Esophageal ultrasound and floating catheter in different coronary artery bypass grafting for cardiac function and pulmonary artery pressure / 局解手术学杂志

ABSTRACT

Objective To compare the cardiac function and pulmonary arterial pressure of the patients undergoing surgery of off-pumpcoronary artery bypass grafting(CABG) and on-pump-CABG by the esophageal ultrasound and the floating catheter,to find out what kind of coronary artery bypass grafting is better for cardiac function.Methods The design of this experiment used a completely randomized block design,36 patients were randomly divided into two groupsgroup A(off-pump-CABG),group B (on-pump-CABG),18 cases in each group.The detection time point set after all the operation had been completed.The pulmonary arterial systolic pressure,the right ventricular end diastolic volume,the right ventricular ejection fraction and the left ventricular end diastohc pressure were measured by the esophagus ultrasound and floating catheter.Results There was no significant difference in esophagus ultrasound and floating catheter between the two groups (P ＞ 0.05).The results of echocardiography and floating catheter showed that the pulmonary artery diastolic blood pressure was lower in group A than that in group B (P ＜ 0.05).The heart function in group A was better than that of group B (P ＜ 0.05).Conclusion The effect of the ultrasonic heartbeat graph and the monitoring of the floating catheter in the off-pump-CABG and on-pump-CABG are basically the same.The heart function in off-pump-CABG group was better than that of on-pump-CABG.The reason may be that the off-pump-CABG is less likely to be associated with the flow dynamics of the blood flow dynamics and the cell factor associated with the non physiological ducts.
