ABSTRACT
OBJECTIVE: Our objective was to examine the association between sonographic estimated fetal weight (EFW) and obstetrical and neonatal outcomes in women with neonatal macrosomia. STUDY DESIGN: This study, conducted at a tertiary university-affiliated hospital from 2017 to 2021, compared obstetrical and neonatal outcomes between two groups of women who delivered macrosomic newborns (actual birthweight ≥ 4,000 g): (1) those with EFW ≥ 3,800 g (suspected impending macrosomia) and (2) those with EFW < 3,800 g (unsuspected impending macrosomia). RESULTS: During the study period, 854 women with neonatal macrosomia attempted vaginal delivery. Only 9.2% had a sonographic EFW ≥ 4,000 g. Among women with EFW ≥ 3,800 g (n = 317) compared with EFW < 3,800 g (n = 537), the cesarean delivery (CD) rate was higher (17.0 vs. 10.5%, p = 0.004) and the operative delivery rate was lower (3.2 vs. 0.6%, p = 0.015). Among primiparous women, the CD rate was higher among those with EFW ≥ 3,800 versus <3,800 g (37.3 vs. 23.2%, p = 0.033). EFW ≥3,800 g was associated with CD, regardless of predelivery body mass index, parity, diabetes mellitus, maximal fetal weight at previous deliveries, actual birthweight, and labor induction (p = 0.014). EFW ≥ 3,800 g and diabetes mellitus were independent predictors of CD. Among women with EFW ≥3,800 g and diabetes mellitus, the risk of CD was double that of those without diabetes and with EFW ≥ 3,800 g (31.4% vs. 15.2%, p = 0.02), although their actual birthweights were similar. Obstetrical and neonatal outcomes were similar between those with sonographic EFW ≥ 3,800 and < 3,800 g. CONCLUSION: Larger EFW increased CD risk among pregnancies with actual neonatal macrosomia. Antenatally suspected macrosomia might alter labor management due to concerns for potential complications, especially when associated with primiparity, diabetes mellitus, or maternal obesity. The increase in the CD rate did not show an association with improved maternal and neonatal outcomes. KEY POINTS: · Antenatally suspected macrosomia might alter labor management due to concerns about complications.. · Larger EFW increased cesarean delivery risk among pregnancies with actual neonatal macrosomia.. · The increase in the cesarean delivery rate was not associated with improved outcomes..
ABSTRACT
BACKGROUND: Preeclampsia is a unique vascular disease during pregnancy that generally appears after 20 of weeks gestation or until 6 weeks after delivery. Left undiagnosed, preeclampsia can lead rapidly to death of both mother and fetus. OBJECTIVES: To verify the efficacy of peripheral blood inflammatory markers (BIMs)in diagnosing preeclampsia and compare them with results from other studies. METHODS: Our retrospective case-control study comprised two patient groups. Pregnant women with preeclampsia and pregnant women without preeclampsia were compared for BIMs: neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and mean platelet volume (MPV). The primary endpoint of our research was to assess the predictive power of BIMs for preeclampsia diagnosis. RESULTS: The sample size was calculated based on expected differences of BIMs between the control and study groups. Comparison of quantitative variables was conducted with independent sample t-test or alternatively by Wilcoxon rank sum test. The MPV values were slightly higher in the preeclampsia group, but not statistically significant. NLR and PLR did differentiate between study and control groups. CONCLUSIONS: The diagnostic accuracy of BIMs is unsatisfactory for preeclampsia diagnosis. Discrepancies concerning these values need to be clarified. Further large prospective studies are necessary to validate the potential factor accuracy in preeclampsia diagnosis.
