“…Both supraglottic airway devices had approximately equal incidences of intra-operative airway obstruction, mainly associated with the insertion of the mouth gag, which were similar to those previously quoted for the reinforced LMA in dental surgery [1,4]. Intra-operative re-adjustment of the devices was required in < 5% of cases in both groups.…”

“…Laryngeal mask airways have been shown to provide more reliable airway control with a superior cardiovascular profile when compared to nasal masks in dental anaesthesia [1], and in addition provide protection from contamination of the tracheobronchial tree with blood from the oral and nasal cavities [2,3]. The reinforced laryngeal mask airway can safely replace nasotracheal intubation and provide satisfactory conditions for dento-alveolar surgery [4], and has been shown to be more cost effective because of a shorter procedure and recovery time [5]. In comparison with the LMA Classic TM (cLMA TM , Intavent Orthofix, Maidenhead, UK), the LMA Flexible TM (Intavent Orthofix) provides improved surgical access, as a consequence of the increased flexibility, longer length and reduced external diameter of the device, and reduces the incidence of intra-operative airway obstruction [1].…”

A randomised comparison of the single use LMA Flexible^™ with the reusable LMA Flexible^™ in paediatric dental day‐case patients

SummaryIn this study we compared the performance of the single use flexible laryngeal mask airway (LMA Flexible™) with the original reusable LMA Flexible™ in paediatric dento‐alveolar day‐case surgery. The aim of the study was to determine whether these two supraglottic airway devices were clinically equivalent when used for simple dental extractions in children under general anaesthesia. This randomised comparative trial in 100 healthy children used first attempt airway insertion success as its primary outcome measure. Secondary outcomes included the adequacy of ventilation, incidence of airway obstruction and the requirement for device manipulation and the incidence of adverse airway outcomes during recovery from anaesthesia. No difference was found between the devices in first attempt insertion success rate (94% with reusable LMA Flexible and 90% with single use LMA Flexible, p = 0.358), and ease of insertion was also similar (p = 0.5). Both devices performed equally well during surgery, with no significant differences in episodes of intra‐operative airway compromise (p = 0.387), and both the single use and reusable LMA Flexible displayed excellent recovery characteristics, with no occurrences of emergence airway obstruction. No blood was discovered within the inner LMA tube shaft in either device, implying that both protected against tracheobronchial soiling. We conclude therefore that the single use LMA Flexible is an acceptable alternative to the reusable LMA Flexible.

“…The head and neck may be turned with a decreased risk of airway dislodgement during surgery. Studies have detailed its usefulness compared with tracheal intubation in dental day surgery patients [4,5], but few studies have examined different techniques of insertion. Therefore, we evaluated the use of a laryngoscopy-guided technique as an alternative to the standard technique of digital manipulation for insertion of the LMA Flexible, in adult patients presenting for day-case dental surgery.…”

SummaryThe Laryngeal Mask Airway Flexible TM (LMA Flexible) has been widely utilised for dental, ophthalmology and otorhinolaryngology-related procedures. Our study evaluates two different techniques of inserting the LMA Flexible for patients undergoing day-case dental surgery. One hundred and eight patients were randomly assigned into two groups based on the LMA Flexible insertion technique -either laryngoscopy-guided (n = 54) or digital manipulation (standard technique; n = 54). Patient and airway characteristics were recorded before induction of anaesthesia. The primary outcome was success rate at first insertion. Other outcomes assessed included fibreoptic assessment of laryngeal mask airway placement, haemodynamic changes, need for airway adjustment during surgery and sore throat. The success rate of insertion on the first attempt was higher for the laryngoscopy-assisted technique compared with the standard technique (96.3% vs 81.5%, respectively, p < 0.05). Fibreoptic assessment showed that the former group had better placement of the laryngeal mask airway than the latter (59.3% vs 37% p < 0.05). There were no significant differences between the two groups for haemodynamic changes. Sore throat was more common in the group with the standard technique (35.2% vs 16.7%, p < 0.05). Our study suggests the use of the laryngoscope to guide insertion of the LMA Flexible for dental surgery is a better option compared with the standard technique of digital manipulation. Laryngeal Mask Co. Limited, Mahe, Seychelles) has been widely used for dental, head and neck-related surgery [1][2][3]. The cuff portion is identical to the classic version of the LMA, but the LMA Flexible has a long and nonrigid flexometallic tube, which may make insertion more challenging. This unique design allows greater movement of the tube without displacement of the cuff or loss of seal. The head and neck may be turned with a decreased risk of airway dislodgement during surgery. Studies have detailed its usefulness compared with tracheal intubation in dental day surgery patients [4,5], but few studies have examined different techniques of insertion. Therefore, we evaluated the use of a laryngoscopy-guided technique as an alternative to the standard technique of digital manipulation for insertion of the LMA Flexible, in adult patients presenting for day-case dental surgery.

“…Recent studies show that the LMA Flexible provides a satisfactory airway in oral surgery and dental treatments and protects against soiling of the upper and lower airway 22, 23. It is certainly preferable to the now largely defunct technique of nasal mask anaesthesia, which was routinely carried out in the dental extraction of deciduous teeth.…”

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.
