Paediatric anaesthesia
-
The pediatric epidural is an accepted method of advanced analgesia in children. Newer techniques have now superseded pediatric epidural analgesia (PEA), being as effective and safer, especially with the advances in ultrasonography. PEA is, however, still an important technique to master and employ, and it may be that the indications for this mode of analgesia have now become more defined.

Review Historical ArticleHistory of pediatric regional anesthesia.
The history of local and regional anesthesia began with the discovery of the local anesthetic properties of cocaine in 1884. Shortly afterwards nerve blocks were being attempted for surgical anesthesia. Bier introduced spinal anesthesia in 1898, two of his first six patients being children. ⋯ Spinals and other local techniques had periods of greater and lesser use and have not been universally employed. Initial loss of popularity seemed to relate to improvements in general anaesthesia. The advent of lignocaine (1943) and longer acting bupivacaine (1963) and increasing concern about postoperative analgesia in the 1970-1980s, contributed to the increased use of blocks.

ReviewToxicity of local anesthetic drugs: a pediatric perspective.
The main mechanism of action of local anesthetics (LA) is to block sodium channels, thereby interrupting the propagation of nerve impulses. However, this action not only is localized to the sodium channels of nerve tissues involved with pain transmission but will have its effect on any tissue containing sodium channels. ⋯ The two most important tissues associated with systemic toxicity of LA are the central nervous and the cardiovascular systems, which may lead to seizures, tachyarrhythmias, and ultimately death from apnea and cardiovascular collapse. The aim of this communication is to elucidate some issues that are associated with toxicity of LA and its treatment in the pediatric population.

Every anesthetist should have the expertise to perform lumbar puncture that is the prerequisite to induce spinal anesthesia. Spinal anesthesia is easy and effective technique: small amount of local anesthetic injected in the lumbar cerebrospinal fluid provides highly effective anesthesia, analgesia, and sympathetic and motor block in the lower part of the body. The main limitation of spinal anesthesia is a variable and relatively short duration of the block with a single-injection of local anesthetic. ⋯ Most children having surgery with spinal anesthesia need sedation, and in these cases, close monitoring of sufficient respiratory function and protective airway reflexes is necessary. Postdural puncture headache and transient neurological symptoms have been reported also in pediatric patients, and thus, guardians should be provided instructions for follow-up and contact information if symptoms appear or persist after discharge. Epidural blood patch is effective treatment for prolonged, severe headache, and nonopioid analgesic is often sufficient for transient neurological symptoms.

Caudal anesthesia is the single most important pediatric regional anesthetic technique. The technique is relatively easy to learn (1), has a remarkable safety record (2), and can be used for a large variety of procedures. The technique has been reviewed in the English (3) and French (4) literature, as well as in German guidelines (5) and in pediatric anesthesia textbooks (6).
