title: [Analysis of 196 cases of trial of labor with borderline oligohydramnios assessed by ultrasound].
abstract: OBJECTIVE
  To determine the effect of borderline oligohydramnios on perinatal outcome.
  
  
  METHODS
  Patients admitted for delivery had an amniotic fluid index (AFI) assessment. Color Doppler was used to examine the systolic/diastolic ratio of the blood flow velocity in fetal umbilical arteries. Normal amniotic fluid volume was defined as an AFI of 8.1-18 cm (n = 200), and borderline oligohydramnios as 5.1-8.0 cm (n = 196). The two groups were compared on perinatal outcomes as all of the patients had trial of labor.
  
  
  RESULTS
  There was no difference in the incidence of fetal distress and neonatal mortality between the two groups. The incidence of emergency section in borderline oligohydramnios group was significantly higher.
  
  
  CONCLUSIONS
  The patients with borderline oligohydramnios may have a trial of labor under proper intensive care.
