OBJECTIVE: To determine if the skills to successfully ventilate using the laryngeal mask (The Laryngeal Mask Company Limited, Henley on Thames, United Kingdom) and Combitube (The Kendall Company, Mansfield, USA) can be retained after seven months. METHODS: Nursing, medical and theatre staff from Dunedin Hospital were recruited in a prospective study. Subjects were taught to insert and ventilate an Ambuman manikin using both devices. Subjects were tested on their ability to ventilate the manikin with both devices within one month then following a six-month period. RESULTS: A total of 101 subjects were recruited with 86 subjects retested at least six months later. Initial testing resulted in subjects successfully ventilating the manikin in 90% (laryngeal mask) and 92% (Combitube) of attempts. At retesting, successful ventilation was achieved in 85% (laryngeal mask) and 77% (Combitube) of attempts. The decline in skills level was significant for the Combitube only (95% CI 4% to 26%). CONCLUSION: The ability to successfully ventilate is better maintained with the laryngeal mask than the Combitube after seven months.
