ClinConnect Summary

This clinical trial is studying whether detaching the breathing circuit during certain types of chest surgery can help reduce the chance of a specific type of breathing tube, called a double-lumen endobronchial tube, becoming misplaced. When patients undergo thoracic surgery, they are sometimes moved from lying flat to lying on their side, which can make the tube shift out of position. The researchers want to find out if disconnecting the breathing circuit during this change in position will lead to fewer problems with the tube, as well as fewer breathing complications after surgery and quicker recovery times.

To be eligible for this trial, patients need to be scheduled for elective surgery that requires a left-sided double-lumen endobronchial tube and must be in good health (classified as ASA I-II). They will be asked to sign a consent form to participate. Once in the operating room, participants will have their vital signs monitored and receive anesthesia before the tube is placed. The researchers will then compare the rates of tube malposition and monitor how well patients recover after the surgery. It's important for potential participants to know that individuals with certain medical conditions, like severe breathing problems or heart issues, will not be eligible for this study.
