Azithromycin Before Induction
- Registration Number
- NCT06543290
- Lead Sponsor
- Arrowhead Regional Medical Center
- Brief Summary
This is a double blinded randomized control trial involving administration of 2 grams prophylactic azithromycin in third trimester patients undergoing induction of labor at our institution to demonstrate reduction in maternal and neonatal infection.
- Detailed Description
Induction rates have more than tripled in the last quarter century, and even more in the past five years in light of evidence that the 39th week is the optimal gestational age for birth. Inductions are one of the most commonly performed medical procedures, and may span several days. One of the complications associated with induction include maternal infection, which includes chorioamnionitis, endometritis, pyelonephritis, neonatal infection, perineal and cesarean wound infections. There are many well-known risk factors for these infections that include longer duration of rupture of membrane, prolonged labor, nulliparity, internal monitoring, multiple vaginal examinations and several others. Well-established guidelines are available for treating infection once diagnosed, however the role of antibiotic prophylaxis to prevent infection in patients undergoing induction of labor is less clear. In this study, we propose that administration of 2 grams oral azithromycin prior to the start of induction of labor will decrease rates of intrapartum and postpartum infections. Azithromycin is the ideal antibiotic to study in this trial since it is long acting, inexpensive, well tolerated, and has proven benefits in prior studies for prevention of obstetrical infection in cesarean deliveries and spontaneous labor. This is a double blinded randomized control trial involving administration of 2 grams prophylactic azithromycin in third trimester patients undergoing induction of labor at our institution to demonstrate reduction in maternal and neonatal infection. Decreasing rates of infection will improve both maternal and neonatal outcomes as well as decrease hospital length of stay and associated costs.
