Strengths
One strength of this study is that the hemodynamic assessment was performed in standardized situation, without confounding factors (labor pain, different room conditions, etc.) that could compromise hemodynamic parameters. Unlike to our previous study, evaluating maternal hemodynamics before the labor onset, has been possible to standardize the evaluation in order to assess if the hemodynamic profile, at rest, in a non-stress condition, is different in women at risk of delivery complications.
Another key strength is that the labor management team was not informed of hemodynamic evaluation results collected before the labor onset.
