Comparison of the GMA-TULIP and I-gel Laryngeal Mask for Airway Management in General Anaesthesia: a Randomized Controlled Trial

The goal of this clinical trial is to learn if GMA-TULIP laryngeal mask willfit well in the right place in participants undergoing trauma surgery in a supine position under general anaesthesia. It will also learn about the convenience, effectiveness and safety of the GMA-TULIP laryngeal mask. The main questions it aims to answer are: Does the GMA-TULIP laryngeal mask exhibit better anatomical alignment? Does the GMA-TULIP laryngeal mask perform effectively in trauma surgery patients in a supine position under general anaesthesia? Researchers will compare with the i-gel laryngeal mask (a device already popular among anaesthetists) to see if the GMA-TULIP laryngeal mask works to have a good performance in general anaesthesia. Participants will describe feelings immediately after anesthesia， 1 hour later and 24 hours later.
