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

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.

Inclusion Criteria:

18 years old ≤ age ≤ 70 years old. Patients undergoing trauma surgery in a supine position under general anesthesia.

18 kg/m2 ≤ BMI ≤ 35 kg/m2. American Society of Anesthesiologists (ASA) grades I-III. Can understand the research process and the use of pain scales. Clear understanding and voluntary participation in the study, signing of informed consent form.

Exclusion Criteria:

Patients with known or predicted difficult airways. High risk of reflux or aspiration (e.g., gastroesophageal reflux disease patients).

Individuals with active upper respiratory tract infections. Cervical related diseases or surgical history. Preoperative sore throat or previous sore throat or hoarseness. Patients with oral and maxillofacial trauma or fractures. Other reasons why researchers believe it is not appropriate to participate in the experiment.
