Abstract
Background: The ability to quickly and accurately determine gestational age (GA) can help improve obstetric care by allowing for the timing of necessary interventions to be as early as possible and avoiding those that are not absolutely necessary. For measuring different baby parts in pregnant women, ultrasound scans are thought to be the most efficient, precise, and safe procedure.
Objective: To examine the accuracy of gestational age prediction using ultrasound to measure biparietal diameter in the third trimester.
Materials and Methods: 200 pregnant women who visited the study institute's antenatal clinic in the third trimester were included in the study. Age, address, and other specific demographic information were acquired. A thorough history was collected, including details on her LMP, cycle regularity, and cycle length. Then, each patient got a thorough checkup, which included a general and systematic examination. LMP and abdominal examination provided confirmation of the gestational age at the time of scanning. The study's female participants received ultrasonography. To prevent bias in observations, only one operator performed the ultrasonography. The Biparital diameter received particular consideration as all foetal characteristics were evaluated. Microsoft Excel was used to enter the data that was gathered. Epi Info statistical software was used for the primary analysis.
Results: The majority of the patients (38%) were in the 20–25 year age range, followed by 72 patients in the 25–30 year range. The LMP was used to calculate gestational age, and it was found that the majority of patients (14%) were 35 weeks along, followed by 30 weeks (12%), and at least 40 weeks gestation. 33.27 3.334 weeks was the average gestational age. The gestational age was determined by BPD on ultrasound, and it was discovered that the majority of the women were 38 weeks along (16%), followed by 33 weeks along (13%) with a mean gestational age of 35.44 2.48 weeks. In 26 individuals, GA in LMP was shown to be similar to BDP. With a P-Value of 0.05, the correlation coefficient between GA by LMP and GA by BDP was 0.9268. The connection between GA by LMP and BDP was therefore substantial.
Conclusion : With a correlation coefficient of 0.9268 and a P-value of 0.05, the gestational age determined by biparital diameter was correlated with the gestational age determined by the LMP. Consequently, we draw the conclusion that the Biparital diameter can be helpful in assessing the Assessment of Gestational Age in Third Trimester and the findings.
Key Words: BPD, third trimester, and age assessment using ultrasound.
