Objective
To compare the efficacy of Laminaria tents with Misoprostol for cervical ripening before surgical process in missed abortion.
Method
In a prospective study, 70 women with missed abortion were assigned to have either insertion of a 3 mm intracervical Laminaria tent (n = 35) or vaginal Misoprostol 400 μg (n = 35) on the day prior to suction dilation and curettage (D/C). The women were interviewed just prior to the D/C with regard to pain, vaginal bleeding, and cervical dilator preference.
Result
Cervical dilation was greater in the Laminaria group but not significantly different from that in the Misoprostol group. However, additional cervical dilation before D/C was required in more patients in the Misoprostol group (45.7 vs 14.3%, P = 0.001). Women who received Laminaria reported significantly more pain at the time of insertion (62.8% in Laminaria group vs 22.8% in Misoprostol group) compared with women who received Misoprostol. Conversely, Misoprostol was associated with more nausea, vomiting, diarrhea and vaginal bleeding.
Conclusions
Laminaria tents are more effective cervical dilators than vaginal Misoprostol when inserted the day prior to suction D and C. Vaginal Misoprostol insertion is more comfortable, although it is associated with an increased risk of vaginal bleeding.
