Caudal block

A caudal block is a medicine given in patients as an injection near the lower spine to reduce pain following the lower abdominal or groin-area surgery. A caudal block is also known as a caudal epidural block, the caudal block method, or a block caudal. It is a way of providing anesthesia. Caudal anesthesia is used to provide anesthesia and pain relief below the umbilicus. It may be the sole anesthetic for some procedures, or it may be combined with general anesthesia. A caudal block is used to suppress the nerve sensation entirely, in order to completely relieve the pain in patients. Caudal anesthesia has been used for many years and is the easiest and safest approach to the epidural anesthesia. If performed in the right way, there is no damage for the You do not have access to view this node.


What is Epidural Steroid Injection (ESI)?

An ESI is an ordinary type of injection that is given to offer relief from pain in low back and neck areas. The "epidural space" is the space between the covering of the spinal cord (dura mater) and the inside of the bony spinal canal. It runs the entire length of the spine. When injected into this area the medication moves freely up and down the spine to coat the nerve roots and the outside lining of the facet joints near the area of injection. For instance, if the injection is given in the lumbar spine, the medication will generally affect the total lower portion of the spine.


What is Cadual canal?

The caudal canal is the part of the spinal canal near the lower spine. A caudal block is given in the form of an injection into the caudal canal. Mostly, it is used to reduce the pain and distress due to the groin surgery or any type of surgery performed on the lower You do not have access to view this node. The patient will be given another form of pain medication to treat discomfort after the caudal block has lost its effect.


How is the caudal procedure performed?

  •  Normally, the caudal block procedure takes about 15 to 30 minutes to finish.
  •  It is carefully performed under fluoroscopic (x-ray) control in order to increase the precision of the block.
  •  The patient is asked to lie face down on a cushioned x-ray table and the skin is prepped with an antiseptic.
  •  Next, the skin is numbed with local anesthetic.
  •  A small needle is used to inject a local anesthetic (numbing medication) into the area where the injection will be administered; this may sting for a few seconds
  •  Next, a needle is placed in the tailbone area, and dye may be injected to confirm correct location of the needle tip with the assistance of fluoroscopy.
  •  A solution of local anesthetic and a cortisone derivative (anti-inflammatory medication) is then injected.
  •  The needle is removed and a gauze dressing will be placed.
  •  The block usually helps ease the pain for about 6 to 8 hours after You do not have access to view this node, and sometimes even up to 10 hours.


What is the recovery time?

  •  Following a caudal block, the patient will slowly regain sensation within 4 hours to 6 hours.
  •  After the procedure, the patient is able to move his/her legs but may feel weak or numb.
  •  The patient should not walk without assistance for the first 8 to 10 hours after the operation.
  •  Occasionally, the patient may not feel heat on his/her stomach or legs until the caudal block has worn off in about 8 to 10 hours.


Who needs a caudal block?

  •  Caudal blocks are generally used for analytic and therapeutic purposes.
  •  A caudal block provides pain relief for children who have operations below the belly button.
  • Caudal blocks are generally used in younger children (less than 10 yrs old) for operations in the inguinal area or lower part of the body (below the belly button).
  •  These are commonly urologic, pediatric surgical or orthopedic procedures.
  •  The diagnostic blocks are offered to try and also establish precisely the reason for the structural abnormality that is causing the symptoms. This is process is also known as determining the 'pain generator'.


What are the uses of caudal block?

  •  With a caudal block, only a small amount of anesthesia is required during the surgery which allows for a faster recovery and waking time. The numbness from the caudal block will decrease the pain after the You do not have access to view this node.
  •  The caudal block is an easy and safe way to provide anesthesia and post-operative analgesia for various surgical procedures.
  •  It is used to relieve the labor pain in women.


What are the risks of caudal block?

The probable difficulties in this procedure include:

  •  Intravascular injection
  •  Dural puncture
  •  Puncture of the rectum
  •  Sepsis, urinary retention
  •  Subcutaneous injection
  •  Hematoma and
  •  Absent or patchy block.


What are the side-effects?

  • General side effects include increase in the normal amount of pain or experiencing new pain that will ultimately resolve within one to ten days. These reactions are known as "flares" and are rare.
  •  In addition, adverse reactions to the corticosteroids which do not normally occur and are only temporary even if they do occur. These include headaches, euphoria, depression, swelling, skin rash and even changes in menstrual regularity.
  • More serious problems such as infection or severe allergic reactions, strokes, or heart attacks can hypothetically occur at a frequency of about one in ten thousand injections.
