“…Our data on neutral OLP values and, commensurately, our V T max values for the air-Q ILA are lower than existing published data for the PLMA. [2][3][4]14 Our findings for air-Q ILA sizes 1.5 and 2.0 are similar to those previously published, 10,11 where the mean (standard deviation [SD]) OLP was 17.5 (6.4) cm H 2 O and 18.5 (1.6) cm H 2 O for size 1.5 and 15.7 (4.3) cm H 2 O for size 2.0. Our OLP findings for size 1 were higher than those by Sinha et al 11 who reported a mean (SD) OLP of 18.5 (2.1) cm H 2 O. Oropharyngeal leak pressures increase when the patient's neck is in the flexed position, a phenomenon also described with the PLMA.…”

“…Previously published studies of performance of new iterations of LMAs in adults and children have used similar group sizes. [2][3][4] Data are described with median [P25,P75] for continuous data and frequency (percent) for discrete and categorical data. Due to its observational design, this study was not powered for comparisons, and as such, no inferential methods of statistical analysis were employed.…”

“…Pediatric-sized PLMAs are also available and provide superior performance with respect to sealing pressures when compared with the LMA Classic. [2][3][4] The LMA Fastrach is a much bulkier device and is not available in pediatric sizes. Consequently, the SGD options for airway rescue in the difficult pediatric airway are limited.…”

Purpose The air-QÒ intubating laryngeal airway (ILA) is a supraglottic device (SGD) designed specifically to function as both a primary airway and a bridging device and conduit for fibreoptic intubation in difficult airway scenarios. This observational study evaluated the usability and performance characteristics of pediatric air-Q ILA sizes 1.0, 1.5, 2.0, and 2.5 when used as a primary airway. Methods One hundred ten children, American Society of Anesthesiologists physical status I-III and undergoing elective surgery, received a weight-appropriate air-Q ILA following induction of anesthesia. The evaluation criteria included ease of insertion, quality of ventilation, presence of gastric insufflation, oropharyngeal leak pressures

“…In a bench study fluid was injected into a model esophagus: at 15 mL·sec -1 the PLMA prevented aspiration; at 30 mL·sec -1 , or with the DT occluded, protection was reduced but better than the cLMA. 51 In ten fresh cadavers with a PLMA in place and the DT open, incremental filling of the esophagus did not cause tracheal soiling. 53 The PLMA provided better airway protection during 'regurgitation' than the cLMA.…”

“…The PLMA was associated with a higher seal pressure and maximum tidal volume, less gastric inflation and improved laryngeal view compared to the cLMA. 51 In another study of 60 children: insertion, airway seal and fibreoptic view were all equivalent. 52 OGT passage was successful in all patients in both studies.…”

CAN J ANESTH 55: 1 www.cja-jca.org Januar y, 2008Purpose: To determine whether a functional difference exists between the size 2 laryngeal mask airway (LMA)-Classic™ (CLMA) and LMA-Proseal™ (PLMA) in anesthetized children who have received neuromuscular blockade. Airway leak during intermittent positive pressure ventilation (IPPV) and adequacy of fibreoptic laryngeal view were the primary study outcomes. Methods:A randomized, controlled, single-blinded study of 51 ASA I or II children weighing 10-20 kg was undertaken. The anesthetic technique was standardized. Following insertion of the LMA and cuff inflation to 60 cm H 2 O, we measured oropharyngeal leak pressure and gastric insufflation and leak fraction during IPPV, and evaluated the adequacy of fibreoptic view.Results: Oropharyngeal leak pressure measured by neck auscultation was higher for the PLMA compared to the CLMA (23.7 vs 16.5 cm H 2 O, P = 0.009) but, when measured by the inspiratory hold maneuver was not significantly different (24.8 vs 20.3 cm H 2 O, respectively, P = 0.217). Leak fraction values were similar for the CLMA and the PLMA (21.2%. vs 13.3%, respectively, P = 0.473). A satisfactory view of the larynx was obtained more frequently in the PLMA group (21/25 vs 10/25, P = 0.003). Gastric insufflation during leak determination was more common with the CLMA (12/26 vs 2/25 CLMA vs PLMA, respectively, P = 0.006). Conclusion:In children undergoing IPPV with neuromuscular blockade, the size 2 PLMA is associated with a higher leak pressure by auscultation and less gastric insufflation compared to the CLMA. Leak pressures assessed by manometric stability are similar with these two devices. The improved fibreoptic view of the larynx through the PLMA may be advantageous for bronchoscopy. CLMA (23,7 vs 16,5 cm H 2 O, P = 0,009) ; toutefois, lorsque celle-ci a été mesurée par manoeuvre de retenue respiratoire, il n'y a pas eu de différence significative (24,8 vs 20,3 cm H 2 O, respectivement, P = 0,217). Les valeurs de fraction de fuite étaient semblables avec le CLMA et le PLMA (21,2 % vs 13,3 %, respectivement, P = 0,473). Une vision satisfaisante du larynx a été plus fréquemment obtenue dans le groupe PLMA (21/25 vs 10/25, P = 0,003). L'insufflation gastrique pendant la détermination de la fuite a été plus fréquemment observée dans le groupe CLMA (12/26 vs 2/25 CLMA vs PLMA, respectivement, P = 0,006).
