“…This said, in our trial the Singularity TM Air has shown some important disadvantages as compared to the Ambu ® Aura Gain TM . A first-attempt insertion rate of 68% is considerably lower than the 94% for the Ambu ® Aura Gain TM and is certainly unsatisfactory when compared to other studies [25,26]. A possible explanation for this may be found in the soft tip of the Singularity TM Air.…”

Background: This randomised crossover mannequin study aimed to compare the insertion time for the newly developed SingularityTM Air and the Ambu® AuraGainTM. The SingularityTM Air includes a bendable tube in order to allow optimal passform. Methods: Fifty anaesthetists with a minimum of 100 supraglottic airway device insertions were recruited and randomly assigned to start either with the SingularityTM Air or with the Ambu® AuraGainTM. Participants watched a tutorial video the day before the assessment and received a standardized introduction immediately before the assessment. The primary outcome was the time for successful insertion. Secondary parameters were the overall insertion success rate, the numbers of insertion attempts (maximum three), the glottic view through a flexible bronchoscope, and the success rate for gastric tube insertion. Results: Fifty participants were eventually recruited and randomly assigned to insert both devices according to the randomization. The insertion time was 24 s for SingularityTM Air as compared to 20 s for Ambu® AuraGainTM (p < 0.001). Overall insertion rate was 92% for the SingularityTM Air as compared to 100% for the Ambu® AuraGainTM (p could not be derived as one variable is a constant). The primary insertion success rate was better for the Ambu® AuraGainTM than for the SingularityTM Air (94% versus 68%; p: 0.002, respectively). Conclusion: The time for successful insertion and the insertion success rate for the newly developed SingularityTM Air is inferior to that for the Ambu® AuraGainTM.

“…Still others feature higher device conditioning stiffness and friction coefficients, have a thicker cuff and/or a higher cuff profile, for example, LMA ® -ProSeal™ ,a , 12 LMA ® -Protector™ ,b , 13 Baska-Mask, 14 streamlined liner of the pharynx airway (SLIPA). 15 Therefore, use of some SGDs requires more training, 16,17 and additional adjunct devices may be necessary, such as, for example, an introducer, a stylet, a gum elastic bougie, a gastric tube, [18][19][20] while others can be readily inserted by novices. 21,22 Some SGDs have a preshaped, anatomically curved tube following the normal oropharynx anatomy, or include a fixation tab.…”

Correct placement of supraglottic airway devices (SGDs) is crucial for patient safety and of prime concern of anesthesiologists who want to provide effective and efficient airway management to their patients undergoing surgery or procedures requiring anesthesia care. In the majority of cases, blind insertion of SGDs results in less-than-optimal anatomical and functional positioning of the airway devices. Malpositioning can cause clinical malfunction and result in interference with gas exchange, loss-of-airway, gastric inflation, and aspiration of gastric contents. A close match is needed between the shape and profile of SGDs and the laryngeal inlet. An adequate first seal (with the respiratory tract) and a good fit at the second seal of the distal cuff and the gastrointestinal tract are most desirable. Vision-guided insertion techniques are ideal and should be the way forward. This article recommends the use of third-generation vision-incorporated-video SGDs, which allow for direct visualization of the insertion process, corrective maneuvers, and, when necessary, insertion of a nasogastric tube (NGT) and/or endotracheal tube (ETT) intubation. A videoscope embedded within the SGD allows a visual check of the glottis opening and position of the epiglottis. This design affords the benefit of confirming and/or correcting a SGD’s position in the midline and rotation in the sagittal plane. The first clinically available video laryngeal mask airways (VLMAs) and multiple prototypes are being tested and used in anesthesia. Existing VLMAs are still not perfect, and further improvements are recommended. Additional modifications in multicamera technology, to obtain a panoramic view of the SGD sitting correctly in the hypopharynx and to prove that correct sizes have been used, are in the process of production. Ultimately, any device inserted orally—SGD, ETT, NGT, temperature probe, transesophageal scope, neural integrity monitor (NIM) tubes—could benefit from correct vision-guided positioning. VLMAs also allow for automatic recording, which can be documented in clinical records of patients, and could be valuable during teaching and research, with potential value in case of legal defence (with an airway incident). If difficulties occur with the airway, documentation in the patient’s file may help future anesthesiologists to better understand the real-time problems. Both manufacturers and designers of SGDs may learn from optimally positioned SGDs to improve the design of these airway devices.

Introduction: difficult airway is that clinical situation in which a conventionally trained anesthesiologist experiences difficulty in ventilation with a face mask, in endotracheal intubation or both. In this review article we will focus on emergency intubation. Objective: to systematically review the current state of knowledge and clinical evidence related to the management of difficult airways in emergency intubation. Material and methods: a systematic review was carried out in PubMed, Cochrane data base, EBSCO and OVID; the terms: difficult airway management and emergency intubation; only clinical trials and scientific research reports were analyzed. Results: the search yielded 356 results, of which systematic review studies, meta-analysis, opinion-based articles, case reports, letters to the editor were excluded; which gave us 128 articles, after they were analyzed; it was also sought to analyze articles from different areas of medical research; 21 articles were selected to be analyzed in this systematic review. Conclusions: unexpectedly, the majority of the reviewed articles conclude that regardless of the intubation protocol or the tools used, the aspect that plays a decisive role in the management of the difficult airway is the experience and previous preparation of the anesthesiologist.
