A comparison of the effectiveness of the streamlined liner of pharyngeal airway in paralyzed and nonparalyzed patients undergoing gynecological surgery: a randomized trial

Insertion methods comparison for The Streamlined Liner of the Pharynx Airway in children by novice

“…The SLIPA is anatomically pre‐shaped based on the pharyngeal seal, and the chamber is straight and harder than that of other SADs . However, in the sniffing position, the oropharyngeal anatomy is such that the angle between the axis of the mouth (MA) and the pharyngeal axis (PA) is nearly 120° .…”

“…These factors make it difficult to insert the SLIPA and increase the incidence of complications compared to other SADs, especially when inserted by novice doctors (Fig. A) . If the chamber and the oropharyngeal anatomy in the sniffing position have the same angle degree, It could improve insertion success, shorten insertion time and even avoid complications (Figs B and B).Therefore, in the modified method group, the SLIPA was bent 120° at the ‘bridge’ using a Satin‐Slip ® intubating stylet (Mallinckrodt Inc., St. Louis, MO, USA).…”
