Brief Summary
This is a noninferiority randomized control trial of two cervical preparation methods prior to same-day Dilation \& Evacuation (D\&E). Cervical preparation is a process that softens and dilates the cervix prior to a procedure. The primary objective is to evidence noninferiority of cervical preparation using a single-balloon catheter method when compared to a group receiving osmotic dilators, specifically in D\&E operative time. Secondary objectives will compare the two methods for adequate dilation, ability to complete the operation in the same day, participant pain, satisfaction and safety.

Outcome Measures
Primary Outcomes (1)
Dilation & Evacuation (D&E) Operative time
the total duration in D\&E operative time measured in minutes. Operative start time will be marked as the time that the speculum is inserted for the first time. Operative end time will be marked as the time that the speculum is removed at the end of the case.
at end of procedure about 20 minutes
Secondary Outcomes (5)
Participant preoperative pain
every hour until procedure, on average 3 hours
Participant satisfaction
after dilation, on average 3 hours
Cervical dilation
beginning of procedure, on average 3 hours
Number of participants with adequate cervical dilation
beginning of procedure, on average 3 hours
Number of participants with surgery completed in the same day
12 months
Study Arms (2)
Transcervical single-balloon catheter group
EXPERIMENTALParticipants randomized to this arm will have cervical dilation done using a transcervical single-balloon catheter.
Osmotic dilators group
ACTIVE COMPARATORParticipants randomized to this arm will have cervical dilation done using osmotic dilators.
Interventions
A single-balloon (Foley) catheter will be placed through the cervix and filled to 30cc of water or saline. The balloon will remain in the participant until their procedure, usually 3-4 hours, or earlier if it falls out on its own.
Dilators will be maintained in the cervix between 3-4 hours, during which each dilator rod will swell several times its initial dried diameter.
Eligibility Criteria
You may qualify if:
- Between 16 weeks 0 days - 18 weeks 6 days gestational age who are pursuing termination, based on reliable gestational age (defined as ultrasonography performed by a clinical provider, or a certain last menstrual period)

- English- or Spanish-speaking
- Singleton intrauterine pregnancy
You may not qualify if:
- Allergy to betadine, aquacryl hydrogel, latex-free silicone single-balloon catheter, synthetic or natural osmotic dilators
- Fetal demise or known fetal anomaly
- BMI \>45
- Incarceration or other inability to give informed consent
- Decide to undergo cervical preparation overnight prior to next-day D\&E
