Summary

To compare a polyvinyl chloride tube with a wire-reinforced tube for tracheal intubation through the SaCoVLM video laryngeal mask airway, to observe the success rate of intubation and the incidence of postoperative adverse reactions, and to explore the best type of endotracheal tube through the SaCoVLM video laryngeal mask airway, so as to provide reference for its clinical application.

Detailed description

1. At present, there are few studies on intubation through SaCoVLM video laryngeal mask airway. It is proposed that endotracheal intubation through SaCoVLM video laryngeal mask airway is to verify its feasibility. 2. The purpose is to explore the best type of endotracheal tube by observing the success rate of intubation through SaCoVLM video laryngeal mask airway and the incidence of postoperative adverse reactions. 3. By observing the hemodynamic changes of the polyvinyl chloride tubes and the wire-reinforced tube during intubation through SaCoVLM video laryngeal mask airway , the effects of the two tracheal tubes on the hemodynamics of patients were compared. 4. By observing the optimized operation which can improve the success rate of tracheal intubation in the experiment, it can be better applied in clinical practice.

• Laparoscopic Surgery

Interventions

Type	Name	Description
PROCEDURE	Polyvinyl Chloride Tube group	The anaesthesiologist will perform a visual screen for the SaCoVLM glottic exposure grade after the SaCoVLM is successfully inserted. The SaCoVLM glottic exposure grade was referred to the endoscopic view grading system. If the SaCoVLM glottic exposure grade is 1 or 2, a lubricated tracheal tube will be inserted in a conventional manner with the curvature of the tracheal tube aligned along the intrinsic curvature of the SaCoVLM. The passage of the tracheal tube into the glottis will be visualised. If there is a discrepancy in the alignment of the tracheal tube exiting from the SaCoVLM and the glottis that will prevent the passage of the tracheal tube into the glottis, the tracheal tube will be withdrawn and manipulations (rotation of the tracheal tube or up/down manoeuvre) will be performed in an attempt to align the glottis and tracheal tube tip to facilitate intubation. Such manoeuvres, if performed, will be recorded.
