ABSTRACT

Objective: To determine the normal reference range of femur length, bi-parietal diameter and abdominal circumference in duration of 2nd and 3rd trimester of pregnancy in local population.

Study Design: A cross-sectional analytical study.

Place and Duration of Study: This study was conducted at the Department of Anatomy / Community Medicine, at Bahawal Victoria Hospital, Bahawalpur from July 2020 to July 2021.

Materials and Methods: After taking approval from Institutional ethical review committee. All the pregnant women during 2nd and 3rd trimester of pregnancy with no known medical conditions, singleton fetus were included in the study. There were total 1,424 female participants in the study. Pelvic ultrasound was performed for evaluation of biparietal diameter, femur length and abdominal circumference by the consultant radiologist. Out of 1424, 484 were in 2nd trimester while, 940 were in 3rd trimester. For continuous variables, data was presented as mean standard deviation. Reported percentiles were 5th, 50th, 75th and 90th. SPSS version 25.0 was used for data analysis.

Results: The range of femur length was from 16 mm to 53 mm and 55mm to 79 mm in 2nd and 3rd trimester respectively. The range of fetal mean biparietal diameter (BPD) was 14-71mm and 74-98mm in 2nd and 3rd trimester respectively. The mean abdominal circumference (AC) ranged from 86-365mm at 14-41 weeks of gestation. Conclusions: The study provided percentiles and normal reference range of femur length, bi-parietal diameter and abdominal circumference in duration of 2nd and 3rd trimester of pregnancy. 

Conclusion: In our results we have given percentiles and normal reference line of femur length, abdominal circumference and biparietal diameter in 2nd and 3rd trimester of pregnancy in local population
