About

Primary objective: To study the difference in dilation and evacuation (D&E) procedure time following overnight cervical preparation with laminaria or Dilapan-S™. The investigators hypothesize procedure time will be less with Dilapan-S™.

Secondary objectives: To compare the use of laminaria and Dilapan-S™ for differences in: (1) initial cervical dilation before D&E; (2) need for mechanical dilation to accomplish D&E and ease of dilation if required; (3) number of osmotic dilators placed; (4) ability to complete the D&E procedure without further cervical preparation; (5) complications; (6) pain and other side effects; (7) patient acceptability; and (8) provider acceptability.

Full description

One hundred eighty women were randomized evenly across treatment arms, stratified by gestational age groups of 18 0/7-20 6/7 (n= 91) and 21 0/7-24 0/7 (n=87). The analytic sample N=173 (laminaria=86, Dilapan=87); 2 cases were removed for post-randomization exclusion and 5 for missing data on one or more outcome variables. Demographic information and results for the primary outcome of procedure time are reported below in tabular form in the results section.
