The effects of anesthesia induction and positive pressure ventilation on right-ventricular function: an echocardiography-based prospective observational study.

ABSTRACT: BACKGROUND:General anesthesia induction with the initiation of positive pressure ventilation creates a vulnerable phase for patients. The impact of positive intrathoracic pressure on cardiac performance has been studied but remains controversial. 3D echocardiography is a valid and MRI-validated bed-side tool to evaluate the right ventricle (RV). The aim of this study was to assess the impact of anesthesia induction (using midazolam, sufentanil and rocuronium, followed by sevoflurane) with positive pressure ventilation (PEEP 5, tidal volume 6-8 ml/kg) on 2D and 3D echocardiography derived parameters of RV function. METHODS:A prospective observational study on fifty-three patients undergoing elective cardiac surgery in a tertiary care university hospital was designed. Transthoracic echocardi
