while 2 fingers of the opposite hand will be placed in the vagina to guide the tip.

Group Type OTHER

Foley catheter balloon

Intervention Type DEVICE

A Cusco speculum will be placed and a 16F Foley catheter will be inserted into the cervix using ring forceps. Then the balloon will be inflated with 40 ml of saline and it will be pulled out to ensure the balloon covered the internal os of the cervix

Amniotomy

Intervention Type PROCEDURE

Amniotomy will be performed by toothed forceps. The handle of the device will be held with one hand outside the vagina while 2 fingers of the opposite hand will be placed in the vagina to guide the tip. Care should be taken to protect maternal vaginal tissues from the forceps. Once the forceps reach the amniotic sac, the tip is pushed up against the sac with the index or middle finger of the internal hand to pierce the membranes. The nature of amniotic fluid will be checked.

Oxytocin

Intervention Type DRUG

The intravenous oxytocin infusion will be administered as 10 IU oxytocin/ 500 ml glucose/ 30 mIU/minute were every 6 hours till complete abortion occurs.

No-amniotomy group

No-amniotomy will be done

Group Type OTHER

Foley catheter balloon

Intervention Type DEVICE

A Cusco speculum will be placed and a 16F Foley catheter will be inserted into the cervix using ring forceps. Then the balloon will be inflated with 40 ml of saline and it will be pulled out to ensure the balloon covered the internal os of the cervix

Oxytocin

Intervention Type DRUG

The intravenous oxytocin infusion will be administered as 10 IU oxytocin/ 500 ml glucose/ 30 mIU/minute were every 6 hours till complete abortion occurs.
