Summary In this randomised crossover manikin study of simulated difficult intubation, 26 anaesthetists attempted to intubate the trachea using two fibreoptic-guided techniques: via a classic laryngeal mask airway using an Aintree intubating catheter and via an intubating laryngeal mask airway using its tracheal tube. Successful intubation was the primary endpoint, which was completed successfully in all 26 cases using the former technique, and in 5 of 26 cases using the latter (p < 0.0001). The former technique also proved quicker to reach the vocal cords with the fibrescope (median (IQR [range])) time 18 (14,20 [8,44]) s vs 110 (70,114 [30,118]) s, respectively; p = 0.008); and to first ventilation (93 (74,109 [52,135]) s vs 135 (79,158 [70,160]) s, respectively; p = 0.0038)]. We conclude that in simulated difficult intubation, fibreoptic intubation appears easier to achieve using a classic laryngeal mask airway and an Aintree intubating catheter than through an intubating laryngeal mask airway.

Comparison of fibrescope guided intubation via the classic laryngeal mask airway and i-gel in a manikin,

Summary We compared the classic laryngeal mask airway and i-gel as adjuncts to fibrescope guided intubation in a manikin. Two methods of intubation were compared with each device: the tracheal tube directly over the fibrescope; and the tracheal tube over an Aintree Intubation Catheter. Thirty-two anaesthetists took part in this randomised crossover study. Each anaesthetist performed two intubations with each method via each device. The mean (SD) time for the first intubation using the tracheal tube over the fibrescope was 43 (24) s with the classic laryngeal mask airway and 22 (9) s with the i-gel (95% CI for the difference 12,30 s, p < 0.0001). The mean (SD) times for the first intubation when using the Aintree Intubation Catheter was 46 (24) s with the classic laryngeal mask airway and 37 (9) s with the i-gel (95% CI for the difference 5,12 s, p < 0.0001). We recorded five (5/64, 8%) oesophageal intubations when using the classic laryngeal mask airway and none when using the i-gel. The participants rated the ease of railroading of the tracheal tube and railroading the Aintree Intubation Catheter over the fibrescope to be significantly easier (p < 0.0001 and p = 0.002 respectively) when using the i-gel than when using the classic laryngeal mask airway. Furthermore, 30/32 (94%) of anaesthetists reported preference for the i-gel over the classic laryngeal mask airway for fibrescope guided tracheal intubation when managing a difficult airway. We conclude that the i-gel is likely to be a more appropriate conduit than the classic laryngeal mask airway for fibrescope guided intubation irrespective of the intubation method used. [source]

Fibreoptic intubation through the laryngeal mask airway: effect of operator experience,

Summary In a randomised crossover study, we compared times and success rates for tracheal placement of a fibrescope and railroading of a tracheal tube through the classic laryngeal mask airway by anaesthetists with limited experience in fibreoptic intubation (trainees) and those who were experts. Thirty-two patients, 32 trainees and three experts took part. The median (IQR [range]) times to fibrescope placement for trainees and experts were 21 (18,30 [12,58]) s and 17 (14,24 [9,55]) s, respectively (95% CI for the difference 2,8 s; p = 0.023). There were no significant differences between trainees and experts in the times to placement of the laryngeal mask airway (41 (33,47 [31,105]) s and 36 (33,43 [30,52]) s, respectively; p = 0.24), railroading times (43 (40,58 [33,87]) s and 44 (38,57 [31,83]) s, respectively; p = 0.96) and total intubation time (114 (97,127 [80,213]) s and 95 (89,116 [74,139]) s, respectively; p = 0.13). There was no significant difference in the number of attempts needed for successful placement of the fibrescope (p = 0.12) and railroading the tracheal tube (p = 0.22). The differences between experts and trainees when using fibrescope assisted intubation via the classic laryngeal mask airway were not clinically important. [source]

A randomised crossover trial comparing the i-gel supraglottic airway and classic laryngeal mask airway,

Summary In a randomised cross-over study, we compared the performance of the single use i-gel supraglottic airway and reusable classic laryngeal mask airway (cLMATM) in 50 healthy anaesthetised patients who were breathing spontaneously. Primary outcome was successful insertion at first attempt. Secondary outcomes included overall insertion success rate, ease of insertion, leak pressure and fibreoptic position. Success rate for insertion at the first attempt was significantly different (54% with i-gel vs 86% with cLMA; p = 0.001). Overall success after two attempts (when the anaesthetist was allowed to change the size of the device) improved to 84% with i-gel vs 92% with cLMA; p = 0.22. In 14 patients, the i-gel when used first needed to be replaced with a larger size. Leak pressure was higher for the i-gel (median [IQR] 20 [14,24] cm H2O than the cLMA 17 [12,22] cm H2O; p = 0.023). The fibreoptic view through the device was significantly better with the i-gel than the cLMA, which was statistically significant (p = 0.03). We conclude that, with its current sizing recommendations, the i-gel is not an acceptable alternative to cLMA. However because of the significantly improved success rate after a larger sized i-gel was used, we recommend the manufacturer to review the sizing guidelines to improve the success rate. [source]

A case series of the use of the ProSeal laryngeal mask airway in emergency lower abdominal surgery

ANAESTHESIA, Issue 9 2008

Summary The ProSeal laryngeal mask airway (PLMA) has been used routinely for anaesthesia and for difficult airway management including airway rescue in non-fasted patients. Compared with the classic laryngeal mask airway the PLMA increases protection against gastric inflation and pulmonary aspiration, by separating the respiratory and gastro-intestinal tracts. The PLMA has potential advantages over use of the tracheal tube including smoother recovery, reduced pharyngolaryngeal morbidity and even reduced postoperative pain. We report a series of patients scheduled for emergency appendicectomy, without other risk factors for regurgitation, managed with the PLMA. Anaesthesia was induced and maintained with remifentanil, target controlled propofol and rocuronium. A series of 102 cases were managed without complications and high rates of first time placement of the PLMA (inserted over a suction tube placed in the oesophagus). With careful patient selection the PLMA may offer an alternative airway for use by experienced anaesthetists in patients undergoing minor lower abdominal surgery. [source]
