| Popis: | Several studies have highlighted the negative impact of maternal obesity on ultrasound accuracy for fetal weight estimation (EFW). However, the evidence is conflicting. We aimed in our study to find if the ultrasound accuracy for EFW would differ or decrease in obese and morbid obesity classes. We also studied the mode of delivery within the same cohort.It is a retrospective study of obese patients with recorded BMI ≥30 kg/mTotal 106 cases fulfilled our criteria. Class I and II as the first group (n = 53). Class III as the second group (n = 53). Maternal and birth characteristics were similar. The Pearson correlation coefficient equal 1 in both groups. The overall mean absolute difference (MAD) in grams of the whole obese cohort was 242 ± 213. The MAD was 242 ± 202 and 242 ± 226 g for the first and second group, respectively (p = 1.0). The overall mean absolute percentage error (MAPE) in this obese cohort was 8%. The MAPE for the first and second group, respectively were 8 and 7% (p = 0.4). The overall rate of cesarean delivery was 60% (64/106) with no differences between the obese and morbid obese BMI classes. Sixty-six percentage (42/64) of these cesarean cases was for repeat cesarean section.Despite what has been previously reported about the negative impact of maternal obesity on EFW accuracy, we could not demonstrate this relationship in our obese cohort (MAPE10%). In addition, we could not illustrate a significant difference in ultrasound accuracy across various obesity classes. However, we found a significantly increased rate of delivery by repeated cesarean section in this obese cohort. |
