Ultrasound-Guided Needle Injections
Forward-thinking anesthesiologists recognize the advantages of using ultrasound guidance to help improve care, increase efficiency, and decrease complications during procedures requiring needle placements.
Because an anesthesiologist can visualize the needle in real time through ultrasound technology, injections have a greater chance of hitting their mark with fewer complications. This contributes to increased precision and efficiency during procedures such as steep angle injections, nerve blocks (upper extremity blocks, neuraxial blocks, femoral nerve blocks, brachial plexus blocks, regional pain blocks), and epidurals.
A growing body of research supports the advantages of ultrasound guidance for regional anesthesia. For example: with ultrasound guidance compared to peripheral nerve stimulation, there was shown to be a significant decrease in the risk of vascular puncture (risk ratio of .16); an increase in the nerve block duration by 25%; and a 29% faster onset time1.
A study published in the June 2013 Academic Emergency Medicine (AEM) Journal reported that ultrasound-guided three-in-one femoral nerve blocks significantly reduced pain intensity over four hours and decreased the amount of rescue analgesia when used as an adjunct to standard treatment with parenteral opioids for older adults in the ED experiencing pain with hip fractures. The same study also found that standard pain management with parenteral opioids alone provided ineffective pain control in the study cohort of patients with severe pain from their hip fractures2.
Engineered specifically for anesthesiologists and busy operating rooms, the SII can be mounted on a wall, ceiling, or stand for dependable accessibility. Its lean, simplified controls are designed for single-hand operation, and its visualization quality aids imaging confidence. Along with SonoSite's outstanding customer service, clinical support, and ongoing education, the SII adds up to total access.
A favorite across a wide spectrum of medical specialties, M-Turbo delivers striking image quality with sharp contrast resolution and clear tissue delineation.
SonoSite's top-of-the-line hand-carried system features advanced visualization algorithms, largest display screen, splash-resistant silicone keyboard, and a solid aluminum core.
One option SonoSite offers that helps to assure the accuracy of ultrasound-guided injections is Advanced Needle Visualization (ANV). This propriety algorithm improves needle reflectance and contributes to needle visibility during steep angle approaches for deep targets. ANV uses a dedicated signal path with highly steered ultrasound beams and patent-pending algorithms that automatically identify and extract the needle information from that of surrounding tissue.
This "point-and-shoot" option combines ultrasound with advanced magnetics to provide real-time information about the needle-tip location during placement of central lines. Engineered for ease of use and control, AxoTrack is a two-part system comprised of a specially designed ultrasound transducer and a single-use sterile procedure kit (Compatible with select SonoSite systems, including S Series and M-Turbo.)
This highly practical module allows the connection of up to three transducers simultaneously. Anesthesiologists can fluidly switch from one transducer to another and go from superficial to deep procedures at the push of a button. (Compatible with select SonoSite systems, including Edge, M-Turbo, and the S Series.)
