KTP laser-resistant properties of the reinforced laryngeal mask airway.
We have assessed, in vitro, the effect of KTP laser strike on the reinforced laryngeal mask airway (RLMA) under a variety of conditions. At power densities normally encountered in clinical practice, using a divergent KTP laser beam, the RLMA could not be penetrated and did not ignite with laser strike. The RLMA was penetrated at a high power density of 6.94 W mm-2 after 45-60 s. A flame appeared over the RLMA shaft at this power density after 12-35 s. The black marker line on the RLMA shaft w...Expand abstract
