Abstract:
Objective: To evaluate the consistency of transesophageal echocardiography (TEE) and pulmonary artery catheter (PAC) method in monitoring cardiac volume load and cardiac hemodynamic indexes.Methods: A total of 45 patients undergoing coronary artery bypass grafting in our hospital were selected.The right ventricular end-diastolic volume (RVEDV), right ventricular end-systolic volume (RVESV) and right ventricular ejection fraction (RVEF) were monitored during surgery by TEE and PAC respectively.Consistency of monitored data was compared between two methods.Results: Both TEE and PAC indicated that compared with baseline level, after loading, there were significant rise in RVEDV [TEE: (38±6)ml vs.(51±9ml), PAC: (153±17)ml vs.(188±19)ml], RVESV [TEE: (19±4)ml vs.(33±5)ml, PAC: (92±16)ml vs.(110±23)ml], P<0.01 all, but there was no significant change in RVEF, P>0.05.Before therapy, RVEDV, RVESV and RVEF monitored by PAC and TEE showed significant positive correlation, and all relevant coefficients were >0.8 (r=0.844, 0.862, 0.916, P<0.01 all);after therapy, correlation of RVEDV and RVESV significantly reduced to <0.6 (r=0.552, 0.579, P<0.05 both), but RVEF correlation remained >0.8 (r=0.892, P<0.01).Conclusion: In clinical monitor, the consistency of TEE and PAC is high,the former is non-traumatic,and is more convenient for clinical use.
