1. Frequency distribution of clinical trials involving first-generation and second-generation supraglottic airway devices (SADs).
Frequency distribution of clinical trials involving first-generation and second-generation supraglottic airway devices (SADs). A literature search of clinical trial publications on PubMed using the search terms “laryngeal mask,” “supraglottic airway,” and “supraglottic airway device,” and the names of each of the first-generation and second-generation devices showed that the majority of studies were conducted on first-generation SADs. The majority of clinical trials continue to be based on the LMA Classic, which has traditionally been considered the accepted standard.
