Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

After preterm prelabor rupture of membranes (PPROM)\[breaking of the amniotic sac prior to 37 weeks gestation in pregnancy\], patients are recommended for inpatient admission and close monitoring for complications including preterm labor, intraamniotic infection (infection of the sac around the baby), and placental abruption (separation of the placenta from wall of the uterus). When evaluation of cervical dilation is clinically indicated, obstetricians traditionally perform sterile speculum exams due to concern for decrease in pregnancy latency (length of time between breaking the water and delivery) with sterile digital exams in retrospective studies. These studies are concerning, however, by the indications for the exams and are at risk for confounding by indication. This is a randomized, non-inferiority trial to examine if sterile digital versus speculum exams effect latency of pregnancy in patients with PPROM.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Speculum Exams

If a patient requires cervical evaluation after PPROM, their cervix will be evaluated with a sterile speculum exam. A sterile speculum with lubricating jelly will be inserted into the patient's vagina to visualize the cervix and visually estimate cervical dilation and effacement.

Digital Exams

If a patient requires cervical evaluation after PPROM, their cervix will be evaluated with a digital exam. The provider will wear sterile gloves with lubricating jelly and will palpate the cervix to assess cervical dilation, effacement, and station.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* 22 weeks 0 days gestation to 33 weeks 5 days gestation
* Clinical or laboratory confirmation of PPROM
* At least 8 hours after rupture event
* English speaking

Notably, for patients \<25 weeks, approach for enrollment will be deferred until after the patient has discussed their desires for fetal resuscitation with the care team and are at a gestational age where they would desire this resuscitation.

Exclusion Criteria

* Contraindications to digital examination
* COVID-19 positive on admission
Eligible Sex
