“…Studies comparing the LMA-Unique TM and the Portex Soft Seal TM with the LMA Classic have demonstrated that these single-use devices have similar clinical effectiveness and may be acceptable alternatives [6][7][8]. The Ambu Ò AuraOnce TM Laryngeal Mask (Ambu A ⁄ S, Ballerup, Denmark) is claimed to have advantages over competitors.…”

SummarySingle-use supraglottic airway devices are now available and are intended to be comparable with the reusable LMA Classic TM laryngeal mask airway. We performed a randomised cross-over study comparing the Ambu Ò AuraOnce TM Laryngeal Mask with the LMA Classic. Fifty patients participated in the trial. Success rates for insertion at the first attempt were similar (92% with the Ambu and 84% with the LMA Classic; p ¼ 0.22). The volumes of air required to inflate the cuff to produce a seal were similar, but the cuff pressure was lower for the Ambu Laryngeal (73-93 [26-97]) mm for the ) for the LMA Classic (p ¼ 0.017). Complications were similar in both groups. We suggest that the disposable Ambu Laryngeal Mask is an acceptable alternative to the reusable LMA Classic.

“…Theoretically, the wider shaft and absence of cross-bars might make tracheal intubation through this device easier than through the CLMA. Van Zundert et al have recently studied the ease of placement of the PLMA and found it to be similar to the CLMA [6]. Although they used the fibrescope to establish the view of the vocal cords through the PLMA, they did not assess the ease of fibreoptic-assisted tracheal intubation through the PLMA.…”

SummaryWe compared times to intubate the trachea orally and success rates using two fibreoptically assisted techniques in 42 healthy patients with normal airways using (a) a 6.0‐mm nasal RAE tracheal tube passed through a classic laryngeal mask airway (CLMA group) or (b) a 6.0‐mm nasal RAE tracheal tube passed through a new disposable Portex Soft Seal laryngeal mask airway (PLMA group). The mean (SD) total intubation times were 82 (14) and 80 (17) s, respectively (p = 0.55). The success rates for intubation at the first attempt were similar (17/21 in the CLMA vs. 16/21 in the PLMA group; p = 0.50). We conclude that there is no clinically significant difference between the times to intubate the trachea or success rates using these two devices, but there may be other more subtle measures which might influence the choice of device in clinical practice. Finally, in the course of this study we developed a grading scale to describe the laryngeal views obtained when using a fibrescope passed through supraglottic airway devices.

SLIPA™ may be more useful than other LMADs for difficult airway management

, has advantages over other laryngeal mask airway devices (LMADs) because it provides better protection from regurgitation and has a better perilaryngeal seal. 1 However, SLIPA TM has not been tested in difficult airways. We report successful management of a difficult airway with SLIPA TM after laryngeal mask airway failure. We obtained the patient's written consent to publish this report.A 50-yr-old man (169 cm, 90 kg) with gastroesophageal reflux disease (GERD) was scheduled for reconstruction of finger tendons under general anesthesia. Difficult intubation was anticipated because of the patient's large tongue, short neck, thyromental distance, and a Mallampati score of 4. Because he refused awake fibreoptic intubation, we decided to insert a LMAD. After administering fentanyl 100 lg, thiopental sodium 450 mg, and succinylcholine 90 mg, a LMAD (Solus TM ; Intersurgical Ltd. Wokingham, UK) size 5 was inserted. Immediately after insertion, no leak was heard, the end-tidal carbon dioxide concentration (ETCO 2 ) was 28-30 mmHg, and the peak inspiratory airway pressure (PIP) was 22-25 cm H 2 O. At one minute after insertion, however, the PIP suddenly increased to 35 cmH 2 O, and a leak was detected. The LMAD was removed, and another insertion attempt was made after administering succinylcholine 50 mg. This time, the PIP was 40-45 cm H 2 O, and leaks were audible immediately. A fibreoptic bronchoscope (FOB) was inserted through the airway port of the LMAD, and the anterior portion of the epiglottis was found to be blocking the view. The fibrescope was passed under the epiglottis to examine the glottis, and a glottic narrowing was found.After removing the LMAD, a size 55 SLIPA TM was inserted. The PIP decreased to 20-23 cm H 2 O, and the ETCO 2 was 32-33 mmHg. No leak was detected. The FOB was inserted, through which the vocal cords were well visualized, and the periglottic seal was seen to be improved. Afterward, ventilation was maintained well, and there were no complications, including airway obstruction or aspiration.Examination of the glottis via the FOB provided possible explanations for the different performances of the two devices. First, the position of the epiglottis was different, which might be due to the designs of the respective bowls. The laryngeal aperture of SLIPA TM consists of a wide portion and a narrow portion, preventing airway obstruction (Figure), whereas the absence of epiglottic bars on the Solus TM could cause epiglottis downfolding and subsequent airway obstruction. However, previous reports suggested that because disposable LMADs, including the Solus TM , have a deeper bowl, ventilation is well maintained despite the absence of epiglottic bars. 2,3 In this case, the FOB passed under the epiglottis with ease, which makes obstruction by the epiglottis improbable.Second, the presence of a cuff and the shape and location of the bowl should be considered. The space between the tongue and posterior pharyngeal wall was probably narrow in this patient, becoming narrower because of laryngopharynge...
