Abstract:

Multiple chemical sensitivity syndrome is a group of complex disorders that include psychiatric disorders , chronic fatigue and/or respiratory problems . This syndrome could be triggered by specific allergens and toxins that cause neurophysiological sensitization and the appearance of the clinical symptomatology . Anaesthesia for these patients always poses a challenge for the anaesthetist , because they need to find and use drugs that do not trigger or aggravate the symptoms of the disease . Therefore , sevoflurane in these circumstances might be “the ideal anaesthetic” . Performing general anaesthesia with sevoflurane as the sole anaesthetic agent , together with a series of environmental measures formed the basis for successful anaesthesia and surgery in our patient with a multiple chemical sensitivity syndrome .
