BACKGROUND: Maintaining the patency of arterial catheters-routinely inserted in critically ill patients in intensive care units (ICUs)-is essential for obtaining physiological measurements and enabling blood sampling.
AIM: This study aims to evaluate current ICU nurse knowledge and practice of maintaining the patency of arterial catheters and explore the factors that influence nurses' knowledge level.
DESIGN: This was a cross-sectional survey conducted in China.
METHODS: This research was conducted in 20 tertiary hospitals in Beijing, China between March and June 2020. The data were collected by electronic questionnaire, which was designed in accordance with the literature and consisted of 28 questions. Descriptive and inferential statistics were used to analyse the data.
RESULTS: A total of 576 completed questionnaires were returned. The mean score of nurses' knowledges was 3.66 ± 1.35, which is a moderate level. There was a statistically significant difference between the mean scores of nurses with different professional titles and work experiences (mean 3.58 vs 4.04/7; mean 3.50 vs 3.58 vs 3.94/7). Considering ICU nurses' practice of maintaining the patency of arterial catheters, 376(65.3%)nurses replaced the pressure transducer as per the manual, and 347 (60.2%) nurses zeroed the pressure transducer once per shift. More than 90% ICU nurses aligned the transducer with the heart surface marker during zeroing procedures. Furthermore, 79.9% of nurses performed fast-flush tests routinely, 459 (85.9%) nurses flushed the arterial catheter routinely, and 80% of nurses evaluated the patency of the arterial catheter every shift.
CONCLUSIONS: This study found that the practices of ICU nurses varied, and their knowledge of how to maintain the patency of arterial catheters was moderate and could be improved. ICU nurses should be trained effectively to develop a unified standard of arterial catheter management.
RELEVANCE TO CLINICAL PRACTICE: Training programmes on arterial catheter management for ICU nurses are essential for improving knowledge and practice.
