Tracheostomy tube cuff care is associated with a high risk of the patient’s health, it is important that nurses should have scientific evidence-based knowledge about the cuff care. If the nurses will have the knowledge and good practical skills to supervise quality tracheostomy tube cuff, it will reduce the frequency of adverse events and ensure patient safety. The aim is to analyze nurses’ knowledge of the tracheostomy tube cuff care before and after the training. The study was carried out in 2013 in Kaunas hospital departments in which patients with tracheostomy usually comes from the intensive care unit. The study included 111 nurses. The study was carried out in stages: 1. Nurses questionnaire before training; 2. Nurses’ training; 3. Nurses survey after the training. The survey before the training attended by 93 nurses after training – 81. The studies, data collection and evaluation were used in the authors developed “Nurses knowledge’s determination”. Results. Most of the nurses said that a special cuff pressure monometer does not measure (before training – 95.2 percent, followed by training – 98.3 percent). Before and after training, almost half of nurses said that never blow air into the tracheostomy cuff (before training – 47.6 percent, followed by training – 45.8 percent). After training significantly more nurses (44.4 percent) indicated that the air from the tracheostomy cuff spends every three – four hours. Before training as did 20.1 percent of respondents (χ² = 12.162, df = 1, p = 0.007). Before training for 60.9 percent of nurses indicated that the whole do not discharge air from the tracheostomy cuff, after training as claimed 40.3 percent of nurses (χ² = 12.162, df = 1, p = 0.007). After teaching at 50.6 percent of nurses indicated that the cuff pressure should be less than 20 cmH2O before training the pressure indicated 3.6 percent of respondents (χ² = 59.048, df = 3, p < 0.001). After teaching at 21.0 percent of nurses said that the tracheostomy cuff pressure is not important, it is important that it would be much exaggerated , before training as claimed 65.5 percent of the surveyed nurses (χ² = 59.048, df = 3, p < 0.001). The majority (79.6 percent) of nurses, after the training said that the release of air from the tracheostomy cuff suck secretions from the mouth and nasopharynx, before training as did 51.7 percent of respondents (χ² = 9.007, df = 1, p = 0.003). Conclusions. After training the greater part of the nurses correctly pointed that the air from the tracheostomy cuff is released every three – four hours, and the cuff pressure must not be less than 20 cmH2O. A significantly higher proportion of nurses after the training said that the release of air from the tracheostomy tube cuff suck secretions from the mouth and nasopharynx. Before and after training the majority of respondents said that a special cuff pressure manometer does not measure, and the air in the cuff by the pressure gauge readings inflate only a small part of the nurses.
