What is it?
RACZ procedure is used to dissolve some of the scar tissue from around entrapped nerves in the epidural space so that medications can reach the affected areas. To numb and break down the adhesions, a local anesthetic (numbing medication) is administered. This procedure is also used to deliver medication to a specific site with the aid of the catheter. A special needle and catheter are inserted into the affected area. A specialized x-ray (fluoroscopy) is used to confirm placement. Medication is then used.
What are the expected results?
The major goal of the procedure is pain relief. You may be sore for a day or so. As the steroid used in the injection is a time-release medication, it may take 3-10 days for you to notice pain relief.
How long will it take?
The procedure itself only takes 15-30 minutes to perform. You will be observed in the recovery room for 30-60 minutes after the procedure.
What happens after the procedure?
Most often you can go home in about 30-60 minutes. Written instructions will be sent home with you. You will need someone to drive you home and care for you for the first few hours after the procedure. It is recommended that you take it easy for the rest of the day.
What to expect the day of your procedure?
You are expected to arrive at the surgery center at least one hour before your procedure is scheduled. Bring a responsible adult driver with you because you may be receiving medications that could impair your ability to drive. Unless you are certain you will not be receiving sedation, do not eat anything for 6 hours prior to your procedure; you may have modest amounts of clear liquids (liquids you can see through) up to 4 hours beforehand. Please take your regularly scheduled blood pressure, heart, asthma, long-acting narcotic and nerve pain medications with sips of water as you normally would. If you have diabetes, take half of your normal dosage and bring your insulin with you. Be sure to discontinue aspirin products and any other blood thinners as instructed.
After you arrive, you will be asked to sign-in and complete any paperwork as needed. You will then be taken to the preoperative area. At this time, a nurse will ask you some medical questions and have you sign your consent forms. It is imperative that you, the patient, inform the assistant of any changes in your history and/or physical, such as recent flu or any health problems that might affect your procedure. Inform the staff of any allergies, especially to Betadine or Iodine.
You may be asked to change into a gown. An assistant will take your vital signs and an IV may be started in order to provide pain relief and relaxation.
The physician and nurse will talk to you before your procedure. In certain cases, an anesthesiologist may also be utilized. You will then be positioned and the injection sites will be prepped. Your pain management physician will perform the procedure. Medications may be administered before and during your procedure to help you relax and provide pain relief. You may doze off during this time. Afterward, bandages will be applied as needed.
You will be transported to the recovery room area where you will be monitored anywhere from 30 minutes to an hour. You will be offered beverages and some crackers. After this, someone will take out your IV and help you get dressed if needed. Lastly, your caregiver will be given discharge instructions for your care at home.
