[Potential Neurotoxicity of General Anaesthetics to the Developing Brain]

Animal studies (including non-human primates) have shown that most general anaesthetics cause enhanced neuroapoptosis with subsequent long-term neurocognitive deficits later in life. Some human cohort studies have indicated an association between anaesthesia/surgery and adverse neurocognitive outcome whereas other studies have not. Overall, the data do not justify any change in paediatric anaesthetic clinical practice. Naturally, the risks and benefits of a procedure should always be carefully considered before exposing a child to general anaesthesia.
