“…We selected two consecutive expired tidal volumes of 8 ml/kg as the criteria for an effective airway, as two consecutive breaths demonstrate better airway control than one breath, and 8 ml/kg is the average tidal volume of a resting adult. Similar criteria have been used previously (19). We inflated the cuff to the maximum recommended volume, as it is a simpler instruction than that recommended for anesthesia, which is to inflate the cuff to the minimal volume required to form an effective seal.…”

“…First time insertion rates using the standard technique as described by Brain [7] vary from 74% [8] to 95% [4] depending on experience, but it is notable that as many as 16 alternative methods of laryngeal mask insertion have been described [I] suggesting that, at least some anaesthetists, at some time, experience difficulty. One of the reasons for its popularity is that it gives the anaesthetist more freedom to attend to other tasks, (e.g.…”

A comparative study of the incidence of sore throat with the laryngeal mask airway

1994

In a prospective study of I50 patients randomly assigned to three groups, we have compared the incidence and duration of sore throat after a standard anaesthetic regimen using three different methods of airway management: facemask; laryngeal mask, and laryngeal mask with insertion aid. The insertion aid is currently being developed by Portex Ltd and is intended both to facilitate accurate placement of the laryngeal mask and to reduce trauma during insertion. All the patients were women undergoing short operative procedures requiring minimal postoperative analgesia. The incidence of sore throat was significantly less with a facemask (8%) than with the laryngeal mask when used without the insertion aid (28.5%) ( p < 0.02). When using the insertion aid the incidence was 18% and this was not statistically different from the facemask. The presence of blood on the laryngeal mask (22%) was less likely when the insertion aid was used (4%) ( p < 0.02).

“…However, first attempt LMA placement success rates lower than 80% have been reported in the literature [24-26], suggesting that additional training, particularly for students with little clinical exposure, is required. This observation leads to a hypothesis for further testing: the need for simulation training increases with the degree of difficulty of the task.…”

The effects of laryngeal mask airway passage simulation training on the acquisition of undergraduate clinical skills: a randomised controlled trial

BackgroundEffective use of the laryngeal mask airway (LMA) requires learning proper insertion technique in normal patients undergoing routine surgical procedures. However, there is a move towards simulation training for learning practical clinical skills, such as LMA placement. The evidence linking different amounts of mannequin simulation training to the undergraduate clinical skill of LMA placement in real patients is limited. The purpose of this study was to compare the effectiveness in vivo of two LMA placement simulation courses of different durations.MethodsMedical students (n = 126) enrolled in a randomised controlled trial. Seventy-eight of these students completed the trial. The control group (n = 38) received brief mannequin training while the intervention group (n = 40) received additional more intensive mannequin training as part of which they repeated LMA insertion until they were proficient. The anaesthetists supervising LMA placements in real patients rated the participants' performance on assessment forms. Participants completed a self-assessment questionnaire.ResultsAdditional mannequin training was not associated with improved performance (37% of intervention participants received an overall placement rating of > 3/5 on their first patient compared to 48% of the control group, X2 = 0.81, p = 0.37). The agreement between the participants and their instructors in terms of LMA placement success rates was poor to fair. Participants reported that mannequins were poor at mimicking reality.ConclusionsThe results suggest that the value of extended mannequin simulation training in the case of LMA placement is limited. Educators considering simulation for the training of practical skills should reflect on the extent to which the in vitro simulation mimics the skill required and the degree of difficulty of the procedure.
