Background: Amniotic fluid has many important functions and is regulated by multiple factors. It is integral to fetal development, including fetal pulmonary, gastrointestinal, and musculoskeletal maturation. It also acts to cushion the fetus from trauma. It is also believed to be sterile and possesses bacteriostatic properties. Amniotic fluid is regulated by fetal swallowing, fetal urine production, lung secretions, and intramembranous absorption. Amniotic fluid abnormalities (either increased or decreased fluid) are due to dysregulation of these processes from maternal or fetal disease. Normal amniotic fluid volume has been extensively studied using direct measurement, dye dilution methods, and ultrasound estimation. Materials and methods: The present study was conducted in the Department of Obstetrics and Gynecology, Arundathi Hospital over a period of 1 year. This study subjects consisted of registered antenatal patients at term gestation with single live fetus in cephalic presentation. The study group subjects constituted registered 90 antenatal cases presented at gestational age above 37 weeks. The mothers during their first visit were included for detailed history, clinical examination and blood investigations as follows. Detailed case history including age / parity / menstrual history / obstetric history/past and family history were taken. Detailed general and systemic examination of the patient was done. Result: The study was done on 90 antenatal patients with oligohydramnios. The mean age group of the study participants was 28.39±6.49 years. Majority (50%) of them were primigravida and most of them (44%) belonged to the age group of 26 to 30 years. 41(82%) patients required an emergency LSCS and 35 (38.9%) of the new-born required an extra care and were admitted in NICU. Gestational age, birth weight and abnormal doppler study were found to have an association with the perinatal outcome. The present study revealed that children with increased birth weight and gestational age had a favourable perinatal outcome. Those with an abnormal doppler study had an unfavourable perinatal outcome. Other factors like age of the mother, parity, mode of delivery and AFI did not have any association with perinatal outcome. Perinatal mortality in the present study was 8.9%. Conclusion: In conclusion, due to such adverse outcomes mentioned in patients with borderline AFI and because there is no sufficient evidence and specific decision about delivery based on a borderline AFI, there should be a close observation and antepartum surveillance for them. Also, further studies with prospective design are needed. [ABSTRACT FROM AUTHOR] |
