Abstract
INTRODUCTUION: Gestational age is the age of the unborn baby. The accurate knowledge of gestational age is the key for appropriate interpretation of antenatal test and effective planning for intervention or treatments. OBJECTIVE: To assess the accuracy of estimating gestational age by symphysis fundal height (SFH) , last normal menstrual period (LNMP) and Ultrasound (US )measurements during third trimester pregnancy. METHODS AND MATERIALS: Hospital based cross sectional study was carried out from June 9, 2016 – October 20, 2016 in radiology unit of Gandhi Memorial Hospital. Estimated gestational age was taken from 182 women of third trimester by LNMP, SFH and four parameter of ultrasound; femur length (FL), biparietal diameter (BPD), head circumference (HC) and abdominal circumference (AC). Data was analyzed using SPSS version 21 computer program. The mean difference among different methods was tested for significance using paired t-test. Correlations among measurements were tested. Pvalues less than 0.05 were taken as statistically significant. RESULT: The mean gestational age of pregnancy by recalled LNMP was 36.35 weeks with standard deviation of 3.35 weeks. The mean gestational age by the parameters of ultrasound scan done by FL was 36.64 weeks, BPD was 36.57 weeks, HC was 34.01 weeks, and AC was 33.94 weeks. The mean gestational age by SFH measurement was 34.88 weeks. The mean gestational age estimated by all three methods; SFH, LNMP and US measurements had statistically significant difference (p ≤ 0.05). SFH estimate had only 0.39 week difference from estimate by composite of FL, BPD, HC and AC. FL and BPD had stronger correlation than HC and AC with composite US measurements. SFH had stronger correlation with all ultrasound measurement than LNMP. CONCLUSION: SFH was better method to estimate gestational age than LNMP. The BPD and FL were more accurate measurement followed by AC and HC during third trimester in comparison with composite US measurement
