“…The achievement of normal fluid status is essential in dialysis patients to prevent complications of fluid overload on the cardiovascular system such as hypertension, LVH and cardiac failure. There are several objective methods to estimate dry weight (DW) in peritoneal dialysis patients, such as measurements of inferior vena cava diameter, natriuretic peptides, determination of ECW/ICW or ECW/ TBW ratio in addition to clinical evaluation (3,4). The use of these techniques in daily clinical practice is not very efficient, because their accuracy is limited and there are no certain cutoff levels which indicate normal fluid status (3)(4)(5).…”

“…Available methods to assess fluid status include measurement of natriuretic peptides (atrial natriuretic peptide, brain natriuretic peptide, N-terminal fragment of B-type natriuretic peptide (NT-proBNP)), inferior vena cava diameter, continuous relative blood volume monitoring, and bioimpedance analysis. Bioimpedance analysis is a non-invasive and low cost means to objectively measure body fluid content in dialysis patients (3,4). A number of methods based on conventional bioimpedance spectroscopy (BIS) techniques can predict normal body fluid status, such as the extracellular water to total body water (ECW/ TBW), and extracellular to intracellular water ratios (ECW/ICW) (5)(6)(7).…”

“…But this method is not very suitable for premature infants with extremely low body weight either, and other medical problems because of a high frequency of lumbar puncture could cause infections and other shortcomings including bradycardia or apnea during surgery, difficulty of manipulation and a painful experience for the infants [8,9,10]. Moreover, due to the absence of a communication between ventricle and marrow cavity, CSF drainage by serial lumbar puncture has little efficacy in the treatment of obstructive hydrocephalus [21]. …”

Aims: To investigate the effectiveness of subcutaneous reservoir drainage as a treatment for the different types of posthemorrhagic hydrocephalus in premature infants. Methods: 11 premature infants with posthemorrhagic hydrocephalus underwent subcutaneous reservoir embedment surgery, and cerebrospinal fluid (CSF) was drained via the reservoir intermittently for 8 weeks. During the period of drainage, ultrasound and computerized tomography were used to measure ventricle size. CSF examinations were performed routinely to assess the presence of intraventricular hemorrhage (IVH) and/or infection. Results: (1) Five infants were diagnosed as having obstructive hydrocephalus; 2 had nearly normal ventricle sizes with treatment and drainage was stopped after 8 weeks, 2 had nearly normal ventricle sizes after 4 more weeks of drainage, and 1 underwent ventriculoperitoneal shunt (V-P shunt) surgery due to failure of ventricle size reduction. (2) Six infants were diagnosed as having communicating hydrocephalus; 4 had further enlarged ventricle size after 8 weeks and underwent V-P shunt surgery, 1 had treatment aborted at week 8 of drainage, and only 1 had moderate reduction of ventricle size after 8 weeks. (3) None of the 11 infants had progressive IVH and/or intracranial infection during drainage. Conclusions: Subcutaneous reservoir drainage is a suitable and safe treatment for posthemorrhagic hydrocephalus in premature infants. It is more effective for obstructive hydrocephalus than for communicating hydrocephalus.

“…However, they also have a significant heterogeneity, and better markers are needed. The feasibility of segmental bioimpedance measurement [5] in the determination of segmental volumes and regional fluid shifts to overcome the limitations of whole-body impedance methods is an alternative. The bioelectrical impedance vector analysis BIVA [2] is a non invasive procedure easily applicable in the clinic due to its sensitivity to detect changes in the hydration of soft tissues.…”

Abstract. Heart Failure (HF) is a clinical syndrome characterised by signs of systemic and pulmonary fluid retention, shortness of breath and/or fatigue. There is a lack of reliable indicators of disease state. Benefits and applicability of non-invasive bioimpedance measurement in the hydration state of soft tissues have been validated, fundamentally, in dialysis patients. Four impedance configurations (2 longitudinal and 2 transversal) were analyzed in 48 HF patients (M=28, F=20) classified according to a clinical disease severity score (CDSS) derived from the Framingham criteria: CDSS 2 (G1: M= 23, F= 14) and CDSS>2 (G2: M= 5, F= 6). The aim of this study is to analyze longitudinal and transversal bioimpedance measurement at 50 kHz, in addition to clinical diagnosis parameters of heart failure, including: clinical disease severity score (CDSS) and a biomarker concentrations (NTproBNP). The Kolmogorov-Smirnov test was used for the normality test of all variables. The CDSS, NTproBNP and impedance parameters between groups (G1 and G2) were compared by mean of Mann Withney U-test. The statistical significance was considered with P < 0.05. Whole-body impedance measured was analyzed using RXc graph.
