Antibiotics and Rupture of Water Bag During Pregnancy

Latency Antibiotics in Previable PPROM, 18 0/7- 22 6/7 WGA

This study is a non-blinded, prospective, randomized controlled trial designed to compare the effect of outpatient oral antibiotics (i.e., amoxicillin and azithromycin) on the length of time (days) that pregnancy continues after a patient's water bag has ruptured prematurely. If a patient has been diagnosed with rupture of their water bag between 18 0/7 weeks and 22 6/7 weeks and there are no other associated complications with the pregnancy, the patient is eligible for initial consideration for this study. Patients will be admitted to the hospital for a 24-hour monitoring period. If the patient remains without further complications during this monitoring period, the patient will be eligible for enrollment. If enrollment is desired, the patient will be randomly assigned to receive either antibiotics (treatment arm of the study) or no antibiotics (control arm of the study). The treatment arm will receive an outpatient, 7-day course of oral antibiotics (azithromycin and amoxicillin) with the first dose given in the hospital to ensure no side effects. The control arm will not receive outpatient antibiotics. Both groups will have weekly, office follow-up visits with high-risk pregnancy specialists to ensure no further complications. Both groups will be admitted to the hospital if the patients reach 23 0/7 weeks without complications. At this time the patients will receive all medications and therapies recommended by the governing board of OBGYNs. Subjects of both groups will also be admitted before 23 0/7 weeks if further complications noted either at their clinic follow up visits or anytime outside of the hospital. The duration of time that the patient remains pregnant after breaking of the water bag will be compared in each group. The investigators will also see if there is a difference in the number of patients able to reach 23 0/7 weeks between each group (treatment versus control).
