“…We assume that relatively larger size SLMA might have been the cause of difficult insertion in those 3 cases. The range of insertion time (TOI) in our study was 11-15 seconds, which is supported by similar findings by Verghese C et al [7] , Cook TM et al [11] and Theiler LG et al [14] . We think that the intelligent design of the fixation tube (FT) along with the elliptical and anatomically shaped semi rigid airway tube of the SLMA facilitated rapid insertion.…”

“…The FT was found, in early pilot studies, to act as a Visual guide to 'correct' size selection, that is after inflation of the cuff to a pressure of 60 cm H 2 O, the FT should be 1.5-2 cm from the upper lip, if the FT is less than this distance the size chosen may be too small and if 3.0 cm from the upper lip the size chosen may be too large. [7] It has been used in adult patients and performed well. [3][4][5] The latest advent of LMA Supreme is its paediatric versions which are now available in four different sizes-1, 1.5, 2, and 2.5 on the basis of body weight.…”

Background: The need of securing the airway quickly in an easier and safer way, especially in paediatric patients still remains a major concern. Newer and safer alternates to endotracheal intubations are being introduced. LMA supreme is one of such advancement in the field of paediatric anaesthesiology. Easy and quick insertion without any introducer, gastric access and high seal pressure are few advantages claimed by LMA Supreme. Apart from a few studies; the safety and efficacy of its paediatric version is yet to be established in Indian paediatric population. Thus, we have conducted an observational study for evaluation of Supreme LMA in paediatric patients. Observational clinical study. Methods: After obtaining approval from institutional ethical committee and consent from patient's attendants, 50 patients of ASA grade I and II, weighing 10-20 kg of either sex undergoing general anaesthesia were included. After induction of anaesthesia and muscle relaxation, the LMA Supreme size 2 was inserted. Number of insertion attempts, ease of insertion, time taken for insertion, hemodynamic responses, ease of NGT insertion and incidence of airway trauma were recorded. Results: In 90% of patients, LMA Supreme was inserted in first attempt. In 94% of cases, insertion was easy. Average time required to insert LMA Supreme was 11.66 ± 0.81 seconds. There were no significant hemodynamic changes noted. In 2 % of cases, airway trauma was observed. Conclusion: LMA supreme emerged as a good alternate airway device. It is quick and easy to insert with fast learning curve with least alteration of hemodynamic status in paediatric population.

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.

“…It has a rigid double-lumen tube with a double aperture design that facilitates the introduction of an orogastric tube to aspirate gastric contents, and it can be inserted without use of introducer devices. In clinical trials, the SLMA has been found comparable with the reusable LMA ProSeal TM (PLMA), 1 with the SLMA having a higher rate of success on first attempt insertion. [2][3][4][5] Previous studies have shown the use of the PLMA and SLMA in non-paralyzed patients, 6 in anesthetized patients with a simulated difficult airway, 7 and in patients undergoing laparoscopy procedures.…”

Background The LMA Supreme TM (SLMA) is a singleuse supraglottic device that provides a good seal for positive pressure ventilation. It has a double aperture design that facilitates the introduction of an orogastric tube to aspirate gastric contents. This observational study evaluated the role of the SLMA in parturients undergoing Cesarean delivery under general anesthesia. Methods Non-obese parturients with at least four hours of fasting and antacid prophylaxis scheduled for uncomplicated Cesarean delivery were recruited from June 2009 through May 2010 at the Quanzhou Women's and Children's Hospital, China. We recorded the number of SLMA insertion attempts, the time to effective ventilation, the incidence of aspiration, and other anesthetic and obstetric outcomes. Postoperatively, we noted the presence of blood on the SLMA, postoperative sore throat, and patient satisfaction. Analysis included comparison of results between parturients having elective and urgent Cesarean delivery. Results We recruited 700 parturients (576 elective, 124 urgent). Mean (standard deviation) body mass index was 25.6 (2.5) kgÁm -2 . All SLMA insertions were successful, with 686 (98%) inserted on first attempt and a time to effective airway of 19.5 (3.9) sec. We maintained ventilation and oxygenation in all parturients with a good seal and there was no evidence of aspiration. Eighteen parturients (2.6%) had blood on the SLMA upon removal, 24 (3.4%) had sore throat, and patient satisfaction was 85 (7)%. These results were similar in elective and urgent cases. Conclusions In a carefully selected group of parturients, the SLMA is a useful alternative to tracheal intubation for Cesarean delivery, providing effective ventilation and a low incidence of side effects or complications.
