Ocena neprekinjene termodilucijske metode za merjenje minutnega srčnega iztisa = Evaluation of continuous thermodilution method for cardiac output measurementParežnik, Roman ...Background. Continuous monitoring of haemodynamic variables is often necessaryfor detection of rapid changes in critically ill patients. In our patients recently introduced continuous thermodilution ... technique (CTD) for cardiac output measurement was compared to bolus thermodilution technique (BTD) which is a golden standard method for cardiac output (CO) measurement inintensive care medicine. Methods. Ten critically ill patients were included in a retrospective observational study. Using CTD method cardiac output was measured continuously. BTD measurements using the same equipment were performed intermittently. The data obtained by BTD were compared to those obtained by CTD just before the BTD (CTD-before) and 2-3 minutes after the BTD(CTD-after). The CO values were divided into three groups: all CO values, CO.4.5 L/min, CO<4.5 L/min. The bias (mean difference between values obtained by two methods), standard deviation, 95% confidence limits and relative error were calculated and the linear regression analysis was performed. t-test for pared data was used to compare the biases for CTD-before and CTD-after for an individual group. The p value of less than 0.05 was considered statistically significant. Results. A total of 60 data triplets were obtained. CTD-before ranged from 1.9 L/min to 12.6/min, CTD-after from 2.0 to 13.2 L/min and BTD from 1.9 to 12.0 L/min. For all CO values the bias for CTD-before was 0.13 +- 0.52 L/min (95% confidence limits 1.17-0.91 L/min), relative error was 3.52+-15.20%, linear regression equation was CTD-before + 0.96 x BTD + 0.01 and Pearsons correlation coefficient was 0.95. The values for CTD-after were 0.08 +- 0.46 L/min (1.0-0.84 L/min), 2.22 +- 9.05%, CTD-after =0.98 x BTD + 0.01 and 0.98 respectively.
