ABSTRACT
Background– Gestational diabetes mellitus (GDM) is defined as intolerance of glucose seen during pregnancy and is associated with fetal and maternal morbidity. The aim of our study was to measure various fetal sonographic parameters such as fetal biometry, fetal liver length (FLL), amniotic fluid deepest pocket (AFDP), placental thickness, inter ventricular (IV) septum thickness, Wharton's jelly area and fetal abdominal fat thickness (FAFT) during 21-24 weeks of gestation and comparison of these parameters between Gestational diabetic and normal pregnant women. Tot Methods: al patients selected in our study were 100 in number, of which 50 had GDM and 50 were normal pregnant women. Fetal standard biometry with additional parameters were measured on transabdominal scan from 21-24 weeks. Fetal sonographic measurements and patients characteristics were measured and compared between two groups. P-value was evaluated along with mean, standard deviation, mean difference and confidence interval Patient characteristics and standard fetal Results: biometric parameters were comparable except for femur length (FL), mean femur length was significantly greater in GDM women compared to normal pregnant women (39.20 ± 0.70 vs. 38.36 ± 1.20, p = 0.001). Mean values in GDM vs. normal pregnent women were, fetal placental thickness in mm ( 42.28 ± 2.09 vs. 33.24 ± 1.70, p = 0.001), amniotic fluid maximum vertical pocket in mm (54.96 ± 1.24 vs. 44.46 ± 1.06, p = 0.001), fetal abdomen fat layer thickness in mm (3.59 ± 0.17 vs. 3.46 ± 0.15, p = 0.001), inter ventricular septum thickness in mm (3.71 ± 0.13 vs. 3.63 ± 0.16, p = 0.001), fetal liver length in mm (36.48± 1.15 vs. 31.86 ± 0.90, p = 0.001), Wharton jelly area in mm2 (115.26 ± 1.96 vs. 109.34 ± 4.81, p = 0.001), Fetal sonographic Conclusion: parameters are significantly increased in GDM women compared to normal pregnant women even before 24 weeks. Measurements of these parameters in routine practice could be used to monitor fetal growth and hence can prevent fatal complications.
