title: Comparative Study of Two Laryngeal Mask Airways: Proseal Laryngeal Mask Airway and Supreme Laryngeal Mask Airway in Anesthetized Paralyzed Adults Undergoing Elective Surgery.
abstract: BACKGROUND
  Supraglottic airway devices can act as an alternative to endotracheal intubation in both normal and difficult airway. LMA Proseal (P-LMA) and LMA Supreme (S-LMA) alongwith acting as effective ventilating device, provide port for gastric drainage.
  
  
  OBJECTIVE
  The objective of this study was to compare the two devices for effective ventilation and complications.
  
  
  METHODS
  A prospective, randomized, single-blinded study was conducted in a tertiary care teaching hospital. Methods: 100 patients of ASA grade I-II undergoing elective surgery under general anaesthesia were included after ethical committee clearance and written consent. Patients were randomly allocated size 4 P-LMA (Group P) or S-LMA (Group S) (50 patients in each group). Insertion attempt, insertion time, oropharyngeal leak pressure (OLP) and complications were compared.
  
  
  RESULTS
  There was no difference demographically. The first insertion attempts were successful in 92% with P-LMA and 96% with S-LMA. Insertion time was faster in S-LMA. The mean OLP was 24.04 cmH2O in GroupPand 20.05 cmH2O in Group S. Complications were cough, mild blood staining.
  
  
  CONCLUSIONS
  Both can act as an effective ventilatory devices. But where LMA Proseal provides a more effective glottic seal by having a greater OLP, single use LMA Supreme provides acceptable glottic seal with easier and faster insertion, therefore, it can be accepted as better alternative to LMA Proseal.
