Background: Supreme laryngeal mask airway (SLMA) and I-gel airway devices are second generation supraglottic airway devices (SAD) and are good alternatives to intubation during surgeries. The study was conducted with the objective to compare two supraglottic airway devices for ease of insertion, number of attempts of insertion, hemodynamic changes, incidence of adverse effects like regurgitation, lip and dental trauma and post-operative sore throat, dysphagia or hoarseness. Methods: This study was conducted at Topiwala National Medical College and BYL Nair hospital, Mumbai. 80 patients of ASA class 1 and 2 with Mallampati grading 1 and 2, between age group of 18-60 years and with BMI <28kg/m 2 were selected for the study. After induction of anesthesia for all the patients, one of SAD (SLMA or I-gel) was inserted randomly and accordingly they are divided into two groups consisting of 40 in each. Insertion parameters, hemodynamic and respiratory parameters were noted. Patients were also observed for any complications for 1 hour and 24 hours postoperatively. Results: Both groups were compared in terms of demographic characteristics, insertion parameters, hemodynamic and respiratory parameters and found no statistically significant differences between them (p>0.05). Postoperatively no significant complications were observed in terms of dental injury, laryngospasm. Complication like sore throat after 1 hour and after 24 hours was comparatively more in I-gel group but difference was not significant at 1 hr (p>0.05). Dysphagia was reported more in SLMA group (8 cases) than I-gel group (1 case) at one hour and the difference was statistically significant (p=0.013). Conclusions: SLMA and I-GEL are better airway management option for patients undergoing short surgical procedures under general anaesthesia.Keywords: Efficacy, I-gel, Safety, Supraglottic airway devices, SLMA DOI: http://dx.doi.org/10.18203/2320-6012.ijrms20175437Samel SA et al.

It has integral bite block and a tab for adhesive fixation of the device. Fixation tab is rectangular structure moulded on to the manifold at right angles and projects over the patient's upper lip. It is designed to facilitate easy insertion and fixation of the SLMA, after insertion and inflation of its cuff. 3 The I-gel is a truly unique latex free SAD. The shape, softness and contours accurately mirror the peri-laryngeal anatomy to create the perfect fit and no cuff inflation is required. I-Gel provides controlled ventilation and spontaneous breathing during anaesthesia and it allows easy recognition of gastric content and passage of drain tube and suctioning and venting. 4 Many studies have been conducted regarding the safety and efficacy of SLMA and I-gel in various situations. [4][5][6][7] But still there is a need to prove their safety and efficiency in short surgical procedures. Henc...

Study Objective:Various randomized controlled trials and a meta-analysis have compared i-gel™ and laryngeal mask airway Supreme™ (LMA-S™) in adult patients and found that both the devices provided equivalent oropharyngeal leak pressure (OLP). However, no randomized controlled trial has compared air-Q™ with i-gel™ and LMA-S™ in adult patient. Hence, we designed this study to compare air-Q™ with LMA-S™ and i-gel™ in adult patients.Materials and Methods:A total of 75 adult patients of the American Society of Anesthesiologists physical status I/II of both sexes, between 18 and 60 years, were included in this prospective randomized controlled trial conducted in a tertiary care center. Randomization of patients was done in three equal groups according to the insertion of supraglottic airway device by a computer-generated random number sequence: group air-Q™ (n = 25), group i-gel™ (n = 25), and group LMA-S™ (n = 25). Primary outcome of this study was OLP. We also recorded time for successful placement of device, ease of device insertion, number of attempts to insert device, and ease of gastric tube insertion along with postoperative complications.Results:The mean ± standard deviation OLP of air-Q™, i-gel™, and LMA-S™ was 26.13 ± 4.957 cm, 23.75 ± 5.439 cm, and 24.80 ± 4.78 cm H2O (P = 0.279). The first insertion success rate for air-Q™, i-gel™, and LMA-S™ was 80%, 76%, and 92%, respectively (P = 0.353). The insertion time of air-Q™, i-gel™, and LMA-S™ was 20.6 ± 4.4, 14.8 ± 5.4, and 15.2 ± 4.7 s, respectively (P = 0.000). Time taken for air-Q™ insertion was significantly higher than time taken for i-gel™ (mean difference 5.8 s, P < 0.0001) and LMA-S™ (mean difference 5.4 s, P = 0.0001) insertion. Postoperative complications were similar with all three devices.Conclusions:We concluded that air-Q™, i-gel™, and LMA-S™ were equally efficacious in terms of routine airway management in adult patients with normal airway anatomy.

“…The special anatomically shape and rigidity of LMA-S makes it a perfect device for an easy insertion, as it has been proved by several authors when comparing LMA-S to other devices, so it explains our results (14,15,17,18).…”

Objectives : LMA Supreme® (LMA-S) mask is one of the most used and proved supraglottic airway devices (SADs) for laparoscopy. The Baska® mask is a relatively new SAD with an inbuilt drain channel and just a limited experience has been reported with this device. We compared these two SADs with regard to safety, efficacy, ease of use and incidence of adverse events for laparoscopic cholecystectomy. Methods : Prospective, randomized, controlled study of two groups of 40 patients each, undergoing elective laparoscopic cholecystectomy. After induction of general anesthesia (maintained with 5% desflurane in 50% oxygen and air, remifentanil 0.2-0.5 μg kg-1 min-1 and rocuronium 0.6 mg kg-1), we evaluated, success rates, speed of insertion, ease of insertion of the drain tube, leak pressure, tidal volume and airway pressures (peak pressure and plateau pressure). We also recorded intraoperative adverse events and postoperative oropharyngeal discomfort. Results : Success rate on first attempt insertion was higher for the LMA-S group than the Baska® mask group (97.5% and 60% respectively; p < 0.001). There was no difference in the median time taken for the insertion between groups (p = 0.93). Ease of insertion of the drain tube differed significantly and it was slightly easy inserted in the LMA-S group (p = 0.04). Leak pressure was similar between the groups (p = 0.61) and it was consistent with a similar tidal volume achieved (p = 0.10). Both devices showed equal sore throat scoring at 2h postoperatively (p = 0.24). Conclusions : We found that LMA-S was an easier device to insert than the Baska® mask, showing a better success rate on first attempt insertion. Insertion of the drain tube was also easier for the LMA-S group. Seal pressure and tidal volume achieved were similar between groups. Complication rates and postoperative OPD scoring are comparable for both devices.
