The influence of venovenous renal replacement therapy on measurements by the transpulmonary thermodilution technique.

Background: Use of the transpulmonary thermodilution technique has been suggested for extended hemodynamic monitoring in critically ill patients. However, many of these patients also require renal replacement therapy (RRT). Therefore, we analyzed the influence of venovenous RRT on measurement of cardiac index (CI), intrathoracic blood volume index (ITBVI), and extravascular lung water index (EVLWI).

Increasing cardiac output by epinephrine after cardiac surgery: effects on indocyanine green plasma disappearance rate and splanchnic microcirculation.

Objective: The effects of increasing cardiac output by epinephrine on indocyanine green plasma disappearance rate (ICG-PDR) and gastric mucosal PCO(2) (P(R)CO(2)) were studied as indicators of splanchnic microcirculation.

Design: A prospective clinical study.

Setting: Intensive care unit of a university hospital.

Influence of an acute increase in systemic vascular resistance on transpulmonary thermodilution-derived parameters in critically ill patients.

Objective: The transpulmonary thermodilution technique enables measurement of cardiac index (CI), intrathoracic blood volume (ITBV), global end-diastolic volume (GEDV), and extravascular lung water (EVLW). In this study, we analyzed the robustness of this technique during an acute increase in systemic vascular resistance (SVR).

Design: Prospective, clinical study.
