Application of pulse-indicated continuous cardiac output measurement system in monitoring hemodynamics of elderly heart disease patients during off-pump coronary artery bypass grafting

Objective To monitor the hemodynamics in elderly heart disease patients during off-pump coronary artery bypass grafting (CABG) with pulse-indicated continuous cardiac output (PiCCO) system. Methods Thirty elderly patients with coronary ateroclerotic heart disease who underwent off-pump CABG were included in this study. Their ABP, HR, CVP, CO, CI, GEF, SVI, ITBI and GEDVI were measured with PiCCO system at T₀, T₁, T₂, T₃ and T₄ , respectively. Results The operation was successful for all the patients. The ABP, CVP, CO, GEF and SVI were significantly lower at T₀ than at T₃ and T₄ , and at T₀ than at T₁ (P＜ 0.05).The ITBI and GEDVI were significantly lower while the CI was significantly higher at T₃ and T₄ than at T₀ (P＜ 0.05). The patients recovered with no surgical and PiCCO manipulation-related complications. Conclusion PiCCO system is a simple and reliable device for monitoring hemodynamics in elderly coronary disease patients during off-pump CABG．
