ClinConnect Summary

This clinical trial is investigating whether increased pressure in the abdomen during laparoscopic cholecystectomy, a type of surgery to remove the gallbladder, can lead to swelling in the airway. Researchers want to find out if this swelling, known as airway edema, could make it more challenging to breathe after the surgery. To do this, they will look at two groups of patients: one group will have low pressure in the abdomen during the surgery, while the other group will have standard pressure. They will use ultrasound to measure changes in the airway before and after the procedure.

To participate in this study, patients need to be between 18 and 65 years old, have a healthy body weight, and be scheduled for this specific surgery. However, individuals with certain health conditions, such as a history of breathing difficulties or severe heart and lung diseases, will not be eligible. Participants can expect to undergo routine monitoring and measurements during their surgery, and their results will help doctors understand more about the risks associated with airway swelling after surgery. This research aims to improve safety for patients undergoing laparoscopic cholecystectomy in the future.
