Abstract
We report the successful management of dry weight in a pregnant woman requiring hemodialysis by noninvasive examination (diameter of inferior vena cava by ultrasound sonography, human natriuretic peptide (hANP), and continuous hematocrit monitoring (CRIT-LINE®)).
The patient was a 28-year old woman with a clinical history of hemodialysis for 6 years. She was admitted to our hospital at 8 weeks of gestation for management of hypertension and hemodialysis.
In setting her dry weight, we estimated the value by noninvasive examination. Her hospital course, including hemodialysis, was stable until 20 weeks of gestation. Although adequate hemodialysis and an appropriate dry weight were set, polyhydroamnious developed at 21 weeks of gestation. Thereafter, her blood pressure was extremely high. She finally delivered a baby weighing 836g by caesarian section at 28 weeks of gestation.
We conclude that setting the dry weight by noninvasive method, without complication for either the mother or fetus, is useful for maintaining a pregnant patient.
