Effects of intravenous hydration with hypotonic saline in oligohydramnios

Background: The amniotic fluid encloses and protects the fetus within the amniotic cavity in uterus. Amniotic fluid allows room for fetal growth, movement and development. The abnormal amniotic fluid either high or low volumes helps to diagnose the reduced fetal outcomes. This fluid is an important predictive tool for assessing the development of pregnancy.Methods: The present study is done to assess the effectiveness of intravenous (IV) hypotonic saline fluid maternal hydration on oligohydramnios. This study was conducted in department of obstetrics and gynecology, CHRI for 18 months. About 30 participants of third trimester with amniotic fluid index (AFI)<8 cm with the gestational age of 34-40 weeks were included. The study was done on pregnant mothers with AFI<8 cm and gestational age of 34-40 weeks. Measurement of AFI was done for all participants. The patients received 2 liters of hypotonic saline fluid over 4 hours. AFI was measured again 24 hours after baseline measurement. Treatment with IV infusion of hypotonic saline fluid is resulted in better increase in AFI in oligohydramnios.Results: After hypotonic saline infusion, the patient抯 AFI level was 7.14�31 with the p=0.000*** and it was statistically significant.Conclusions: The blood parameters and the electrolytes showed no notable changes before and after the infusion of hypotonic saline with regular antenatal visits, oligohydramnios can be detected early by clinical examination and routine ultrasonography and the proper treatment will help in preventing the complications of oligohydramnios.
