Attitudes towards three ultrasound-guided vascular access techniques in a paediatric emergency department. 
although nurses often place peripheral intravenous (IV) catheters, little is known about their perceptions regarding use of ultrasound guidance.  the authors aimed to determine paediatric emergency department nurses' attitudes toward ultrasound-guided IV access techniques and assessed practice change after training.  In a cross-sectional study of nurses, they had didactic and hands-on practice sessions, using three short-axis ultrasound-guided IV access techniques on gel models.  Outcomes included likability and ease of learning and performing the techniques.  A 3-month follow-up questionnaire assessed attitudes and behavioural changes.  18 nurses were enrolled and 17 analysed.  Participants liked all three techniques and thought they were easy to learn and perform.  Eighty-two percent of the nurses used at least one technique clinically.  The two-person self-guided technique was most preferred (65%) and used 3 months later (65%).  nurses reported generally positive attitudes toward all three ultrasound-guided IV access techniques, but preferred the two-person self-guided technique.  Owing to the small sample size, these results cannot be generalised and further research is needed.
