Most patients need intravenous access in the emergency department, but many suffer multiple attempts before the health provider is successful. This can cause patient distress and delays the time to potentially life-saving treatments. We believe an ultrasound-guided cannulation training program will enable better recognition of patients with difficult intravenous access and increase use of ultrasound during cannulation, hence decreasing time to cannulation, increasing success rates, and reducing the number of punctures required. In this study, we are examining the current practice of inserting intravenous (IV) cannulas in the Emergency Department at the Gold Coast University Hospital. We will consider how many people get cannulas, number of attempts required, who inserts them, how successful we are, how often ultrasound is used to guide this insertion, time to successful cannulation, who uses ultrasound and how successful is ultrasound-guided placement.
The clinicians ran a year long intervention program for emergency department doctors and nurses to improve knowledge and skills in identifying patients with difficult IV access and to learn ultrasound-guided cannulation. Almost 100 clinicians took part in ultrasound training and more than 1000 patients were involved in the research.
The research team found that the training program improved clinician confidence in using ultrasound to guide cannulation. However, clinicians were only turning to ultrasound after three or more attempts to place a cannula in a patient. Consequently, the research team recommended using ultrasound to guide cannulation earlier for difficult patients.
Ultrasound training is continuing for clinicians at the Gold Coast University Hospital Emergency Department and educational materials are being made available for patients.
