  Purpose

PKAZ is a single institution study designed to evaluate the optimal dosing parameters for azithromycin for pre-surgical cesarean prophylaxis.

Hypothesis: Pre-operative administration of azithromycin results in maternal and neonatal tissue concentrations that adequately treat microbes commonly involved in post-cesarean infections.


Condition Intervention
Endometritis
 Drug: Azithromycin

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: The Pharmacokinetics of Azithromycin Prophylaxis for Cesarean Delivery

Primary Outcome Measures:
  • Number of patients in each group that attain an adequate azithromycin concentration [ Time Frame: 48 hours after delivery ] [ Designated as safety issue: No ]
    The primary outcome of this study will be the number of patients in each group that attain an azithromycin concentration in the various maternal and fetal tissues at least equivalent to the MIC 90 for common organisms involved in post-cesarean infections.


Biospecimen Retention:   Samples Without DNA

Maternal blood, maternal adipose tissue, maternal myometrium, maternal breast milk, amniotic fluid, and fetal cord blood.
