Primary Outcome Measures:
  • oropharyngeal leak pressure [ Time Frame: intraoperatively, up to 3 hours ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • total anesthetic and analgesic drug dosages [ Time Frame: intraoperatively and postoperatively, up to 24 hours from end of surgery ] [ Designated as safety issue: No ]
  • pulse oximetry saturation [ Time Frame: intraoperatively and postoperatively, up to 24 hours from end of surgery ] [ Designated as safety issue: Yes ]
  • time to post-anesthetic discharge scoring system (PADSS) > 8 [ Time Frame: in PACU up 72 hours ] [ Designated as safety issue: Yes ]
  • EKG monitoring [ Time Frame: postoperatively up to 72 hours ] [ Designated as safety issue: Yes ]
  • satisfaction of the surgeon (ad hoc questionnaire) [ Time Frame: day 1 ] [ Designated as safety issue: No ]
  • satisfaction of the patient (Iowa Satisfaction with Anesthesia Scale) [ Time Frame: day 1 ] [ Designated as safety issue: No ]
  • gastric distension [ Time Frame: intraoperatively up to 3 hours ] [ Designated as safety issue: Yes ]
  • levels of pain and nausea (Visual Analogue Scale) [ Time Frame: postoperatively up to 24 hours ] [ Designated as safety issue: Yes ]
  • metilen's blue [ Time Frame: before end of surgery up to 3 hours ] [ Designated as safety issue: Yes ]
  • total dosage of analgesic and antihemetic drugs [ Time Frame: intra and postoperatively up to 24 hours ] [ Designated as safety issue: Yes ]

Other Outcome Measures:
  • insertion time [ Time Frame: up to 10 minutes ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 80
Study Start Date: July 2012
Estimated Study Completion Date: July 2014
Estimated Primary Completion Date: July 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: PLMA
Device: ProSeal
Patients will be ventilated with PLMA
Experimental: SLMA
Supreme LMA
Device: Supreme LMA
Patients will be ventilated with SLMA

Detailed Description:
The study will investigate two types of LMA devices endowed of different constructive features. The two devices share common features as far as providing access to the stomach and reducing morbidity of the upper airway. The two device differ in regard to ease of insertion and sealing of the airway and these features are particularly important in the obese patient.
