title: Comparison of laryngeal mask airway supreme and laryngeal mask airway proseal for laryngopharyngeal trauma and postoperative morbidity in children.
abstract: OBJECTIVE
  Laryngeal mask airway (LMA), which has been used frequently in airway management, can cause laryngopharyngeal injury and morbidity. In this trial, we compare the macroscopic changes on laryngopharyngeal structures and the postoperative laryngopharyngeal morbidity by using LMA supreme with LMA proseal in children.
  
  
  METHODS
  We divided patients into two groups. We inserted size three LMA proseal into the first group and size three LMA supreme into the second group. Before LMA insertion and after LMA removal, we performed direct laryngoscopy on the patients. We compared hyperemia, mucosal injury and blood staining on LMA removal, as well as insertion time, rate of success in gastric tube insertion on the first attempt, nausea, vomiting, and sore throat between the two groups.
  
  
  RESULTS
  We recorded no significant differences between the two groups for mean operation time, sex, age, weight, rate of success in gastric tube insertion on first attempt, nausea, vomiting, sore throat and mucosal injury. Mean insertion time for the LMA proseal group was significantly longer than the LMA supreme group (p = 0.0001). The ratio of blood staining on LMA removal was significantly higher in the LMA proseal group than the LMA supreme group (p = 0.034). The patients with blood staining on LMA removal exhibited significantly more mucosal hyperemia and injury than the patients with clear LMA (p = 0.0001, p = 0.020).
  
  
  CONCLUSIONS
  LMA supreme insertion is faster and easier than LMA proseal and causes less laryngopharyngeal injury than LMA proseal in children.
