ABSTRACT
OBJECTIVE:
To observe the hemodynamic changes in patients undergoing pericardiectomy at different operational stages.METHODS:
Totally 16 consecutive patients receiving radical pericardiectomy were enrolled in this observational study. Hemodynamic variables were monitored continuously by pulse-indicated continuous cardiac output(PiCCO)system. Totally,three sets of intraoperative hemodynamic parameters were obtained at three different stages of pericardiectomy.RESULTS:
During the pericardiectomy,the cardiac index[CI,(1.9±0.6),(2.7±0.6),(3.0±0.5)L·min(-1)·m(-2);P<0.05]and stroke volume index[SI,(22.5±8.7),(29.9±8.5),(30.1±8.5)dyn·s·cm(-5)·m(2);P<0.05]showed significant improvement,whereas central venous pressure[CVP,(17.1±5.0),(13.3±3.9),(12.3±3.0)mmHg;P<0.05]decreased significantly. Global end-diastolic volume index[GEDVi,(533±156),(580±153),(559±144)ml·m(-2);P<0.05]increased and stroke volume variation[SVV,(15.6±6.1)%,(10.8±4.2)%,(9.4±5.4)%;P<0.05]decreased intra-operatively. The majority of the above-mentioned hemodynamic improvements occurred after the resection of pericardium over the left ventricular outflow tract(LVOT).CONCLUSIONS:
PiCCO system can serve as a reliable,less invasive hemodynamic monitoring method during pericardiectomy. Resection of the pericardium over the LVOT is the most important step of the pericardiectomy.
