Official Title: Sildenafil Citrate Therapy for Oligohydramnios

Brief Summary: The aim of this randomized trial is to detect whether or not the use of Sildenafil citrate therapy will increase the amniotic fluid volume expressed in term of amniotic fluid index measured via ultrasound for fetuses of pregnancies complicated by oligohydramnios, and to compare the outcomes of Sildenafil-treated pregnancies with similar pregnancies that will remain Sildenafil-naïve.

Detailed Summary:

Women who will be referred to the maternity ward of both hospitals for a checkup and have the inclusion criteria will be offered admission for at least 24 hours to have complete rest aiming to increase the placental blood circulation of the uterus, which by itself can improve the amniotic fluid level. Patients will be randomly allocated into two groups according to a trial sequence determined via a computer generated random table. The trial sequence is hidden into opaque sequenced envelopes as each envelope contains an assignment for a single patient. Patients in first group will receive 2 liters of isotonic saline through intravenous infusion over a period of 4 hours using a rate of 250 ml per hour in addition to sildenafil citrate therapy (Viagra®) as 25 mg 3 times daily and the same fluid regimen will be used in control group but without sildenafil citrate treatment. During hospital course maternal monitoring will be done using maternal vital signs for early detection of any manifestations of fluid overload while fetal monitoring will be done using non-stress test and all patients less than 34 completed weeks will receive dexamethasone in a total dose of 24mg to enhance fetal lung maturity in case expedited delivery is needed. Fasting will also be recommended during fluid therapy in case any emergency interference is required then all patients will resume their usual daily diet and fluid intake. All patients will then undergo sonography after 24 hours for reassessment of amniotic fluid index and those who will show an improvement of at least 20% will be discharged home and for those who still show no results the same regimen will be repeated. Discharged patients in first group will be asked to continue sildenafil citrate therapy (Viagra®) as 25 mg 3 times daily plus a daily oral fluid intake of 2 liters while those in the control group will be asked only to have 2 liters daily oral fluid.
