A comparative study of vital capacity breath inhalation with sevoflurane versus intravenous propofol to aid laryngeal mask airway insertion in adults

Background: Laryngeal mask airway has already gained widespread acceptance as an alternative airway device and conduit for endotracheal intubation. Insertion of this Supraglottic Airway Device (SAD) to provide and maintain a seal around the laryngeal inlet for spontaneous ventilation as well as modest level of positive pressure ventilation requires a sufficient depth of anaesthesia and depression of airway reflexes to avoid adverse reactions like gagging, coughing, head and limb movements etc. This study was conducted with the intent to compare Vital Capacity Breath (VCB) inhalation with 8% sevoflurane versus intravenous (IV) propofol for quality and ease of insertion of Laryngeal Mask Airway (LMA) and associated complications Methods: In this prospective, randomized study, 80 adult patients of ASA physical status I and II aged between 20 to 50 years, body weight 0.05).
