ClinConnect Summary

This clinical trial is studying how to improve breathing during and after abdominal laparoscopic surgery, a common type of minimally invasive surgery. Researchers want to find out if using special breathing techniques, like recruitment maneuvers (which help open up the lungs) and a method called electrical impedance tomography (EIT) to personalize breathing settings, can lead to better lung function and recovery compared to standard ventilation methods. This is important because some patients may experience breathing difficulties after surgery, which can affect their recovery.

To participate in this trial, you need to be over 18 years old and scheduled for abdominal laparoscopic surgery. You should also have a higher risk of breathing problems after surgery based on a specific scoring system. However, not everyone can join; for instance, those with severe lung diseases or certain medical devices may be excluded. If you decide to participate, you'll receive personalized care to help improve your lung health during surgery, and you’ll be closely monitored to see how these techniques work for you.
