EVD Nursing In-Service: What a Rep Should Cover on Day One

An EVD nursing in-service should teach the device, not the clinical protocol. On day one, a rep should show neuro-ICU nurses how the system is assembled, how the scale and drip chamber read, how the bag is emptied or changed, and where each clamp is. The hospital’s own policy governs drain settings and patient care.

That line between device education and clinical practice is the most important thing for a rep to respect. Nurses do not need a distributor to tell them how to manage intracranial pressure. They need someone who knows the product in detail and can answer “what does this part do?” with confidence. This article sets out a practical agenda for a first in-service on a DESU EVD system.

Nurses form a view of a new system in the first few shifts. If the setup is confusing on day one, workarounds appear and complaints follow. If the first sessions are clear, practical and respectful of nurses’ time, the product starts with goodwill. Many evaluations are effectively decided at the bedside long before the value-analysis committee meets again.

What should a rep prepare before the session?

Preparation turns a 20-minute session into a useful one. Before arriving, a rep should:

• Agree the scope with the nurse educator, including which units and shifts to cover.
• Bring enough demonstration units for hands-on practice, not just one on a table.
• Read the Instructions for Use closely and mark the steps nurses ask about most.
• Prepare a one-page quick-reference sheet based strictly on the IFU.
• Know the hospital’s current system so differences can be explained clearly.
• Have a contact route for questions the rep cannot answer on the spot.

A day-one agenda that fits a shift

Neuro-ICU nurses rarely have more than 15 to 30 minutes away from patients. A tight agenda respects that.

How should the system components be explained?

The measuring or pressure scale

Nurses level and zero the system many times a day, so the scale is where clarity matters most. On the EVD-010 Series, show the 30 cm measuring scale and how the drip chamber position is read against it. On the EVD-020 Series, show the pressure scale. Point out how the scale relates to the reference point the hospital uses, but leave the choice of reference and settings to the unit’s policy.

The drip chamber

The drip chamber is where CSF first collects. The EVD-010 Series has a 150 ml drip chamber. Show how it is read, how it is emptied into the bag and what to check after emptying. These are the steps nurses perform hourly and should feel automatic.

The drainage bag and filter

The EVD-010 Series has an 800 ml drainage bag; the EVD-020 Series includes a drainage bag and a filter. Demonstrate the bag change sequence as written in the IFU, emphasizing closed handling. Explain where the filter sits and why it should not be wetted, if the IFU addresses it.

What questions do nurses ask most often?

Experienced reps expect a predictable set of questions and prepare clear, IFU-based answers:

• Which clamps should be closed before moving the patient, and in what order are they reopened?
• How is the system re-leveled after the head of the bed changes?
• What does the system look like when it is draining normally, and when it is not?
• How often should the bag be changed, and what is the maximum fill?
• Is the catheter standard or antibiotic-impregnated, and how can the nurse tell?
• Does the same system work with a lumbar catheter on this unit?

For the last question, the EVD-020 Series is designed for use with a ventricular or lumbar catheter, and the lumbar drainage catheter kit provides an 80 cm silicone catheter for external lumbar drainage. If the unit manages lumbar drains, include a short segment on that setup.

What belongs on the quick-reference sheet?

The quick-reference sheet is what nurses will actually consult at 4 a.m., so it deserves as much care as the session itself. Keep it to one side of one page, use the same words as the Instructions for Use and include only device facts. A useful sheet contains:

• A labeled diagram of the assembled system, with each clamp numbered.
• The component list with key facts, for example the 30 cm scale, 150 ml drip chamber and 800 ml bag on the EVD-010 Series.
• How to tell the orange antibiotic-impregnated catheter from the standard version.
• The bag change sequence in numbered steps, copied faithfully from the IFU.
• Where to find the full IFU on the unit and how to reach the rep and the manufacturer.

Ask the nurse educator to review the sheet before it is printed. Many hospitals have their own sign-off route for unit documents, so build that time into the plan rather than arriving with a finished laminate on day one.

How do you show the difference from the current system?

Most nurses in the room already know another EVD. The quickest way to build confidence is a side-by-side walk-through: where the zero line is on each scale, how each drip chamber empties, where the clamps sit. Avoid criticizing the incumbent product. Simply state the differences so nurses can map their existing habits onto the new setup, and flag any step where a habit from the old system could lead to an error on the new one.

How do you reach every shift?

A single afternoon session misses most of the staff. Plan sessions at shift change, offer early morning and late evening slots, and arrange coverage for weekends. Train super-users on each shift who can support colleagues when the rep is not there. Leave the quick-reference sheet at each nursing station and attach a small laminated version near the supply area.

What should happen after day one?

Follow up within the first week. Ask the educator what questions came up, visit during the first placements if the hospital allows it, and log any issue in writing. Feed product questions back to the manufacturer. DESU manufactures its EVD systems in its own facility in Ankara, Türkiye, so questions about components and IFU wording go directly to the team that designed them.

A short written summary to the nurse educator after two weeks, listing questions raised and how they were answered, builds trust and gives the value-analysis committee evidence that the product was supported properly.

Plan a refresher at the one-month mark as well. By then nurses have used the system enough to have real questions, new staff have joined and the super-users can tell you which steps still cause hesitation. A ten-minute refresher focused on those steps does more than a second full session.
