Participant Flow

Women were recruited for the study at the Women's Options Center at San Francisco General Hospital (SFGH) between October 2008 and February 2010. SFGH is San Francisco's county hospital and serves a diverse and mostly uninsured population.

Of 72 eligible and enrolled participants, 3 did not receive an abortion (2 in the Same-day Dilapan-S group, and 1 in the Overnight laminaria group).

Measure
Laminaria
laminaria placed for cervical dilation; usual standard of care in study clinic. The number of laminaria placed was calculated based on a predetermined formula: weeks gestational age minus ten.
Dilapan-S
For patients between 14 0/7 and 15 6/7 weeks' gestation on the day of the abortion, 2-3 Dilapan-S were inserted. For patients between 16 0/7 and 18 0/7 weeks' gestation, 2-5 Dilapan-S were inserted. One medium laminaria was placed along with the Dilapan-S because of the theory that the laminaria would facilitate the removal of Dilapan-S before the abortion. Patients then waited four to six hours for their abortion.

PRIMARY outcome

Timeframe: Day of procedure

Population: All patients who received a surgical abortion procedure were analyzed. Since three patients did not actually obtain an abortion within the study timeframe, we could not analyze their data, thus the analysis was per protocol.

SECONDARY outcome

Timeframe: Day of procedure

Population: All patients who received a surgical abortion procedure were analyzed. Since three patients did not actually obtain an abortion within the study timeframe, we could not analyze their data, thus the analysis was per protocol.

Any complications, or mechanical dilation required, for early second-trimester surgical abortions performed after cervical preparation with same-day Dilapan versus those performed after cervical preparation with overnight laminaria
