Interventional Pain Management Physicians, PM&R, Radiologists, and Anesthesiologists often prefer an Epidural Procedural Tray that contains a Hustead Epidural Procedural needle to administer effective Interventional Pain Management injections. Several Hustead Epidural Procedural Trays contain a plastic Pulsator® LOR syringe (some do not) and either an 18G x 3.5" or 20G x 3.5" Hustead Epidural Procedural needle, depending upon the physician's preference. The Hustead Epidural Procedural Tray line includes seven different tray component variations.
