Clinical Value

Improve the safety, speed, and efficiency of epidural and spinal anesthesia.

Because Accuro automatically identifies epidural location with success rates exceeding 94%*, Accuro gives you confidence when performing epidurals or spinals, even in the most challenging patients.

Clinically Proven Benefits
