Review Comparative StudyOccupational exposure to anaesthetic gases: a role for TIVA.
Modern anaesthesia is still mostly administered by the inhalational route and there is increasing concern over its potential for pollution. One of the first gaseous anaesthetic agents was nitrous oxide and this is still widely used today despite being associated with adverse effects caused by depression of vitamin B(12) function and diminished reproductive health. The use of halothane is associated with hepatitis but the adverse effects of newer halogenated hydrocarbons are less well recognised. ⋯ Levels of inhalational anaesthetics in the ambient air of operating theatres and recovery rooms often exceed those stated in national guidelines. Anaesthetic procedures can be modified and air-conditioning and air scavenging systems should be used to minimise the risks from occupational exposure and threats to the environment. Such contamination could be avoided with the use of total intravenous anaesthesia.

ReviewCyclosporine A for neuroprotection: establishing dosing guidelines for safe and effective use.
Numerous neuroprotective compounds have been investigated to ameliorate secondary changes and the progression of injury after the primary insult in traumatic brain injury (TBI). This cascade of events is complex and difficult to abate once initiated following the primary injury. The clinical consequences of this secondary injury are unpredictable and often permanently incapacitating. ⋯ This review discusses the physiologic responses following TBI that may affect CsA efficacy and safety when used for neuroprotective indications. So far, CsA seems to be safe in the TBI population. The role of CsA after acute TBI will be better defined after the completion of upcoming planned clinical trials.
