Over the past decade, numerous preclinical and retrospective human studies have reported that the provision of anesthetic and sedative agents to infants and children may be associated with adverse neurodevelopmental outcomes. These data have gained widespread attention from professional and regulatory agencies, including the public at large. ⋯ To impart a framework from which anesthesiologists may address the apprehensions of parents who actively bring up this issue, we review the data supporting anesthetic neurotoxicity and discuss its strengths and limitations. As many parents are not yet aware and do not actively raise these concerns, we also discuss whether such a conversation should be undertaken as a part of the consent process.

ReviewAnesthesia and long-term outcomes after neonatal intensive care.
As survival is now increasing, care of the extremely preterm infant is now directed at strategies to minimize long-term morbidity. In this study, I review the current state-of-the-art outcomes for babies born at extremely low gestations and identify strategies that may be aimed at optimizing outcomes. With respect to anesthetic practice, I then go on to discuss important issues of pain management in these babies and how this may affect long-term outcomes.

ReviewLimitations and vulnerabilities of the neonatal cardiovascular system: considerations for anesthetic management.
Development of the cardiovascular system through the last trimester of pregnancy and the subsequent neonatal period is profound. Morphological changes within the myocardium make the heart vulnerable to challenges such as fluid shifts and anesthetic drugs. ⋯ There is now a better understanding of the limitations of blood pressure homeostasis in the neonate and the potential consequences of marginal hypoperfusion. This article highlights some of these vulnerabilities particularly as they relate to anesthesia and surgery in the very young.

ReviewBeyond survival; influences of blood pressure, cerebral perfusion and anesthesia on neurodevelopment.
Neonates have a higher perioperative mortality risk largely due to the degree of prior illness of the infants, the complexity of their surgeries, and infant physiology. It is important to consider contributing anesthetic factors during the perioperative period that may affect cerebral perfusion and neurocognitive outcome, such as alterations in hemodynamics and ventilation. Limitations of blood pressure as a marker for cerebral perfusion are discussed, as well as the effect of hypocapnia on the brain.

Neonatal anesthesia is fraught with potential risk for the patient and stress for the anesthesiologist. Where possible, recognition of these risks, avoidance of, and being able to manage them appropriately, must impact positively on perioperative outcomes in this vulnerable group of patients. Good communication with the parents, as well as with other healthcare providers, is crucial to safe and successful anesthetic care.
