Oligohydramnios, or decreased amniotic fluid, is associated with morbidities (cesarean delivery [CD] for nonreassuring fetal heart rate tracing [NR FHR], low Apgar score) and mortality, even among nonanomalous fetuses. Summation of the deepest pocket measurement in 4 quadrants, called the amniotic fluid index (AFI), or measuring the single deepest pocket (SDP) in any quadrant is used to sonographically assess amniotic fluid. The AFI should be abandoned in favor of SDP because metaanalysis of 5 randomized clinical trials (RCTs), with more than 3200 women, noted that use of AFI significantly increased the likelihood of being categorized as oligohydramnios, being induced and undergoing CD for NR FHR, without concomitant improvement in neonatal outcomes. Additionally, the substantial literatur...
