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.
