ClinConnect Summary

This clinical trial is studying three different types of laryngeal masks used during surgeries where patients are lying on their sides and under general anesthesia. The goal is to compare how well these masks work and how safe they are, particularly focusing on something called oropharyngeal leak pressure, which relates to how well air is kept in the lungs during surgery. This research aims to help doctors choose the best type of laryngeal mask for these specific surgeries.

To participate in this study, you need to be between 18 and 80 years old, have a body mass index (BMI) of less than 28, and be scheduled for a surgery that lasts less than 3 hours while lying on your side. You should also be in good health according to the American Society of Anesthesiologists guidelines (grades I-III). Participants will need to sign a consent form and be able to understand the study process. If you have certain medical conditions or difficulties that might affect your participation, you may not be eligible. Overall, this trial is an important step in improving the safety and effectiveness of anesthesia practices during specific surgeries.
