Abstract EN
Background & Objective: Most of Syrian pregnant women do not remember their LMP exactly, so that if there is another correct way (like CRL measurement by ultrasound), It may improve the obstetric management in clinical practice.
To compares between regular last menstrual period (LMP) and ultrasonographic crown–rump length (CRL) measurements in predicting the delivery dates (EDD) in a Syrian population.
Materials & Methods: This was a prospective descriptive study of women with a normal spontaneously conceived viable singleton pregnancy, a regular menstrual cycles, and spontaneous onset of labor at term.
The LMP was considered certain in all cases.
We used ultrasound to scan 101 fetuses (72 Healthy women) at 6 6 -126 weeks.
The CRL of each fetus was measured three times, the mean of which was used to derive the best-fit regression model for estimation of gestational age in relation to CRL.
Results: The best-fit equation for the estimate of delivery date Yi Ù from CRL (in mm) was: Yi Ù =229.62 - 1.02(CRL)i + 0.0044(CRL)2 i .The mean of true gestational age at Delivery by LMP and that estimated by CRL was 272.8 ± 7.4, 272.8 ± 4.5 days, respectively.
The Median was 273, 272.7 days respectively.
The Std.Error & Std.Deviation was (0.7, 7.4) & (0.4, 4.5) days respectively.
The Std.Deviation from true Delivery dates in estimations based on LMP & CRL was 7.4 & 7.6 days respectively.
the range of error of EDD estimated by CRL was (-17&15) days .The percentages of women in whom the EDD by LMP within 3 days (±3days), 7 days (±7days), & 14 days (±14 days) of the true date of delivery were 32.7%, 51.5%, &77.2% respectively.
The correspondent percentages for CRL were 26.7%, 66.3%, & 96% respectively.
There was statistically important difference between the two methods (CRL is more accurate: Z= 8.3, P<0.001), but it was of little clinical importance.
The LMP gave later estimates, while CRL gave earlier estimates from true Delivery dates.
Conclusions: in spite of there is significant difference (P<0.001) between CRL measurements and LMP in predicting the delivery date, but these were small clinically, and CRL was more accurate.
This is of clinical importance, especially in women who forget the exact LMP, and therefore we can rely on CRL measurements
