Anaesthesia for patients with idiopathic environmental intolerance and chronic fatigue syndrome

We suggest that the anaesthetist may be best to use the technique they would use if the patient did not have CFS or IEI but avoid drugs to which there is a history of adverse response. Anaesthesia is likely to be associated with adverse effects in these patients but the effects are not likely to be severe. A series of recommendations for the safe and harmonious conduct of anaesthesia in patients with CFS and IEI are provided.
