Philips, together with German anesthesia and pain management experts, B. Braun, have announced the launch of Onvision – an ultrasound guidance solution for real-time needle tip tracking for the use of regional anesthesia. Designed to enhance the precision of needle positioning, the new technique is available on the latest version of the duo’s ultrasound system, Xperius.

The accurate placement of needles is crucial for the success of regional anesthesia procedures, such as peripheral nerve blocks, both in terms of effective pain relief and the avoidance of unintended nerve and vessel punctures or collateral damage to surrounding tissue. While real-time ultrasound imaging has proved to be a valuable tool for needle guidance, failure to optimally visualize the needle tip remains a challenge for both novice and experienced anesthetists. Currently, 10-20 percent of all peripheral nerve blocks are ineffective on the first attempt. By simplifying alignment between the needle and ultrasound probe, Onvision reduces the effort needed to interpret the ultrasound image, allowing anesthesiologists to confidently guide the tip of the needle to its target.

“Regional anesthesia is a rapidly growing alternative to general anesthesia and has the potential to improve patient outcomes as well as increase workflow efficiency in the hospital,” said Bert van Meurs, Chief Business Leader, Image Guided Therapy at Philips. “By combining B. Braun’s expertise in needle design with Philips’ capabilities in real-time image guidance, we’ve created a solution to one of the biggest challenges in regional anesthesia – accurate positioning of the needle tip in the body.”
