Pediatric regional anesthesia continues to evolve. Education and attention to anatomical detail remain key elements to successful outcomes. New techniques, some adapted from adult practice, provide analgesia for pediatric surgical procedures such cleft palate or congenital hip dysplasia. Despite technological advances a number of controversial issues remain unresolved.

The future of pediatric anesthesia can be thought of in terms of what will happen to the practice of anesthesia, or what will happen to the profession of pediatric anesthesia. The profession will change both under external forces, and by how pediatric anesthetists themselves decide to shape of the profession. The largest external force is likely to be cost. ⋯ New technologies will have an impact in monitoring and in the gathering and dissemination of information. Practice will also change with changes in surgery. Perhaps the biggest changes will come in areas with the greatest unknowns; neonatal anesthesia is an area with many unknowns and thus great potential for change and improvement.

The accurate assessment of the depth of anesthesia, allowing a more accurate adaptation of the doses of hypnotics, is an important end point for the anesthesiologist. It is a particularly crucial issue in pediatric anesthesia, in the context of the recent controversies about the potential neurological consequences of the main anesthetic drugs on the developing brain. The electroencephalogram signal reflects the electrical activity of the neurons in the cerebral cortex. ⋯ However, the cortex is only one of several targets of anesthesia. Hypnotics and opiates, have also subcortical primary targets, and the EEG performances in the evaluation or prediction of nociception are poor. Monitoring subcortical structures in combination with the EEG might in the future allow a better evaluation and a more precise adaptation of balanced anesthesia.

ReviewDuctal ligation in the very low-birth weight infant: simple anesthesia or extreme art?
Management of the very low-birth weight infant in the neonatal intensive care unit (NICU) is geared to provide optimal outcome not only in term of survival but increasingly with a goal of limitation of long-term neurological and pulmonary morbidities. Careful follow-up studies have demonstrated that relatively small variations in oxygenation and gas exchange, ventilator management, and other management modalities can have long-term consequences. ⋯ Does the anesthetic management matter? Given the attention to detail within the NICU, it would seem prudent to try to choose techniques that limit changes in hemodynamics, gas exchange, and ventilation within the context of the surgery. Anesthesia for ductal ligation in the very low-birth weight infant may need to be judged by more than simple survival and brings into question the current techniques and monitoring used.
