The Comparison Of The Measurements Of Cardiac Output Between PICCO And Color Doppler Echocardiography In Patients With Septic Shock

Objective: To compare the measurements of cardiac output between PiCCO and colorDoppler echocardiography and evaluate the consistency in patients with septic shock.Methods:25septic shock in-patients treated in the department of Intensive Critical Carewere chosen from Dec,2011to Sep,2012. Heart rate, invasive mean arterial pressure andsystematic circulatory vascular resistant index at different times were measured bycontinuous PiCCO monitoring.The cardiac output at the same time was measured by thePiCCO thermodilution technology， pulse contour technology and color Dopplerechocardiography. Results: There were no significant differences of the measurements ofcardiac output between the PiCCO thermodilution technology and echocardiography atdifferent times(p＞0.05)；The cardiac output measured by pulse contour technology wassignificantly lower than that by echocardiography at2ndh(p＜0.05)，there were nosignificant differences at other times. Conclusion: When the peripheral vascular resistancechanges rapidly， the consistency of PiCCO thermodilution technology andechocardiography is better than that of pulse contour technology and echocardiography inthe measurements of cardiac output.When patients have the similar hemodynamic changeslike septic shock, we’d better use the PiCCO thermodilution technology to measure thecardiac output.
