Abstract:
Objective To summarize anesthetic management for 56 patients undergoing off-pump coronary artery bypass grafting (OPCABG). Methods Recorded and analyzed the hemodynamie changes of 56 patients undergoing OPCABG including heart rate (HR),rate-pressure product (RPP), mean arterial pressure(MAP), mean pulmonary artery pressure(MPAP), central venous pressure (CVP), cardiac output (CO) and mixed venous oxygen saturation when left anterior descending (LAD), right coronary artery (RCA), diagonal (DiAG) and left circumflex coronary artery (LCX) was anastmosed. Results The patients undergoing OPCABG had hemodynamic fluctuation during vascular anastomosis, mainly showing MAP and CO decreased, CVP increased. The change was especially significant when the LCX or RCX was anastmosed. The based value, when LAD and RCA anastmosed of MAP were (82.0±11.7) mm Hg(1 mm Hg = 0.133 kPa), (60.1±11.5) mm Hg and (58.4±12.1) mm Hg, CO were (4.2±1.2) L/min, (3.1±0.7) L/min and (3.2±0.6) L/min, CVP were (5.6±2.6) cm H2O (1 cm H2O=0.098 kPa), (9.6±4.4) cm H2O and (9.2±3.6) cm H2O. Conclusion The hemodynamie changes during OPCABG,especially in LCX and RCA anastmesed are transient and well tolerated under suitable anesthetic management.
