STUDY ON THE PREVALENCE, CLINICAL AND PARACLINICAL CHARACTERISTICS AND PREGNANCY OUTCOMES IN PREGNANT WOMEN WITH OLIGOHYDRAMNIOS AT DONG NAI 2 HOSPITAL IN 2025
Main Article Content
Abstract
Background: Abnormalities of amniotic fluid volume, including both polyhydramnios and oligohydramnios, may increase maternal and perinatal morbidity and mortality. Among these, oligohydramnios is a significant risk factor that directly affects fetal development and contributes to a higher likelihood of labor complications or the need for cesarean delivery. Oligohydramnios is defined as a reduction in amniotic fluid volume relative to gestational age.
Objectives: To determine the prevalence, clinical and paraclinical characteristics, causes of oligohydramnios, and to evaluate pregnancy outcomes in women with oligohydramnios at Dong Nai 2 Hospital from 2025 to 2026.
Materials and Methods: A cross-sectional descriptive study was conducted on 650 pregnant women, including 77 cases of oligohydramnios.
Results: The mean maternal age was 29.25 ± 5 years, with 82.5% aged 20 to under 35 years. Primigravida accounted for 62.92%, and 62.31% had no previous deliveries. The average pre-pregnancy weight was 50 kg, and 74.46% had appropriate gestational weight gain. Occiput anterior presentation was predominant (92%). The mean fundal height was 29.45 ± 2.6 cm, and the mean abdominal circumference was 92.6 ± 6.0 cm. The average fetal heart rate was 141 ± 5.13 beats per minute. Cephalic presentation accounted for 95%, and the mean amniotic fluid index was 3.76 ± 1.24 cm. The mean biparietal diameter was 8.88 ± 0.52 cm, and the mean femur length was 6.93 ± 0.39 cm. Cesarean section was the most common mode of delivery in oligohydramnios cases (90%). After delivery, 89.27% had normal amniotic fluid characteristics, and the mean neonatal birth weight was 2,972.5 ± 500.17 grams. A favorable Apgar score at birth was observed in 99.37% of newborns.
Conclusion: Most cases of oligohydramnios presented with clinical and paraclinical findings within normal limits; however, the primary mode of management was cesarean section. No cases underwent induction of labor with successful vaginal delivery.
