Materials and Methods:
This study was conducted at two centers, 1) Women’s Hospital in Doha – Qatar and 2) the Academy Hospital in Khartoum – Sudan. However, all the procedures (transabdominal amnioinfusion) were done by the same operator who has more than 20 years of experience in invasive intrauterine procedures. The procedure was explained to the patients and verbal consent was obtained. All the patients received antibiotic prophylaxis. It was found that deepest vertical pool (DVP) of less than 3 centimeters was recorded for the entire study group, confirming the diagnosis of oligohydramnios. Prior to the procedure, all the patients were examined clinically to exclude spontaneous rupture of membrane (SROM). This was done by vaginal examination using a sterile speculum in search for liquor leaking from the cervical canal or the presence of a pool of liquor in the vagina. One patient experienced loss of fluid during the procedure which confirms SROM and was excluded from the study. Amnioinfusion was done using amniocentesis needle under direct US guidance. All the fetuses were examined in great details by a fetal medicine specialist. The examination was difficult and nonconclusive in majority of cases because of reduced liquor, high BMI and adhesion due to previous surgery (mainly caesarean section scars and liposuction).
We collected the following data: maternal age, parity, BMI, gestational age at presentation, deepest vertical pool for every patient, mode of delivery, fetal and neonatal outcome.
