ORIGINAL RESEARCH
Borderline Amniotic Fluid Index and Its Relation to Fetal Intolerance of Labor A 2-Center Retrospective Cohort Study S. Lindsay Wood, MD, J. Michael Newton, MD, PhD, Li Wang, MS, Karen Lesser, MD
Objectives—To determine whether a borderline amniotic fluid index (AFI) in the third trimester is associated with an increased rate of cesarean delivery for fetal intolerance of labor, meconium-stained amniotic fluid, and intrauterine growth restriction, among other adverse perinatal outcomes. Methods—Patients with a diagnosis of a borderline AFI between January 2008 and August 2012 were identified. Antepartum, delivery, and neonatal data were collected and compared to a cohort with a normal AFI.
Received June 3, 2013, from the Department of Obstetrics and Gynecology, University of Arizona, Tucson, Arizona USA (S.L.W., K.L.); and Departments of Obstetrics and Gynecology (J.M.N.) and Biostatistics (L.W.), Vanderbilt University, Nashville, Tennessee USA. Revision requested June 25, 2013. Revised manuscript accepted for publication August 26, 2013. We thank the University of Arizona sonographers along with Pam Tankersley. The preliminary findings of this study were presented at the 2012 American Institute of Ultrasound in Medicine Annual Convention; March 29–April 1, 2012; Phoenix, Arizona.
