Case ReportsSuggested ultrasound parameters for the assessment of fetal well-being during chronic hemodialysis.
There are no published guidelines on how to assess fetal well-being during hemodialysis. We have developed a specific protocol of renal and obstetric interventions to ensure that hemodialysis is associated with minimal changes in fetal status. ⋯ We found that, by strict adherence to these guidelines, there were no significant alterations in maternal mean arterial blood pressure, continuous fetal heart rate tracings, uterine artery systolic/diastolic ratios, or umbilical artery systolic/diastolic ratios. We conclude that stable uteroplacental and fetal perfusion can be maintained during chronic hemodialysis in pregnancy by adhering to a specific set of precautions.
