Comparative Analysis of Maternal and Fetal Outcomes of Pregnancies Complicated and Not Complicated with Hyperemesis Gravidarum Necessitating Hospitalization.

OBJECTIVE

To compare maternal and fetal outcomes of pregnancies complicated and not complicated with hyperemesis gravidarum (HG) necessitating hospitalization.

METHOD

A total of 386 women with singleton deliveries between March 2015 and January 2018 were included in this retrospective single-center study. Of 386 women, 186 women (mean±SD age: 30.7±5.9 years) who were hospitalized with HG within the first 20 weeks of gestation comprised the hyperemetic pregnancy group, while 200 women without HG during pregnancy served as a control group.

RESULTS

No significant difference was noted between the HG and control groups in terms of maternal characteristics, gestational age (median 38.6 and 39.0 weeks, respectively), type of delivery (normal spontaneous delivery in 78.0% vs 80.0%), fetal gender (female: 53.2% vs 48.5%), birthweight (median 3250 g vs 3275 g) and 5-min APGAR scores (≥7 in 97.3% vs 97.5%, respectively). Adverse pregnancy outcomes were also similar between groups including preterm birth (8.1% vs 11.0%, respectively), SGA (5.9% vs 9.5%), hypertensive disorder (5.4% vs 7.5%), placental abruption (1.1% vs 0.5%,), stillbirth (0.0% vs 0.5%) and GDM (3.8%vs 2.5%). Weight loss during pregnancy was evident in 91.3% of women in the HG group, while none of women in the control group had weight loss during pregnancy (p<0.001).

CONCLUSIONS

The findings of this study indicate that HG may not be related with adverse fetal and prenatal outcomes and this conclusion needs to be clarified with large-scale investigations.
