Abstract
To determine whether indocyanine green (ICG) and glucose dilutions can detect generalized capillary protein leakage in septic patients without requiring repeated measurements. Prospective, clinical study. General intensive care unit. Twelve consecutive patients who met the criteria of sepsis and 16 consecutive acute myocardial infarction (AMI) patients without any underlying pathology inducing generalized protein capillary leakage. Both ICG 25 mg and glucose 5 g were administered simultaneously, to calculate the plasma volume determined by the ICG dilution method (PV-ICG) and the initial distribution volume of glucose (IDVG), on day 1 of sepsis or on day 1 of hospitalization for the AMI patients. The relationship between these two volumes and the PV-ICG/IDVG ratio was evaluated in two patient groups. Although the IDVG of the two patient groups was not statistically different, the PV-ICG in the septic patients was higher than that in the AMI patients (pp0.45, which was not observed in any of the AMI patients. The PV-ICG/IDVG ratio in the septic patients correlated inversely with the total plasma protein concentration (r2 = .46,p2 = .42,p Our results indicate that overestimation of the PV-ICG can occur in septic patients and, further, suggest that simultaneous measurement of the two distribution volumes would help predict generalized capillary protein leakage in septic patients without repeated measurement.Keywords
