Plain Language Summary

Simplified for easier understanding

This study evaluates the use of ultrasound-guided manual vacuum aspiration (USG-MVA) for treating miscarriage. USG-MVA is a gentle suction procedure done under ultrasound guidance to remove pregnancy tissue — an alternative to medication or waiting for natural passage. You may be eligible if: - You are a woman aged 18 or older - You have had a miscarriage in the first trimester (up to 12 weeks) or an incomplete miscarriage with less than 5 cm of retained tissue - You are hemodynamically stable (blood pressure and heart rate are stable) - You can tolerate a speculum examination You may NOT be eligible if: - You have cervical stenosis (narrowing of the cervical canal) - Your uterus is enlarged to 12 weeks size or more due to fibroids - You have a known uterine abnormality - You have a bleeding disorder - There is concern for active pelvic infection - You cannot tolerate a pelvic examination - You have a known allergy to misoprostol or similar medications Talk to your doctor to see if this trial is right for you.

Interventions

PROCEDUREultrasound-guided manual vacuum aspiration (USG- MVA)

USG-MVA was carried out as an outpatient day procedure. Women was given a 400μg oral misoprostol tablet 2-3 hours before the procedure. All patients will be given 500mg naproxen orally an hour before the procedure. During the USG-MVA, all the women were placed in the lithotomy position and aseptically dressed. Speculum was performed to visualize the cervix with PCB performed. USG-MVA was performed using a 60ml charged syringe with a flexible curetteattached to it. Transabdominal USG during MVA was performed. During the procedure, local lidocaine gelwas applied to the cervical canal and over the end of the MVA catheter tip during the insertion.The USG-MVA was stopped as soon as USG confirmed that the uterine cavity was empty, defined as a thin endometrial lining with no evidence of retained products of conception.
