The time taken to provide an effective airway , the number of insertion attempts , fibreoptic position of the airway tube and frequency of mucosal trauma were similar , but oropharyngeal leak pressure was higher ( 33 vs 26 cm H ( 2 ) O , P < 0.0001 ) and gastric insufflation less common ( 0 vs 6 % , P < 0.01 ) for the PLMA .
