Abdominal wall blocks are an effective regional anesthetic technique to provide sufficient analgesia in abdominal surgery. This article reviews the use of abdominal wall blocks in pediatric regional anesthesia.

The introduction of nerve stimulation as a method of nerve localization sparked a new beginning in regional anesthesia. It was an epochal development akin to the utilization of ultrasound in more recent times. ⋯ Both of these technologies allow for only limited elucidation of needle position relative to the target nerve and are unable to reliably identify intraneural position of the needle. This article will review the role of nerve stimulation in modern regional anesthesia techniques in light of the introduction of ultrasound technology.

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 Newer techniques have now superseded pediatric epidural analgesia (PEA), being as effective and safer, especially with the advances in ultrasonography.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.
