Antibiotic Prophylaxis to Prevent Obesity-Related Induction Complications in Nulliparae at Term
United States186 participantsStarted 2018-12-12
Plain-language summary
Obesity increases the risk of pregnancy complications, including among others puerperal infections and cesarean delivery, and risk rises with increasing body mass index (BMI). Class III obesity is an indication for delivery by 39 weeks, and these patients have a high rate of labor induction. In nulliparous women from the general population (obese and non-obese), labor induction at 39 weeks (compared to expectant management) is associated with less morbidity and a lower cesarean rate. Antibiotic prophylaxis, standard before cesarean delivery, is associated with less post-cesarean infection if azithromycin is added to the standard cefazolin. In this placebo-controlled pilot trial, investigators will estimate the parameters necessary to calculate the sample size for a planned multicenter clinical trial of prophylactic antibiotics administered at the start of labor inductions of morbidly obese nulliparous women at term.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
