“…The main finding was that the time for successful insertion and the insertion success rate for the Singularity TM Air was significantly inferior compared to the Ambu ® Aura Gain TM . The insertion success rate and the insertion time for the Ambu ® Aura Gain TM laryngeal mask are comparable to those in reported previous mannequin-based studies [21,22]. To date, there are no comparable data for the Singularity TM Air as this is the first controlled trial.…”

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.

BackgroundA laryngeal tube is often used as an alternative to intubation with direct laryngoscopy during cardiopulmonary resuscitation. However, in a study with piglets undergoing simulated cardiac arrest, reduced carotid artery blood flow was associated with the insertion of different supraglottic airway devices, such as a laryngeal tube. Limited by its construction, secondary tracheal intubation through a laryngeal tube was difficult or impossible in contrast to a second generation laryngeal mask. The new disposable intubating laryngeal tube with suction (iLTS-D®) seems to facilitate tracheal intubation. We hypothesized that iLTS-D, when inflated to the recommended air volume, does not reduce cerebral oxygenation in patients with cardiovascular diseases undergoing elective cardiac surgery.MethodsThis single-center prospective, controlled observational study was approved by the local ethics committee (Ethical Committee No. 2018-13716). Forty adult patients undergoing elective cardiac surgery requiring tracheal intubation were included in this study. The exclusion criteria were age <18 years and a high risk of aspiration, inability to consent, height <155 cm, or pregnancy. Prior to insufflation and deflation of the cuffs, we performed cerebral oximetry via near-infrared spectroscopy. The primary outcome was a significant reduction in NIRS in the context of the preinduction baseline value after inflation of the cuffs with the recommended air volume, defined as a ≥25% decrease from baseline or an absolute value ≤ 50%. The secondary endpoints were differences in time points, insertion success rates, and complications.ResultsThere was no significant reduction in cerebral oximetry after inflation with the recommended cuff volume and an initially measured cuff pressure of >120 cmH2O. Overall, tracheal intubation was achieved in a median of 20 s [interquartile range 15-23 s] and enabled sufficient ventilation and tracheal intubation through the iLTS-D in all patients. Traces of blood on the cuffs (after removing the iLTS-D) and a sore throat (evaluated 2 h after removing the tracheal tube) were observed in one patient.ConclusionOur results showed no association between the insertion of the iLTS-D and reduced cerebral oxygenation in patients undergoing elective cardiac surgery.Trial registrationClinicalTrials.gov, NCT03942809.

Supraglotické pomůcky patří v současnosti do rutinní klinické praxe pro zajištění dýchacích cest u elektivních operačních výkonů, ale i k tracheální intubaci nebo oxygenaci při obtížném zajištění dýchacích cest. Dalšími indikacemi jsou použití v urgentní a intenzivní medicíně i v přednemocniční péči. Zvýšené požadavky na bezpečnost, rozšíření indikací a použití v akutních situacích vedly k vývoji nových pomůcek. Univerzální pomůcky typu Ambu AuraGain, LMA Protector nebo i -gel Plus umožňují použití při elektivních operacích i pro následnou fibrooptickou tracheální intubaci. Další pomůcky jako LMA Guardian byly vyvinuty ke zvýšení těsnících tlaků, zatímco Baska maska má samoregulovatelný tlak v manžetě, který by měl teoreticky snížit četnost pooperačních komplikací. LMA Gastro byla vyvinuta pro endoskopické výkony na jícnu a žaludku, iLTS a TotalTrack VLM jako speciální pomůcky pro obtížné zajištění dýchacích cest.
