The caudal approach to the epidural space was first reported in 1901. Injection of steroids to treat low back pain was introduced in 1952. ⋯ Caudal epidural injections are associated with inaccurate needle placement when performed blindly in a substantial number of patients, resulting in intravascular injections as well as other complications. This review will discuss anatomic and technical considerations of caudal epidural injections, along with advantages, disadvantages, complications, and indications.

Spinal pain is an important public health problem affecting the population indiscriminately. The structures responsible for pain in the spine include the vertebrae, intervertebral discs, spinal cord, nerve roots, facet joints, ligaments, muscles, atlanto-occipital joints, atlanto-axial joints, and sacroiliac joints. Even though disc herniation, facet joints, strained muscles, and torn ligaments have been attributed to be the cause of most spinal pain, either in the neck and upper extremities, upper and mid back, or low back and lower extremities, disorders of the disc other than disc herniation have been implicated more frequently than any other disorders. ⋯ The three primary components of diagnostic disc injection are: provocation/analgesia, discometry, and nucleography. Despite the recent exponential growth of noninvasive spinal technology, diagnostic disc injection remains the sole direct method for definitively determining whether a disc is a physiological pain generator. It is clear that discography is a safe and powerful complement to the overall clinical context.

Over the years, ketamine has found many applications in paediatric anaesthesiology. Recent insights into the mechanism of its central action, and the pharmacology of its isomers have led to a re-evaluation of this drug, expanding the range of indications in adults. The best examples of the uses of ketamine as an analgesic are: in brief diagnostic or therapeutic procedures, during the post-operative period in neonates and infants as well as in paediatric anaesthesia and intensive care.
