BACKGROUND: This study aimed to evaluate the applicability of Cobra perilaryngeal airway (Cobra @entity1989   ) for @entity28 @entity1 under general anesthesia and also to compare the results with those of classic laryngeal mask airway (LMA   ). MATERIALS AND METHODS: Seventy-three overweight and @entity28 @entity1 were included in this study. The @entity1 were randomly assigned to LMA    or Cobra @entity1989    groups. Time required for intubation, successful intubation attempt, airway sealing pressure and incidence of complications including blood staining, sore throat and @entity1282 were assessed and noted. RESULTS: Thirty-six and 37 @entity1 were randomly allocated to LMA    and Cobra @entity1989    groups, respectively. Most @entity1 were males and had Mallampati Class II airway in both groups. The first attempt and overall insertion success for Cobra @entity1989    was significantly higher compared to LMA (P<0.05). Airway insertion was more successful (P = 0.027; 94% vs. 77%) with Cobra @entity1989   . Insertion times were similar with Cobra @entity1989    and LMA    (Cobra @entity1989   , 29.94  16.35s; LMA   , 27.00  7.88s). The oropharyngeal leak pressure in the Cobra @entity1989    group (24.80  0.90 H2O) was significantly higher than that in LMA    group (19  1 @entity4358 , p<0.001). Sore throat was more frequent in the LMA    group although it did not reach statistical significance (Fisher's exact test, P = 0.33). Blood staining on airway tube was seen in both groups with a higher incidence in the Cobra @entity1989    group (Fisher's Exact test, P = 0.02). Incidence of @entity1282 was not different between the two groups. CONCLUSION: CobraPLA    was found to be safe with low complications. It provided better airway sealing with high rate of the first insertion success for use in @entity28 and overweight @entity1 . This study recommends the use of CobraPLA    as a rescue device in emergency situations for @entity28 and overweight @entity1 .
