Prediction of gestational age by ultrasonic measurement of the Biparietal diameter in third trimester
Journal Title: Medpulse International Journal of Gynaecology - Year 2019, Vol 9, Issue 2
Abstract
Background: Rapid and accurate determination of gestational age (GA) may be vital to the appropriate care of the pregnant patient and improve obstetric care through allowing the optimal timing of necessary interventions and the avoidance of unnecessary ones. Ultrasound scans are considered to be the most cost-effective, accurate and safe method for measurement of various fetal parts in pregnant women. Objectives: To study the prediction of Gestational Age by Ultrasonic Measurement of the Biparietal Diameter in Third Trimester. Materials and Method: In the present study total 100 pregnant female attending antenatal clinic of the study institute in third trimester were enrolled. Detailed demographic profile including age, address etc was obtained. Detailed history regarding the exact knowledge of her LMP, cycle regularity and duration of cycle was taken. All patients then underwent detailed examination i.e. general and systematic examination. The gestational age at time of scanning was confirmed by LMP, and abdominal examination. All the women in the study underwent ultrasonoghraphy. The ultrasound was done by a single operator to avoid bias in observations. All the fetal parameters were assessed and special attention was given to the Biparital diameter. The collected data was entered in Microsoft excel. Primary analysis was conducted by using Epi Info statistical software. Results: Majority of the patients (38%) belonged to age group 20- 25 years followed by 36 patients in 25-30 years. Gestational age was calculated according to the LMP and it was observed that majority of the patients were of 35 weeks gestation (14%) followed by 30 weeks (12%) and minimum were of 40 weeks gestation. The mean gestational age was 33.53±3.368 weeks. The gestational age was calculated by using BPD on ultrasonoghraphy and it was seen that majority of the women were of 38 weeks of gestational age (16%) followed by 33 weeks of gestation (13%) with mean gestational age of35.87±2.96 weeks.Similarity of GA in LMP with BDP was observed in 13 patients. The Correlation coefficient between GA by LMP and GA by BDP was 0.9268 with P-Value <0.05. Thus there was significant correlation between GA by LMP and BDP. Conclusion: The gestational age estimated from Biparital diameter was correlated with the gestational age calculated from the LMP with Correlation coefficient of 0.9268 with P-Value <0.05.Thus we conclude that the Biparital diameter can be useful in evaluation of Assessment of Gestational Age in Third Trimester and the findings
