Bioelectrical impedance analysis in the assessment of pre-eclampsia.

Purpose: Aim of this prospective investigation was to assess pre-eclampsia by bioelectrical impedance analysis (BIA).

Methods: A total of 22 pre-eclamptic as well as matched (patients' age, gestational age, parity, gravidity) healthy pregnant women underwent whole body BIA on admission and then, pre-eclamptic patients, every 2 days until childbirth. For all measured BIA single values and their corresponding reference value mean, standard deviation, minimum and maximum were calculated to compare pre-eclamptic women with corresponding reference values.

Bioelectrical impedance analysis in pregnancy: reference ranges.

Aim: To generate reference values for bioelectrical impedance analysis (BIA) in a German collective of healthy pregnant women.

Materials And Methods: A total of 90 women with a singleton gestation from 23+0 to 40+6 weeks of pregnancy were enrolled from April 2012 until May 2013. Each week of gestation was represented by the same number of women (n=5).

Whole-body bioelectrical impedance analysis in assessing upper-limb lymphedema after breast cancer therapy.

Aim: The purpose of this prospective study was to evaluate single-frequency whole-body bioelectrical impedance analysis (BIA) as a predictor for the onset of edema of the upper limb in patients undergoing treatment for breast cancer.

Materials And Methods: Whole-body BIA was performed before surgery, as well as at two days, and one, three, six and twelve months after surgery.

Results: Sixty women undergoing breast cancer surgery were examined, with loss of follow-up of 18 patients.

Whole-body versus segmental bioelectrical impedance analysis in patients with edema of the upper limb after breast cancer treatment.

Aim: The purpose of this study was to compare whole-body (50 kHz alternating current) and segmental (5 kHz alternating current) bioelectrical impedance analysis (BIA) in the assessment of manifested edema of the upper limbs.

Patients And Methods: Whole-body and segmental BIA were performed in 30 patients with edema of the upper limb following breast cancer treatment.

Results: Pearson correlation coefficient comparing both measurements was 0.

Comparing bioelectrical impedance values in assessing early upper limb lymphedema after breast cancer surgery.

Aim: The purpose of this prospective study was to evaluate resistance (R) and phase angle (Pa) determined by single-frequency whole-body bioelectrical impedance analysis (BIA), as predictors for the early onset of edema of the upper limb in patients undergoing surgical treatment for breast cancer.

Materials And Methods: Whole-body BIA was performed before surgery, as well as at two days, at one and three months after surgery.

Results: A total of 33 women undergoing breast cancer surgery were examined.
