Randomized Controlled Trial Comparative Study
Ultrasound-guided radial artery catheterisation increases the success rate among anaesthesiology residents: a randomised study.
The palpation technique is generally used for radial artery catheterisation, but is associated with a high rate of failure and complications. Dynamic needle tip positioning (DNTP) is a new ultrasound-guided technique. We aimed to compare the traditional palpation technique with DNTP performed by four anaesthesiology residents. ⋯ Ultrasound-guided arterial catheterisation using the DNTP technique is superior to the standard palpation technique. This study favours the ultrasound-guided DNTP technique as the first choice rather than merely being viewed as a rescue procedure.
