Three incidents have been reported to webAIRS concerning patients biting through the stem of a flexible Laryngeal Mask (LM) at the time of emergence from anaesthesia while returning to consciousness.
WebAIRS recently received a report of lingual nerve (LN) palsy associated with a dual lumen supraglottic airway device (DL-SGA). The patient woke with a bilateral lingual nerve neuropraxia, described as numbness in the front half of tongue. There was no motor involvement, with normal speech, tongue movement, and eating. They had not noticed less taste until they were asked. It was unchanged three days later. A search of the webAIRS database using structured query
language revealed that a further 15 cases have been reported making 16 in total. In the webAIRS case series, five were associated with the use of a standard single-lumen SGA and 11 with a DL-SGA.
In January 2022, a search of the webAIRS bi-national anaesthetic incident database was conducted. This included the search terms “COVID”, “CV-19”, “Masks”, “N95”, “PPE”, “protect”, or “pandemic” over the period from 11/3/20 to 14/1/22, yielding 76 reports.
In this edition of Australian Anaesthetist, a Bowtie Analysis has been performed on the incident reports involving Medical Devices and Equipment among the first 8000 incidents reported to webAIRS. This main category of incidents accounted for 959 (12%) of the first 8000 reports in an initial interim analysis.
