What is a caudal block?
A caudal block, also referred to as a caudal epidural injection, is a steroid injection that is administered through your caudal canal in your lower back. This procedure is done to help alleviate lower back pain as well as leg pains caused by a range of conditions including sciatica, bone spurs and herniated discs. A type of x-ray machine called a fluoroscope is used to assist the surgeon to locate the affected nerves.
How does the procedure work?
For this procedure you may be given a conscious sedation through an intravenous tube in your arm. This medicine will help you to relax during the procedure. You will lie face down on an x-ray table for the procedure. Your surgeon will inject a local anaesthetic into the affected area on your lower back. When the area has been numbed, an injection containing a dye will be injected into the affected nerve roots with the help of a fluoroscopy. This dye is used to ensure the correct location of the steroid injection. Finally an injection containing another local anaesthetic and an anti-inflammatory medicine is administered to the affected area. A small gauze dressing will be placed over the injected area. The entire procedure is rather quick and should take no longer than 30 minutes. You will be discharged on the same day.
