Prospective observational study finds changes in lung aeration post-anesthesia in laparoscopic surgery, suggesting ultrasonography's importance.
Our study found a progressive loss of lung aeration after the induction of general anesthesia in laparoscopic cholecystectomy, extending up to the 24-h perioperative period. However, diaphragmatic excursion remained unchanged. The study also suggests that LUS is a valuable tool for detecting perioperative atelectasis and quantifying the aeration loss.
