Background:
@EN It is invasive and accompanies various risks to insert pulmonary artry catheter in order to measure mixed venous oxygen saturation (SvO2) that is associated with patient's clinical course and prognosis. If there is relationship between
central
venous oxygen saturation (ScvO2)and mixed venous oxygen saturation, we an use the central venous oxygen saturation instead of mixed venous oxygen saturation to monitor and treat patients.
@ES Methods:
@EN We inserted the Swan-Ganz catheter in 20 patients(male 8, female 12) scheduled for undergoing open heart surgery and accomplished the blood gas analysis of the radial arterial blood, central venous blood and mixed venous blood during
postoperative
respiratory care in intensive care unit at F1O2 1.0, 0.6 and 0.4 in order.
@ES Results:
@EN There was no significant difference between central venous blood and mixed venous blood in respect to pH, PCO2, PO2 except the mixed venous blood pH at H1O2 0.6 that is greater than the cenral venous blood pH at F1O2 0.6 Central venous oxygen
saturation and mixed venous saturation were not significantly different and showed the following close relationship : SvO2(%)=15.41+0.80×ScvO2(R=0.88, p<0.05). In respect to the difference according to the variation F1O2,the SO2 and PO2 at F1O2
1.0
were higher than the SO2 and PO2 at F1O2 0.6 and 0.4, but the difference between F1O2 0.6 and 0.4 was not significant.
@ES Conclusion:
@EN We might conlcude that central venous oxygen saturation might be replaced for the mixed for the mixed venous oxygen saturation in respiratory care open heart surgery in adults.
