“…Its preformed curved shaft consists of a double lumen, i.e., a central lumen for access to the digestive tract encased within a flattened oval-shaped airway lumen for access to the respiratory tract. [10][11][12][13] Other features of the LMA Supreme include a built-in bite block to prevent airway obstruction due to patient bite and moulded fins at the laryngeal outlet to prevent epiglottic obstruction (Fig. 1).…”

“…Insertion times were reported in six studies but were poorly defined in four studies. 11,12,24,28 In studies where the end points of insertion times were defined, they were defined either as time to connection of breathing system 25 or as time to first ventilation. 27 The oropharyngeal leak pressure observed in four studies ranged from 23-39 cm H 2 O.…”

SummarySupraglottic airway devices (SAD) play an important role in the management of patients with difficult airways. Unlike other alternatives to standard tracheal intubation, e.g. videolaryngoscopy or intubation stylets, they enable ventilation even in patients with difficult facemask ventilation and simultaneous use as a conduit for tracheal intubation. Insertion is usually atraumatic, their use is familiar from elective anaesthesia, and compared with tracheal intubation is easier to learn for users with limited experienced in airway management. Use of SADs during difficult airway management is widely recommended in many guidelines for the operating room and in the pre‐hospital setting. Despite numerous studies comparing different SADs in manikins, there are few randomised controlled trials comparing different SADs in patients with difficult airways. Therefore, most safety data come from extended use rather than high quality evidence and claims of efficacy and particularly safety must be interpreted cautiously.

“…It has a modified conical cuff which gives it a high-pressure seal and better performance during mechanical ventilation and a gastric channel running along the posterior midline through the airway tube to facilitate the passage of a gastric tube which allows functional separation of the respiratory and digestive systems. 4,5 The aim of this study was to evaluate the efficacy and superiority of LMA Supreme™, if any compared to endotracheal intubation for positive pressure ventilation with muscle relaxation for intraoperative and postoperative conditions.…”

Comparison of laryngeal mask airway supreme™ versus endotracheal intubation in positive pressure ventilation with muscle relaxant for intraoperative and postoperative conditions

Background: Laryngeal Mask Airways are increasingly being used now a day as an option to endotracheal intubation, as it is less invasive and causes less discomfort in the postoperative period. The aim of this study was to evaluate the clinical use of the laryngeal mask airway SupremeTM in patients undergoing elective gynaecological surgeries under general anaesthesia and compare it with endotracheal intubation.Methods: 60 ASA I and II females, having BMI <30kg.m-2 in the range of 20-50 years of age, scheduled for elective gynaecological surgeries were randomly allocated to one of the two groups according to the device used (LMAS or ETT). Time required for insertion, number of attempts, hemodynamic response to insertion/removal and incidence of immediate and late postoperative complications such as coughing, laryngospasm, sore throat, dysphagia etc. were assessed.Results: Number of attempts for successful insertion was similar but time required for LMA Supreme™ insertion was significantly less (25.40±12.90 versus 33.27±14.82 sec) similarly, time required for nasogastric tube insertion was significantly more in ETT group (30.28±16.22 versus 21.93±12.64 sec). No episode of failed ventilation or hypoxia was recorded. The changes in hemodynamic parameters were significantly higher after endotracheal intubation and during extubation. Incidence of postoperative complications was significantly higher after endotracheal intubation (p<0.05).Conclusions: The LMA Supreme™ is a suitable alternative to endotracheal intubation during general anaesthesia for elective gynaecological surgeries with the added advantage of less hemodynamic response during airway management and lower incidence of postoperative complications.

Prospective Clinical and Fiberoptic Evaluation of the Supreme Laryngeal Mask Airway ™

Abstract: Clinical evaluation of the LMA Supreme showed easy insertion, optimal laryngeal fit, and low airway morbidity. Oropharyngeal leak pressure results were comparable to earlier data from the LMA ProSeal.
