Accuro: Clinically Proven Neuraxial Guidance

%

HIGHER first-insertion success rates

%

FEWER paresthesia instances (even for experienced providers)

%

REDUCTION in patients who reported patient satisfaction of less than 4 on a 5-point scale.

Ultrasound Simplified: Pinpoint key neuraxial targets, including the interlaminar space and depth, using Accuro’s AI-enabled image guidance and unique bone-imaging technology. Clinically proven to improve first-attempt success rates, especially in patients with complex anatomy, Accuro’s effectiveness surpasses traditional ‘blind’ palpation methods, regardless of provider experience, the type of neuraxial anesthesia, or previous Accuro training.

Enhance Patient Safety and Clinical Efficiency

More than 3.5 million neuraxial anesthesia procedures are performed annually in the U.S., primarily in the labor and delivery department. With needle placement failure rates ranging from 20% to 80% — largely based on clinician skill, patient BMI, and age — complications such as repeated attempts, long-term pain, and even paralysis in rare yet devastating cases are significant concerns.

Real-World Accuro Success Stories

“Accuro is a game changer… I use it now in all my procedures and to train our residents. Not only are we improving our first-attempt success rates with Accuro, but we are also noticing a reduction in back pain and wet taps. By improving efficiency and reducing risk, we are greatly improving the standard of care we provide to our patients.”

Antonio Gonzalez, M.D.

Assistant Professor of Anesthesiology, Yale School of Medicine

“A morbidly obese patient had two difficult epidural placements by other anesthesia providers. Both epidurals failed after six hours… I utilized the Accuro device and placed a working CSE within five minutes…Both the surgeon and patient were pleased. It was a fabulous example of the need for the device.”

Accuro Use Cases: From Challenge to Triumph.

Patients with above-normal BMI face a higher risk of epidural failure due to less apparent spinal bony structures. Additionally, those with atypical spinal conditions, such as scoliosis or prior surgeries, also face significant risk. Learn how Accuro delivers results for patients with challenging anatomy.

Morbid Obesity: 160 kg and BMI of 60

Dr. Launius highlighted that Accuro provided crucial data; he swiftly achieved loss of resistance and successfully placed the epidural catheter on the first attempt.

Spinal Hardware & Significant Compression

Stephen Garber, MD, an Anesthesiologist at Saddleback Medical Center, used Accuro to facilitate midline and intervertebral space detection for a successful epidural placement during L&D.

Scoliosis with Significant Intravertebral Rotation

Brandon Togioka, MD, Associate Professor at Oregon Health & Science University and Vice Chair of Clinical Research for Anesthesiology @ OHSU, explains.
