Primary outcomePrimary: Atelectasis Area on Chest CT — 1.32; 1.41 percentage of atelectasis volume
Summary
During one-lung ventilation in thoracic surgery, the intensity of neuromuscular blockade may change the compliance and resistance of ventilated lung, thereby affecting postoperative atelectasis. The present study investigated the effect of the intensity of intraoperative neuromuscular blockade on the postoperative atelectasis using chest computerized tomography in patients receiving thoracic surgery requiring one-lung ventilation.
