Lamicel is a synthetic osmotic cervical dilator currently used as a method of cervical dilation in first- and second-trimester pregnancy termination. It works by extracting fluid from the cervical tissue and softening the cervix. This study evaluated its effectiveness in nonelective medical induction of labor in high-risk patients. Forty inpatients who, for medical and obstetric reasons, required delivery within the next 24-48 hours were studied. Patients were evaluated to make certain that a 12- to 24-hour delay was safe for mother and child. The evening prior to the day of induction, a pelvic examination determined the Bishop score, and bacterial cultures were obtained from the endocervix. As many Lamicels as possible (usually one to three) were then placed in the endocervix without rupturing the membranes. The next morning the devices were removed, a repeat Bishop score obtained, amniotomy performed, internal monitors placed and oxytocin infusion initiated. Data were collected for preinsertion and postinsertion Bishop scores, induction-delivery times, duration of ruptured membranes, and cesarean and vaginal birth rates. Maternal and neonatal infectious morbidity was determined. A comparison group of patients with premature rupture of the membranes was selected. From data studied at our institution, patients were matched for parity and duration of labor (not significantly different from the Lamicel group). The study revealed that Lamicel can be an effective means of ripening the cervix for induction of labor.
