ReviewShedding light on mitochondrial function by real time monitoring of NADH fluorescence: II: human studies.
Monitoring the mitochondrial function, alone or together with microcirculatory blood flow, volume and hemoglobin oxygenation in patients, is very rare. The integrity of microcirculation and mitochondrial activity is a key factor in keeping normal cellular activities. Many pathological conditions in patients are directly or indirectly related to dysfunction of the mitochondria. ⋯ In part I, the detailed technological aspects of NADH monitoring were described. Typical results accumulated in our studies since the mid-1990s are presented as well. We were able to apply the fiber optic based NADH fluorometry to several organs monitored in vivo in patients under various pathophysiological conditions.

Comparative StudyComparing hemodynamic effects with three different measurement devices, of two methods of external leg compression versus passive leg raising in patients after cardiac surgery.
External leg compression (ELC) may increase cardiac output (CO) in fluid-responsive patients like passive leg raising (PLR). We compared the hemodynamic effects of two methods of ELC and PLR measured by thermodilution (COtd), pressure curve analysis Modelflow™ (COmf) and ultra-sound HemoSonic™ (COhs), to evaluate the method with the greatest hemodynamic effect and the most accurate less invasive method to measure that effect. We compared hemodynamic effects of two different ELC methods (circular, A (n = 16), vs. wide, B (n = 13), bandages inflated to 30 cm H2O for 15 min) with PLR prior to each ELC method, in 29 post-operative cardiac surgical patients. ⋯ Bland-Altman and polar plots showed lower limits of agreement with changes in COtd for COmf than for COhs. The circular leg compression increases CO more than bandage compression, and is able to increase CO as in PLR. The less invasive Modelflow™ can detect these changes reasonably well.
