Abstract :

The present study was designed to evaluate the performance details of the Classic laryngeal mask airway and ProSeal laryngeal mask airway in anesthetized, paralysed patients in terms of ease of insertion, oro–pharyngeal seal pressure, fiberoptic position of airway tube and complication rates. Seventy patients of ASA grade I and II of either sex, aged between 20–50 years undergoing minor peripheral surgeries in the supine position were selected. Patients were randomly allocated to receive either Classic LMA or Proseal LMA for airway management after induction with Fentanyl 2 �g/kg, Propofol 2.5 mg/kg and neuromuscular blockade with atracurium 0.5mg/kg. Anaesthesia was further maintained with sevoflurane 1–3% in 50% oxygen and air. The study showed that Classic LMA takes less time for insertion, achieves an unobstructed view of the glottis more frequently but achieves a poorer seal with the pharynx. The ProSeal LMA takes longer time for insertion but is capable of achieving a more effective seal and also facilitates gastric tube placement.
