“…A reduced fluid intake can cause dehydration, electrolyte imbalance, and arterial hypotension. On the other hand, an excessive fluid intake can cause peripheral edema, patent ductus arteriosus, congestive heart failure, bronchopulmonary dysplasia, cerebral intraventricular hemorrhage, and necrotizing enterocolitis (1).…”

The assessment of fluid volume in neonates by a noninvasive, inexpensive, and fast method can contribute significantly to increase the quality of neonatal care. The objective of the present study was to calibrate an acquisition system and software to estimate the bioelectrical impedance parameters obtained by a method of bioelectrical impedance spectroscopy based on step response and to develop specific equations for the neonatal population to determine body fluid compartments. Bioelectric impedance measurements were performed by a laboratory homemade instrument. The volumes were estimated in a clinical study on 30 full-term neonates at four different times during the first month of life. During the first 24 hours of life the total body water, extracellular water and intracellular water were 2.09 ± 0.25, 1.20 ± 0.19, and 0.90 ± 0.25 liters, respectively. By the 48th hour they were 1.87 ± 0.27, 1.08 ± 0.17, and 0.79 ± 0.21 liters, respectively. On the 10th day they were 2.02 ± 0.25, 1.29 ± 0.21, and 0.72 ± 0.14 liters, respectively, and after 1 month they were 2.34 ± 0.27, 1.62 ± 0.20, and 0.72 ± 0.13 liters, respectively. The behavior of the estimated volume was correlated with neonatal body weight changes, leading to a better interpretation of such changes. In conclusion, this study indicates the feasibility of bioelectrical impedance spectroscopy as a method to help fluid administration in intensive care neonatal units, and also contribute to the development of new equations to estimate neonatal body fluid contents.

“…A reduced liquid intake can cause dehydration, electrolytic unbalance and hypotension. On the other side, an excessive intake (more than 170ml/Kg/day) can cause peripheral edema, congestive heart failure, bronchopulmonary dysplasia, necrotizing enterocolitis, cerebral intraventricular hemorragy and possible symptomatic patent ductus arteriosus [1].…”

“…This disproportion is due to the transference of extracellular water to the intracellular compartment that occurs during the pregnancy. In the first sixteen weeks of pregnancy, the total body water is 90% of fetal weight and the proportion of extracellular and intracellular water is 65% and 25%, respectively [1]. In the term, this compartments change to 45% and 35% of total body weight, respectively [1] and the total body water constitute 80% of weight [2].…”

In the term, this compartments change to 45% and 35% of total body weight, respectively [1] and the total body water constitute 80% of weight [2]. This alteration in the body fluids shows that the total body water and extracellular water diminish with the increase of gestational age.…”

“…Nevertheless, this relation can not detect the changes in intra and extra cellular volume [1,4]. So, due to the changes that can occur in the extracellular volume without total corporal volume alteration, the weight is not a confident parameter to monitor the fluid balance.…”

Abstract-The amount of liquid intake in neonatal care should be preceded by the knowledge of the neonate hydro-balance. A reduced liquid intake can cause dehydration, electrolytic unbalance and hypotension. By the other hand, an excessive intake can cause peripheral edema, congestive heart failure, among others problems. Thus, the assessment of the liquid compartment in neonates, by a non-invasive, non-expensive and fast method can contribute to increase the quality of the neonatal care. Bioimpedance has been used to assess fluid volumes in adults, but a very few works has been published in neonatal studies, specially using techniques able to observe the intra and extra-cellular compartments separately. The present work aims to study the fluid balance in neonates using a recent bioimpedance spectroscopy method and correlate the results with clinical findings.
