Brief Summary
This study will examine the effects of various formulations of progesterone on uterine electromyographic (EMG) activity in pregnant patients in premature labor to determine if progesterone will suppress uterine electrical activity and which formulation may be best for inhibition of uterine activity. Patients will be monitored prior to treatment and following treatment (every 2 to 4 hours) with one of three different formulations of progesterone for up to two days. Patients will continue to be observed until they deliver. Comparisons will be for uterine EMG activity from before treatment to that following treatments at 2, 4, 8, 12 24 and 48 hours and times of delivery after treatments (hours or days following treatments). Comparisons between mean values for EMG activity between the various treatments at the various times will also be made.

Outcome Measures
Primary Outcomes (1)
Inhibition of uterine electromyographic (EMG) activity by various formulations of progesterone.
Uterine electrical activity will be recorded (for 30 minutes at each time point) from the abdominal surface of pregnant patients before (30 minutes before treatment) and following treatment (at 2, 4, 8, 12, 24 and up to 48 hours) with either vehicles or progesterone treatments to evaluate if the treatments reduce EMG activity and therefore may be potential candidates for possible interventions for treating a preterm labor.
EMG will be measured at various times including 0 time pretreatment and up to 48 hours after treatments
Secondary Outcomes (1)
Effects of progesterone on uterine EMG activity and preterm birth
Various times after treatments up to 16 weeks to determine when the patients deliver
Study Arms (3)
Vaginal progesterone
EXPERIMENTALvaginal 150 mg micronized progesterone cream delivered via a vaginal applicator; dosed daily (Prochieve, Columbia Laboratories)
Topical progesterone
EXPERIMENTALtopical 150 mg micronized progesterone gel applied to abdomen via a novel applicator; dosed daily
Intramuscular progesterone
EXPERIMENTALinjected IM (upper arm or thigh via syringe) 50mg/day micronized progesterone (Watson Pharmaceuticals)
Interventions
Vaginal progesterone formulation (150 mg micronized progesterone daily)
Progesterone will be applied daily (150 mg micronized progesterone)by topical application
Preterm labor patients will be injected IM with micronized progesterone (50 mg/day).
Eligibility Criteria
You may qualify if:
- Healthy patients in preterm labor between 24 to 34 weeks of gestation presenting to St. Joseph's Hospital and Medical Center.
- Preterm labor is defined as at least 6 contractions in 60 minutes with a cervix either dilated to 2 centimeters or effaced to 80% and a cervical length measured by ultrasound of less than 3 centimeters, and a positive fetal fibronectin.
- Maternal ages will be within 17 to 40 year-old range.
You may not qualify if:
- Patients with preterm premature rupture of membranes (PPROM) will be excluded from the study, due to possibility of ascending infection, as will those patients with suspected chorioamnionitis.
- Patients with medical conditions that contraindicate tocolysis, such as non-reassuring fetal heart tracings, will also be excluded.
