Dilapan Versus Laminaria

Same-day Dilapan Versus Overnight Laminaria for Cervical Preparation for Early Second-trimester Surgical Abortion

This is a randomized, blinded clinical trial comparing overnight laminaria versus same-day Dilapan for cervical preparation for surgical abortions occurring between fourteen and eighteen weeks gestation. Comparisons will be made between procedure time, need for additional dilation, occurrence of complications, and patient and provider satisfaction.

Hypothesis:

Cervical preparation for surgical abortion, between fourteen and eighteen weeks gestation, with same-day Dilapan is non-inferior to cervical preparation with overnight laminaria within a five-minute difference.

Primary objective:

Determine differences in procedure times

Secondary objectives:

Examine complications, and need for additional dilation between early second-trimester surgical abortions performed after cervical preparation with same-day Dilapan versus those performed after cervical preparation with overnight laminaria

Inclusion Criteria:

• Pregnancy between fourteen and eighteen weeks gestation
• Request for elective abortion and certainty of decision to proceed

Exclusion Criteria:

• Incarceration
• Minor status (women younger than eighteen years)
• Allergy to Dilapan or laminaria
• Inability to speak and understand Spanish or English
