Preparing for your Video-EEG monitoring (EMU) Admission

Admission to hospital
On the day of admission to hospital please report to Walter Reed National Military Medical Center in the Eagle building 10 the first floor, Admitting Department around 0730 to check-in. If you are an Adult, you will be sent to the Epilepsy Monitoring Unit (EMU) on the 4th floor of the Eagle building 10 where you will stay for the monitoring session. If you are a Child/Adolescent you will be sent to the Epilepsy Monitoring Unit (EMU) on the 3rd floor of the Eagle building 10 where you will stay for the monitoring session. The EEG Laboratory on the 6th floor in the America building 19; is where you will have electrodes placed on your scalp for video-EEG monitoring. After the electrode placement you will go back to the EMU. (Please remember to come in with your hair free from any braids, weaves, spray, mousse, grease, or gel, just as you would for any EEG.)

A primary nurse will be assigned to you to plan all of your nursing care. The doctor or nurse will place a heparin lock (intravenous catheter) in a vein in your hand or arm. This is for your safety should you require any intravenous medication due to increased seizure activity. Visitors are welcome, and arrangements can be made for family members to stay with the patient.

Video-EEG monitoring tends to be quite boring, so please feel free to bring any books, needlework, cards, board games, or anything you enjoy doing that will help pass the time. The hospital offers free WiFi and each room is equipped with a telephone and television. Bring pajamas and comfortable clothing. Bring clothing that buttons down the front rather than clothing that goes over the head. Bring personal toilet articles such as a toothbrush, toothpaste, hand cream and etc. Please do not bring any valuables with you. The medical center cannot be responsible for money or valuables that are not stored in the medical center safe.

Also, please remember that this is a non-smoking institution. We may prescribe a nicotine patch if medically needed. Should you have any other questions about your stay here at Walter Reed National Military Medical Center, please do not hesitate to contact us at 301-295-4771 option 3 or 301-400-1862.

Some seizures, as you know, may cause injury. You need to be within the range of the camera as much as possible because we need to see your seizure activities. You cannot leave your room unless you are being sent for a special test such as an X-ray or scan. Depending on the severity and frequency of your seizures, you may need to stay in bed with the padded side rails up. In this case, you may need to have a nurse, aide, or other family member present for your bathroom trips or whenever you are out of bed. During the time you are being monitored, you will not be allowed to shower or wash your hair. You will be able to wash up from a basin in the bathroom or at your bedside. You will be able to shower and wash your hair after the monitoring is completed.

The length of your stay depends on the time needed to properly monitor your seizure activity. Although this varies among patients, a frequent length of stay is usually one week. We discuss your progress with you daily. Your doctor will meet with you to discuss your results after all the information has been reviewed. If were referred by another doctor, a formal report will be sent to him/her as soon as the information has been analyzed.
