“…Some authors have reported failure rates comparable with our own, both in adults and in children [5,17–19]. One group, examining the success rates of anaesthetists with little or no previous experience of the LMA, had a 24% first‐insertion failure rate [20].…”

Removal of the laryngeal mask airway:factors affecting the incidence of post-operative adverse respiratory events in 300 patients

1999

The purpose of this study is to compare the incidence of undesirable respiratory events when the laryngeal mask airway is either removed from patients who are fully awake or from patients who are deeply anaesthetized. Three-hundred patients aged 1.5-81 years were randomly assigned to have their laryngeal mask airway removed either when deeply anaesthetized or after airway reflexes had returned. The occurrence of adverse respiratory events (coughing, oxygen desaturation and airway obstruction) was recorded. Airway obstruction after laryngeal mask airway removal was evident in 20% of patients in the deep anaesthesia group and in 8% of patients in the awake group (P = 0.007). In spite of this finding, oxygen desaturation in children of less than 6 years of age (SaO2 < 96%) occurred most frequently after awake removal (31.3%) compared with deep anaesthesia removal (4.5%) (P = 0.023).

“…Therefore, we focused particularly on the performance and efficacy of SLIPA by novice personnel in the present study. McCrirrick et al [9] defined the 'novice' airway provider as someone who has previously used LMA less than 15 times. However, in the present study, 'novice' personnel are who has previously used any kind of LMA or SLIPA less than 5 times, because there was a short learning curve of about 13 cases for insertion of SLIPA in a previous study [10].…”

BackgroundThe aim of this study was to compare the streamlined liner of the pharynx airway (SLIPA) with the classic laryngeal mask airway when used by novice personnel.MethodsThere were 114 patients enrolled into this study who underwent general anesthesia were randomly allocated into one of 2 groups; LMA group (n = 57) or SLIPA group (n = 57). After insertion, insertion success rate, insertion time, and hemodynamic responses to insertion were accessed. After surgery, postoperative airway morbidity (sore throat, dysphonia, dysphagia) were evaluated.ResultsThe SLIPA was successfully inserted in 96% of patients (55/57) and the LMA in 93% (53/57) (P = 0.408). First attempt success rates were 88% (44/57) and 77% (50/57) in the SLIPA and the LMA (P = 0.142). The successful insertion time in SLIPA group (33.4 ± 11.0 sec) was significantly shorter than that of LMA group (38.8 ± 16.6 sec) (P = 0.048) and the insertion time at the first attempt was also shorter in SLIPA group (31.0 ± 6.3 sec) than LMA group (34.7 ± 8.6 sec) (P = 0.013). There was no statistically significant difference between the two groups in hemodynamic responses and postoperative airway morbidity.ConclusionsThe SLIPA was similar to the LMA in insertion success rate, hemodynamic response, and postoperative airway morbidity by novice personnel. The insertion time at the first attempt and successful insertion time of the SLIPA were significantly shorter than those of the LMA. Therefore, the SLIPA could be a useful alternative to the LMA as primary SGA for novice personnel.

“…Because the larynx is not directly stimulated by laryngoscope or tube, respiratory and cardiovascular responses to insertion of an LMA are decreased in comparison to an ETT5–7; in addition, there is a decreased risk of damage to the teeth from the laryngoscope. The incidence of coughing, gagging, and patient movement at the time of airway device removal is also reduced 8–10. There is also evidence that postoperative respiratory mechanics are improved for those patients who have an LMA versus ETT who are moderately obese (body mass index 30 kg/m 2 ) 11.…”

The laryngeal mask airway and otorhinolaryngology head and neck surgery

et al. 2011

View full text Add to dashboard Cite

The relationship between surgeon and anesthetist is particularly strong in otorhinolaryngology. The impact of airway management on the surgical field and perioperative conditions requires the surgeon to be aware of contemporary tools and techniques available. The LMA has been shown to be safe and efficacious by both the literature and clinical practice. Its use in selected patients should be encouraged.
