ClinConnect Summary

This clinical trial is looking at how different angles of a disposable tracheal blocker affect the way patients breathe during right lung surgery. The study will be done at three hospitals in China, South Korea, and Serbia, and aims to find the best way to help patients breathe using this device. The trial is currently recruiting participants who are between 18 and 65 years old and are scheduled for right thoracoscopic surgery, which is a type of minimally invasive surgery on the chest.

To be eligible for the study, participants should have good overall health (ASA grades I-III) and no serious history of lung or heart problems. They should also have a good level of oxygen in their blood before surgery. If someone joins the study, they can expect to be randomly placed into one of two groups, each using the tracheal blocker at different angles. This research could help improve breathing techniques during surgery and enhance patient safety.
