title: [Comparison of efficacy for laryngeal mask airway-Supreme(TM) versus common laryngeal mask airway in children].
abstract: OBJECTIVE
  To compare the efficacy of laryngeal mask airway-Supreme(TM) versus common laryngeal mask airway in children with general anesthesia.
  
  
  METHODS
  With local research ethics committee's approval and written informed parental consent, 100 children were randomly divided into groups L (size 2.0 common laryngeal mask airway) and S (size 2.0 laryngeal mask airway-Supreme(TM)) according to random number (n = 50 each). After anesthesia induction, a common laryngeal mask airway or laryngeal mask airway-Supreme(TM) was inserted and mechanically ventilated. Time and ease for insertion, insertion success rate, airway leak pressure, success rate and ease of disposal sputum collecting tube insertion in group S, quality of airway during anesthetic maintenance, abdominal circumference changes and complications within 24 h post-operation were measured.
  
  
  RESULTS
  Compared with group L, abdominal circumference increased less in group S (0.90 ± 0.35 vs 0.43 ± 0.18 cm, n = 46, P < 0.01). No significant inter-group differences existed for other measurements. Disposal sputum collecting tube was successfully placed in group S(100%).
  
  
  CONCLUSIONS
  In children with mechanical ventilation, laryngeal mask airway-Supreme(TM) can be effectively applied to maintain a good airway. And the incidence of gastric insufflation is lower. It is particularly useful for those requiring evacuation of gastric contents during general anesthesia.
