Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Dilapan Group | Patients who are randomized to receive Dilapan, will have 3-5 rods of Dilapan-S® inserted in their cervix by the supervising provider, under aseptic precautions with a speculum exam, either digitally or using a sponge forceps, as per manufacturer's recommendations. The Bishop score at the time of eligibility assessment and number of rods inserted will be recorded. Dilapan will be left in cervix for 12 hours. Patients will be allowed to ambulate, shower and have light meals as long as they meet the criteria based on institutional guidelines for intermittent fetal heart monitoring. Nothing per vagina including douching and no bathing is allowed.~Dilapan: Dilapan-S® is a mechanical method for cervical ripening using rods made of a patented hydrogel Aquacryl, it is marketed in form of rods of 3 and 4 mm diameter. It is FDA approved for cervical ripening. | 86 | 134 | OG000 |
| Group 2 | Misoprostol Group | Patients who are randomized to Misoprostol group, after the baseline assessment and a reassuring cardiotocograms (CTG) monitoring for 20 minutes to a maximum of 6 doses. All subjects will have continuous fetal monitoring. A dose will be held if patient is noted to have uterine tachysystole, hyperstimulation, fetal heart tracing abnormalities or 3 or more painful uterine contractions over a period of 10 minutes (indicating onset of labor). Administration of Misoprostol will be done by the nurse assigned to the patient.~Misoprostol: 25mcg of Misoprostol will be administered orally every 2 hours (maximum of 6 doses)~Misoprostol is a prostaglandin E1 analog approved for treatment and prevention of gastric ulcers. The use of Misoprostol appears to be safe and effective for induction of labor when used in low dose. | 86 | 138 | OG001 |
