title: Noninvasive cardiac output monitoring in paediatric cardiac surgery: correlation between change in thoracic fluid content and change in patient body weight.
abstract: OBJECTIVE
  Change in thoracic fluid content (TFC) derived via a bioreactance technique with a noninvasive cardiac output monitoring device (NICOM) reportedly shows a good correlation with the amount of fluid removed. The present study prospectively evaluated the utility and clinical  application of TFC in the intraoperative fluid management of paediatric patients with congenital heart disease, undergoing cardiac surgery with bioreactance-based noninvasive monitoring.
  
  
  METHODS
  Haemodynamic parameters, patient body weight and parameters derived from the NICOM device (including  cardiac output, cardiac index, TFC, percentage change in TFC compared with baseline [TFCd0%] and stroke volume variation) were recorded after anaesthesia induction but before surgical incision, and just before departure from the operating room to the intensive care unit.
  
  
  RESULTS
  In the 80  paediatric patients included in this study, linear regression analyses demonstrated good correlations between body weight gain and TFCd0%, between body weight gain % and TFCd0%, and between intra operative fluid balance and TFCd0%.
  
  
  CONCLUSIONS
  TFCd0% may be a useful indicator for intraoperative  fluid management in paediatric patients with congenital heart disease, undergoing cardiac surgery.
