Abstract:   (76 Views)
Objective: This study was designed to determine the relationship between the ratio of fetal lung volume to head circumference and amniotic fluid index (AFI) in the third trimester of pregnancy.
Methods: In this prospective study, low-risk pregnant women in the third trimester of pregnancy were included. Fetal lung volume was determined using lung to head ratio (LHR) for the right and left lungs separately. Also, the AFI was determined. Pearson correlation coefficient between LHR for the right and left lungs and AFI was calculated.
Results: Overall, 112 pregnant women were included in the study. The means (standard deviation [SD]) of fetal O/E RLHR (Observed/Expected Right LHR) and O/E LLHR (Observed/Expected Left LHR) were 113.9 ± 0.36 and 97.13 ± 27.87, respectively. The mean (SD) of AFI was 12.5 centimeter (4.96). Pearson correlation coefficient did not show a significant relationship between AFI and the left and right LHR (p> 0.05). However, a significant relationship was observed between O/E RLHR and abdominal circumference (AC) % (P = 0.02, r = 0.2), gestational age (P = 0.21, r = 0.27) and fetal weight (P <0.001, r = 0.27). There was a positive correlation between the number of days the infant was admitted to the neonatal intensive care unit (NICU) and the volume of the right lung of the fetus (P = 0.03, r = -0.2). No correlation was observed between fetal parameters and the volume of the left lung of the fetus.
Conclusion: The results of this study showed that AFI in the third trimester of pregnancy was not significantly correlated with LHR.
