Haemodynamic evaluation at term: is it predictive of adverse perinatal outcomes? A monocentric retrospective study

Objective. Aim of this study is to describe the correlation be­tween maternal haemodynamic parameters obtained through USCOM performed beyond term and adverse perinatal out­comes (APO).
Materials and Methods. This is a retrospective monocentric de­scriptive study promoted by AOU Policlinico di Modena. The study period is January to December 2023. 157 patients have been enrolled: 124 of them were low risk pregnancies while 33 were affected by hypertensive disorder of pregnancy (HPD) and/or foetal growth restriction (FGR), in charge at our high risk pregnancy clinic. All of them received USCOM evaluation beyond term. APO at birth were defined as the presence of one of those complications: emergency caesarean section (eCS)/ operative delivery (OD), postpartum haemorrhage (PPH), NICU admission, 5-minute APGAR < 7. Data have been col­lected from medical records and elaborated thanks to the soft­ware SPSS (version 29).
Results. At univariate analysis, pregnancies complicated by HDP and/or FGR presented higher values of PAS, PAD, PAM and CI (P-values of 0.002, 0.005, 0.006, 0.003, respectively). Moreover, at logistic multivariate regression we found that higher values of RVS (P-value = 0.041) and reduction of CO (P-value = 0.004) are statistically related to higher risk of APO independently by the presence of Hypertension and/or FGR.
Conclusions. Although a bigger sample is mandatory, our analysis shows the possibility to predict undesirable obstet­rical outcomes performing USCOM evaluation at term, espe­cially in high-risk pregnancies.
