ClinConnect Summary

This clinical trial is studying how different methods of breathing support during anesthesia can affect the lungs of healthy children aged 1 to 6 who are having elective circumcisions. The researchers want to see if using a face mask, a laryngeal mask, or a special kind of laryngeal mask with pressure support makes a difference in how well air spreads throughout the lungs during surgery. They will use a special device called electrical impedance tomography to measure how well the lungs are ventilated, which can help reduce the risk of breathing problems after surgery.

To participate in this study, children must be between 1 and 6 years old and be scheduled for an elective circumcision, with no history of lung or heart conditions. Throughout the process, parents can expect standard monitoring of their child's vital signs and a series of lung measurements taken at different times: before anesthesia, right after it's given, after surgery, and before discharge. It's also important to note that some children might not be eligible to participate for various medical reasons.
