What is the difference between the EPD and E-EPD? featured image

PHS Medical's patented Epidural Positioning Device and Electric Epidural Positioning Device feature unique torso positioning for proper cervical alignment to position patients safely and comfortably during epidural procedures.

To better understand the EPD and E-EPD, we've outlined the main similarities and differences between them.

Correct Positioning

Both the EPD and E-EPD are designed to encourage cervical, thoracic and lumbar flexion while maintaining a solid and stable position. This reduces safety and positing concerns and helps the anesthesiologists perform a successful block.

Supports Various Patient Sizes

The height range of both devices is 50" - 60" to accommodate for different sized tables/beds and patients.

Patients of various sizes can be supported by the EPD and E-EPD. It can be used with patients up to 600 lbs.

Where It's Used

They are both predominantly used in labor & delivery suites and surgical departments, but they’re also beneficial in pain management clinics. Anywhere epidural or spinal anesthesia is administered while the patient is seated, the EPD or E-EPD can be of use.  Some hospitals have been using them for thoracentesis as well.

Easy to Move & Lock

Both the EPD and E-EPD have a locking caster system that makes it easy to move and easy to lock.




The main difference between the EPD and E-EPD is how you adjust them. An electronic hand control adjusts the E-EPD to the correct height and foot position for each patient and easy mechanical lock and release systems adjust the chest, arm and head pieces. On the EPD, manual controls adjust the height, foot, chest, arm and head supports.
