ABSTRACT
Objective To understand the status of implementation of invasive ventilator circuit changes in ICU nurses at the 3A general hospitals in Shanxi Province, and mastering and demand of related knowledge of ICU nurses, and by this discuss the possible causes of execution inconsistency in invasive ventilator circuit changes interval so as to provide a clear basis for the specification and circuit changes. Methods After a review of relevant literature at home and abroad as well as expert consultation, a self-designed questionnaire was established, take two ways of on-site issuance and mailing, ICU nurses from 13 hospitals were selected randomly to investigate about the invasive circuit changes interval in Shanxi Province. Results A total of 724 nurses from 34 ICU of 13 hospitals were surveyed. A unified circuit changes interval of ICU accounted for 73.5% (527/717). ICU nurses currently provisions and practical implementation of invasive ventilator circuit changes interval tend to 7 d. Different ICU provisions and ICU nurses actual implementation of circuit change were significantly different (χ2=24.839, 35.760, P < 0.01). Conclusions Hospitals should choose the right way to strengthen the ICU nurses invasive ventilator circuit changes training interval and knowledge, to develop the term for their own security environment, thereby reduce the workload of nurses, reduce medical costs and improve care service quality.
