Electrical impedance tomography-based evaluation of regional lung ventilation according to ventilation strategy during cardiopulmonary bypass in minimally invasive cardiac surgery: a prospective randomized controlled trial.

ABSTRACT:

Background

Despite the potential benefits of minimally invasive cardiac surgery (MICS), cardiopulmonary bypass (CPB) during MICS can cause pulmonary complications. However, the optimal ventilation strategy for the left lung under CPB during MICS remains unclear. Thus, this study aimed to evaluate differences in postoperative pulmonary ventilation and complications according to ventilation strategy during MICS.

Methods

This prospective, randomized controlled trial included 60 patients who underwent MICS with one-lung ventilation. They were randomly assigned to either the non-ventilation (NV) group, in which ventilation was halted during CPB, or the ventilation (V) group, in which ventilation at a tidal volume of 5 mL/kg was maintained during CPB.
