U.S., Nov. 6 -- ClinicalTrials.gov registry received information related to the study (NCT07918495) titled 'Effect of Prophylactic Dexamethasone vs Placebo on Airway Dimensions Assessed by Ultrasonography in Patients Undergoing Laparoscopic Cholecystectomy' on Oct. 31.

Brief Summary: During laparoscopic surgery, the abdomen is inflated with carbon dioxide gas (pneumoperitoneum), which alters venous return and fluid distribution, potentially leading to swelling in the tissues of the upper airway. The placement of a breathing tube (endotracheal tube) under general anesthesia can also cause local airway irritation and edema. Although these airway dimension changes are frequently clinically silent, they can be accurately visualized and quantif...
