Excerpt

Dear Sir: Extended hemodynamic monitoring by the transpulmonary thermodilution technique, which has been shown to be sufficiently accurate when compared to the double-indicator technique [1], has the potential for reduced length of mechanical ventilation and stay in the ICU [2]. However, reliability of this technique has been questioned, i.e., during extracorporeal circulation. Previously, it was shown in patients with preserved cardiac output (CO) that running renal replacement therapy has no clinically relevant impact [3]. Here, data are provided on the influence of a pumpless extracorporeal lung assist system on transpulmonary thermodilution-derived variables. …
