This article is based on a literature review comparing insertion techniques of the laryngeal mask airway (LMA). I will be looking at the manufacturer's recommended technique and identifying alternative methods, adapted for ease of use, patient comfort or individual circumstances. Risks associated with LMA use will be identified and examples given of research carried out to limit these risks.

Damage of laryngeal mask airway and other supraglottic airway devices has always been a matter of concern. Although manufacturer recommends maximum 40 uses of LMA (and its congeners) but damage before 40 uses needs to be evaluated. We hereby, describe a novel method of repair of supraglottic devices when damage occurs at mask inflation line or pilot balloon valve assembly.

We studied the size 4 laryngeal mask airway (LMA) to test the hypothesis that oropharyngeal leak pressure and fibreoptic position improves with increasing cuff volume. After LMA insertion, 50 anaesthetized adult patients had the cuff inflated in 5-ml increments to 40 ml. Oropharyngeal leak pressure was optimal at 15 ml and decreased at higher volumes. The fibreoptic position was optimal at 0-20...

The general-purpose laryngeal mask airway (LMA) is re-usable when undamaged, and cleaned and autoclaved correctly. We had found weakening of the silicone adhesive that bonds the connector of the LMA to the tube. We report that repeated autoclaving damaged the adhesive such that the connector could be rotated in the tube after the 12th autoclave cycle in almost all of the LMA tested. The damage ...

I would like to report a feasibility study into the use, in small animal anaesthesia, of a supraglottic airway device, designed for veterinary use. Rabbit anaesthesia carries a higher anaesthetic risk compared with anaesthesia in dogs and cats (Brodbelt et al. 2008). One reason may be that endotracheal intubation can be difficult to perform in rabbits, because they have a narrow pharyngeal inle...

BACKGROUND The purpose of this study was to evaluate the cuff pressures of four different laryngeal masks in paediatric patients undergoing routine surgery and to determine whether there is a substantial increase in cuff pressure when silicone masks are used compared to PVC laryngeal mask airways. METHODS Hundred and forty patients aged < 16 yr were randomly allocated to receive one of four e...

bioaerosols are the most significant risk for exposed people leads to infectious diseases. this study was aimed at evaluation of physical and microscopic characteristics and submicron particulate filtration efficiency of surgical masks used in hospitals throughout iran. five types of domestic (zist filter, elhamteb and arman masks) and imported (blosom, face masks) surgical masks were tested se...
