Abstract：Objective To compare the guiding effects of pulse indicator continuous cardiac output (PiCCO) monitoring and Swan-Ganz monitoring in rehydration treatment in patients with acute inferior wall myocardial infarction.Methods The patients (n=32, male 22, female 10, aged from 41 to 82 and average age=62.96±11.40) were chosen from Jan. 2013 to Jan. 2015. Through rehydration treatment, the cardiac output (CO) was compared between 2 monitoring methods, and the changes of CO, central venous pressure (CVP) and pulmonary capillary wedge pressure (PCWP) as the variation of fluid supplement volume were observed. The relationship among CVP, global end-diastolic volume index (GEDI) and extravascular lung water index (EVLWI) were observed.Results Within the set range of fluid supplement volume, the difference in CO comparison between 2 monitoring methods had no statistical significance before and after rehydration treatment (allP>0.05). The hemodynamic key index (CO) monitored by 2 methods had the same results. There was no correlation between CVP monitored by Swan-Ganz and EVLWI monitored by PiCCO (r=0.143,P>0.05), and GEDI detected by PiCCO was positively correlated to EVLWI detected by PiCCO (r=0.769,P<0.001).Conclusion The hemodynamic key index (CO) monitored by 2 methods had the same results. Swan-Ganz monitoring is more accurate but has more difficulty in operation with more complications because of trans-right cardiac system. PiCCO is easier in operation with fewer injuries because of non trans-right cardiac system, which can provide more real time and dynamic hemodynamic parameters.
