SLIPA insertion was facilitated by a jaw thrust (performed by an assistant) in all patients (4).
Fifty-eight patients were enrolled in this study and randomly assigned to the SLIPA or LMA group.
From the isotonic regression analysis and bootstrap distribution, the ECJ0 values of remifentanil for SLIPA and LMA insertions were 0.
Notably, a significant increased in MAP was observed after SLIPA insertion (before insertion 69.
Using the modified up-and-down method, this study shows that the SLIPA requires a lower E[C.
50] value of remifentanil for SLIPA insertion is 32% less than that for LMA.
Changes in PIP, OLP, and the difference between OLP and PIP in the SLIPA group are shown in Figure 1.
The incidence of sore throat was 35% (n=7) in the ETT group and 30% (n=6) in the SLIPA group (P=NS).
While the possibility of these complications is present, Miller et al have demonstrated that, unlike devices with an inflatable cuff in the pharynx, the soft plastic of the SLIPA lines the pharynx and the resilience of the plastic maintains a seal pressure gradient that is supported by the airway pressure itself as the latter increases (17).
In this study, OLP or maximum sealing pressure was measured to evaluate the stability of the SLIPA for airway maintenance.
Lange et al conducted a comparative study of the SLIPA and an LMA in patients undergoing ophthalmic surgery and reported that gastric insufflation occurred more often with the SLIPA, but no regurgitation was observed in either group (19).
The SLIPA is made of stiff plastic material and of fixed shape and causes direct trauma to the oral mucosa.
