IV Regional Block

An IV regional block is a procedure used in the treatment of Complex Regional Pain Syndrome (CRPS). Complications are rare, but can include blood pressure changes and weakness and numbness in the affected area. Many patients experience pain relief for two to 14 days and some may even have long-lasting pain relief after several injections.

You will need a ride home. No driving for 3 hours after the procedure due to the side effects of medications given.

When you arrive, a nurse will obtain a description of your pain and how you are managing daily activities. Medications, allergies and a brief health history will be reviewed. Your blood pressure, pulse, temperature and weight will be recorded. For your safety, you will be asked to get onto a stretcher and an IV will be placed in the hand or foot, depending on where your pain is located.

After discussing treatment with your physician and signing procedural consent, the medications will be injected through your IV. A tourniquet will be left in place for 30 minutes to keep the medication in the area to help block or decrease your pain. We will try to make you as comfortable as possible.

You will be closely monitored for the effects of the medication, which can affect your heart, blood pressure and may make your arms or legs feel weak or numb. You might also notice some temporary lightheadedness and nausea. A nurse will be available to answer any questions you might have and to review discharge instructions and follow-up care.

When you go home

  • Activities: Rest and avoid activities that might aggravate your pain. You can usually return to work and exercising on the next day. No driving for three hours.
  • Pain: Apply heat or ice to your area of pain. Your regular pain medications will help with any discomfort. Relief may last from days to weeks.
  • Follow-up: Call if you develop a fever, chills, redness, swelling or drainage at the treatment site. Make an appointment for follow-up or to repeat the procedure as needed.

Many patients will begin to have pain relief after several procedures. Don’t be discouraged! Talk with your physician.
