AI Article Synopsis
- The rise of ultrasound technology enables anesthesiologists to conduct nerve blocks more effectively, reducing the need for nerve stimulation or causing tingling sensations.
- A significant challenge remains in accurately visualizing the positions of peripheral nerve catheters with ultrasound.
- The new method introduced involves using agitated contrast injection to confirm the placement of an interscalene catheter tip, making it a straightforward and efficient assessment technique.
Article Abstract
The increasing use of ultrasound has allowed anesthesiologists to perform nerve blocks with a high success rate and without nerve stimulation or eliciting a paresthesia. The ability to visualize peripheral nerve catheters using ultrasound is limited. We present a novel method to confirm the position of an interscalene catheter tip using injection of agitated contrast. The described technique is simple and allows timely assessment of catheter tip position.
