“…The aim of a TEBT continuous monitor would be to timely detect hemodynamic abnormalities, initiate, and monitor the appropriate therapy. In neonatology, BR is increasingly used to monitor CO [39], ductal persistency [24], thoracic fluid content [40], haemodynamic changes during blood transfusion [41], septic shock [42], hypoplastic heart [43] and adverse neonatal outcomes [44]. It is therefore of utmost importance that an TEBT monitor is accurate in its trending ability.…”

Introduction: It is unknown whether bioreactance (BR) can accurately track cardiac output (CO) changes in preterm neonates. Methods: A prospective observational longitudinal study was performed in stable preterm infants (<37 weeks) during the first 72 h of life. Stroke volume (SV) and CO, as measured by BR and transthoracic echocardiography, were compared. Results: The mean gestational age (GA) was 31.3 weeks and mean birth weight (BW) was 1,563 g. Overall, 690 measurements were analysed for trending ability by 4-quadrant and polar plots. For non-weight-indexed measurements, 377 (54.6%) lay outside the 5% exclusion zone, the concordance rate was poor (77.2%) with a high mean angular bias (28.6°), wide limits of agreement and a poor angular concordance rate (17.4%). Neither GA, BW nor respiratory support mode affected trending data. Patent ductus arteriosus, postnatal age, and CO level had variable effects on trending data. Trending data for 5 and 10% exclusion zones were also compared. Conclusion: The ability of BR to track changes in CO is not interchangeable with CO changes as measured by echocardiography. BR, as a trend monitor for changes in CO or SV to determine clinical decisions around interventions in neonatology, should be used with caution.

“…The electrical cardiometry-based TFC showed useful results in evaluation of the volume status of patients undergoing autologous blood transfusion [9]. In late preterm and term newborn, TFC correlated with the occurrence of respiratory distress in the first 24 h after birth [19]. Our group had recently evaluated TFC in pre-eclamptic mothers and reported that TFC could detect mothers with high risk for pulmonary edema [10].…”

Thoracic fluid content: a novel parameter for predicting failed weaning from mechanical ventilation

et al. 2020

Background: Weaning of patients from the mechanical ventilation remains one of the critical decisions in intensive care unit. This study aimed to evaluate the accuracy of thoracic fluid content (TFC) as a predictor of weaning outcome.Methods: An observational cohort study included 64 critically ill surgical patients who were eligible for extubation. Before initiating the spontaneous breathing trial, the TFC was measured using the electrical cardiometry technology. Patients were followed up after extubation and divided into successful weaning group and failed weaning group. Both groups were compared according to respiratory and cardiovascular parameters. Receiver operating characteristic (ROC) curves were constructed to evaluate the ability of TFC to predict weaning outcome. Results: The number of successfully weaned patients was 41/64 (64%). Twenty (31%) patients had impaired cardiac contractility, and of them, 13/20 (64%) patients were successfully extubated. Both groups, successful weaning group and failed weaning group, were comparable in most of baseline characteristics; however, the TFC was significantly higher in the failed weaning group compared to the successful weaning group. The area under the ROC curves (AUCs) showed moderate predictive ability for the TFC in predicting weaning failure (AUC [95% confidence interval] 0.69 [0.57-0.8], cutoff value > 50 kΩ −1 ), while the predictive ability of TFC was excellent in the subgroup of patients with ejection fraction < 40% (AUC [95% confidence interval 0.93 [0.72-1], cutoff value > 50 kΩ −1 ). Conclusions: Thoracic fluid content showed moderate ability for predicting weaning outcome in surgical critically ill patients. However, in the subgroup of patients with ejection fraction less than 40%, TFC above 50 kΩ −1 has an excellent ability to predict weaning failure.

Bioimpedance analysis is an easy, rapid, cheap, noninvasive, effective, and portable technique that can be utilized in several pediatric health conditions. The fluid status evaluation, edema, obesity, malnutrition, inflammation, infection, pain, attention deficit/hyperactivity disorder, nephrourological evaluation, gastroesophageal reflux, and neonatal problems are some of the issues studied with bioimpedance. As the pediatric-age group is usually difficult to manage, such practical and accurate methods are promising for better results.

Thoracic fluid content by electric bioimpedance correlates with respiratory distress in newborns
