Study summary

The goal of this study is to compare two clinically-relevant bladder drainage techniques. This is a randomized controlled trial with a single primary outcome of time to delivery. The results will inform clinical decisions about method of catheterization during labor.

Read the detailed description

Urinary catheterization is a common practice during labor following placement of an epidural for pain control, as this form of anesthesia is known to inhibit normal bladder emptying. There is insufficient evidence to guide clinicians in selection of an indwelling catheter versus intermittent straight catheterization during the course of labor.

The goal of this randomized control trial is to compare two clinically-relevant bladder drainage techniques.

Study arms

  • Active comparator
    Indwelling foley catheter

    Insertion of an indwelling foley catheter when bladder emptying is necessary. The indwelling catheter will remain in place until the time of delivery.

    Procedure: Indwelling catheter

  • Active comparator
    Intermittent straight catheterization

    Intermittent straight catheterization will be performed as needed during labor.

    Procedure: Intermittent straight catheterization

Interventions

  • ProcedureIndwelling catheter

    Indwelling bladder catheter will remain in place until time of delivery.

  • ProcedureIntermittent straight catheterization

    intermittent straight catheterization will be performed on an as needed basis until time of delivery.

What researchers measure

Primary outcomes

  1. Time to Delivery (by Any Route)

    Time to delivery defined as IV placement to delivery of infant.

    Time frame: 1 day

Secondary outcomes

  1. Difference in Cost Between the Two Interventions

    Cost of the intermittent vs. foley catheterization procedures was measured and reported in mean dollars.

    Time frame: End of study.

Participant flow

Participants were enrolled 7/09-11/09 from the obstetric units of the Loyola University Health System hospitals. Subjects included adult women with a singleton pregnancy who presented to the Labor \& Deliver in active labor or for induction, were anticipated to have an normal spontaneous vaginal delivery (NSVD), and had an epidural.
