What this Trial Is About
This study aims to compare the new-generation GMA laryngeal mask airway (LMA) with the traditional inflatable LMA in patients undergoing elective surgery under general anesthesia. The primary objectives are to evaluate the safety, effectiveness, stability, ease of use, and patient comfort of the GMA LMA, providing practical guidance for clinical airway management. Additionally, this research will analyze the anatomical positioning and sealing mechanism of the LMA to identify factors influencing proper alignment and airway sealing. The findings may contribute to future improvements in LMA design, enhancing patient safety and procedural success. This study is designed for healthcare providers, anesthesiologists, and researchers seeking evidence-based recommendations for LMA selection in clinical practice. Participation involves standard anesthesia procedures with close monitoring to ensure patient safety.
