“…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.…”

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.

“…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. 8,9 More recent studies and case reports have shown that it is effective in providing ventilation and oxygenation in challenging cases, such as the morbidly obese patients, 10 patients in the prone position, 11,12 and those who have suffered from multiple trauma.…”

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.

“…Six of the studies compared the LMA Supreme with the LMA Proseal. 10,[13][14][15][16][17] The remaining studies compared the LMA Supreme with the LMA Classic, 23 i-gel, [18][19][20] facemask, 21 or endotracheal tube. 22 In the six RCTs comparing the LMA Supreme with the LMA Proseal, 418 patients were identified and 295 (70%) of those were female.…”
