Cardiac output (CO) can be measured using the transpulmonary thermodilution (TPTD) technique. TPTD is considered to be the gold standard in pediatric patients. We studied the influence of high levels of EVLW on the reliability of CO measurement using the TPTD technique in a pediatric animal model.
Anesthetized, mechanically ventilated lambs were instrumented with a COLD® (Pulsion Medical Systems, Munich, Germany) catheter and underwent repetitive saline lavage (10 to 30 ml/kg) of the lung. CO was measured using the single indicator TPTD method (COTPTD) and compared with simultaneous measurement of CO using an ultrasound perivascular flowprobe (Transonic Systems, USA) around the main pulmonary artery (COMPA). EVLW was assessed by the transpulmonary double indicator technique with intravenous injections of ice-cold indocyanine green (ICG).
In circumstances of largely increased extravascular lung water, CO can reliably be measured using the TPTD technique.
