Comparison of Five 2nd-Generation Supraglottic Airway Devices for Airway Management Performed by Novice Military Operators

Objectives. Five different second-generation supraglottic airway devices, ProSeal LMA, Supreme LMA, i-gel, SLIPA, and Laryngeal Tube Suction-D, were studied. Operators were inexperienced users with a military background, combat lifesavers, nurses, and physicians.Methods. This was a prospective, randomized, single-blinded study. Devices were inserted in the operating room in low light conditions after induction of general anesthesia. Primary outcome was successful insertion on the first attempt while secondary aims were insertion time, number of attempts, oropharyngeal seal pressure, ease of insertion, fibre optic position of device, efficacy of ventilation, and intraoperative trauma or regurgitation of gastric contents.Results. In total, 505 patients were studied. First-attempt insertion success rate was higher in the Supreme LMA (96%), i-gel (87.9%), and ProSeal LMA (85.9%) groups than in the Laryngeal Tube Suction-D (80.6%) and SLIPA (69.4%) groups. Insertion time was shortest in the Supreme LMA (70.4 ± 32.5 s) and i-gel (74.4 ± 41.1 s) groups (p<0.001). Oropharyngeal seal pressures were higher in the Laryngeal Tube Suction-D and ProSeal LMA groups than in other three devices.Conclusions. Most study parameters for the Supreme LMA and i-gel were found to be superior to the other three tested supraglottic airway devices when inserted by novice military operators.

AbstractNumerous supraglottic airway device (SADs) have been designed for adults; however, their relative efficacy, indicated by parameters such as adequacy of sealing, ease of application, and postinsertion complications, remains unclear. We conducted a systematic review and network meta-analysis to evaluate the efficacy of various SADs. We searched electronic databases for randomized controlled trials comparing at least two types of SADs published before December 2019. The primary outcomes were oropharyngeal leak pressure (OLP), risk of first-attempt insertion failure, and postoperative sore throat rate (POST). We included 108 studies (n = 10,645) comparing 17 types of SAD. The Proseal laryngeal mask airway (LMA), the I-gel supraglottic airway, the Supreme LMA, the Streamlined Liner of the Pharynx Airway, the SoftSeal, the Cobra Perilaryngeal Airway, the Air-Q, the Laryngeal Tube, the Laryngeal Tube Suction II, the Laryngeal Tube Suction Disposable, AuraGain, and Protector had significantly higher OLP (mean difference ranging from 3.98 to 9.18 cmH2O) compared with that of a classic LMA (C-LMA). The Protector exhibited the highest OLP and was ranked first. All SADs had a similar likelihood of first-attempt insertion failure and POST compared with the C-LMA. Our findings indicate that the Protector may be the best SAD because it has the highest OLP.Systematic review registration PROSPERO: CRD42017065273.

Objective: The aim of this was to compare the Baska® mask and the I-gel® airway in paralyzed patients during general anaesthesia in terms of clinical performance, the risk of aspiration, and intraoperative and postoperative characteristics. Material and Methods: The two devices were compared in 100 paralyzed anesthetized adult patients. Primary outcomes of the study were to evaluate the characteristics of the airway devices within respect to the success of first insertion attempt, the insertion time, the ease of insertion, leak volume, and peak airway pressure. The blood staining on the mask, and the presence of gastric reflux or sore throat two hours postoperatively were evaluated. Hemodynamics, end-tidal CO2 and the peripheral oxygen saturation measurements were secondary outcomes. Results: No statistically significant difference was observed between the groups in the criteria of first attempt success rate, ease of insertion, blood staining upon removal of the masks, gastric regurgitation, or sore throat two hours after the procedure. The insertion time was significantly longer for the Baska® mask compared with the I-gel® airway. The leak volume was significantly higher in the Baska® mask patients throughout the surgical procedure. The heart rate and mean arterial pressure measurements were significantly higher in the Baska® mask patients. Conclusions: Both the Baska® mask and the I-gel ® device can be used effectively for selected paralyzed patients under general anaesthesia. The insertion time was significantly longer for the Baska® mask compared with the I-gel® device.
