Purpose

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.

Arm Groups

ArmDescriptionAssigned Intervention
Experimental
Transcervical single-balloon catheter group
Participants randomized to this arm will have cervical dilation done using a transcervical single-balloon catheter.
  • Device: Transcervical single-balloon catheter
    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.
    Other names:
    • Foley catheter
Active Comparator
Osmotic dilators group
Participants randomized to this arm will have cervical dilation done using osmotic dilators.
  • Device: Synthetic osmotic dilators
    Dilators will be maintained in the cervix between 3-4 hours, during which each dilator rod will swell several times its initial dried diameter.
    Other names:
    • Dilapan-S, seaweed laminaria
