Evaluation of Early Phase Change of Right Ventricular Hemodynamic after Lung Resection by Doppler Echocardiography / 中国医师杂志

ABSTRACT

Objectives To determine the changes of right ventricular hemodynamic in the early phase after lung resection and non-lung resection thoracotomy by Doppler echocardiography and to investigate the correlation with preoperative lung function.Methods 55 patients who underwent thoracotomy were divided into two groups. In group A 15 patients underwent non-lung resection thoracotomy; in group B 40 patients underwent lung resection. The group B were subdivided into group B1 (n=23) and group B2 (n=17), acording to the preoperative lung function results: Artery blood gas analysis were measured and right ventricular hemodynamic indices were calculated by Doppler echocardiography before and after operation,respectively.Results Right ventricular ejection fraction (RVEF) and artery oxygen pressure(PaO 2) significantly decreased (P
