Background: The LMA-Classic is a first generation supraglottic airway device, with largest evidence base for efficacy and safety, and is considered benchmark against which newer LMA are judged. The LMA-ProSeal is a second generation supraglottic airway device with modified cuff and drainage tube, designed for better seal with both the respiratory and gastrointestinal tracts, notwithstanding the access to the alimentary tract. This study compared is planned to compare efficacy of the LMA-Classic and LMA-ProSeal in children undergoing elective surgery under general anaesthesia.
Materials and method: This comparative study was done during the period of 01–Jan – 2018 to 30–aug–2018 in Viswa Bharthi Institute of Medical Sciences in the Department of Anaesthesiology with 40 ASA 1-2 children undergoing circumcision, herniotomy and orchiopexy were included. The patients were randomly assigned to size 2.5 LMA-ProSeal or 2.5 LMA-Classic groups for airway management. We assessed success rates at first attempt of insertion, airway sealing pressure, maintenance of airway and postoperative complications.
Results: There was no statistical difference between two groups for the success rates at first attempt of insertion and maintenance of airway but sealing pressure was significantly high in the LMA-ProSeal group. Regarding postoperative complication like injury to lip-teeth-tongue, blood staining and cough or laryngospasm were also not significant.
Conclusion: the ease of insertion, maintenance of airway and risk of injury are similar between the LMA-ProSeal and the LMA-Classic in children.
