outside hospital. WARNING AND PRECAUTION Halothane can induce liver damage. Minor changes in serum amino-transferase activity have been reported to occur in up to 30% of patients. The incidence of severe liver damage (jaundice, which may lead to hepatic failure as a consequence of massive hepatic cell necrosis) is much rarer but cases requiring liver transplants and fatalities have been reported. The risk of developing hepatic failure appears to be greatly incrased by repeated exposure to halothane. Although short intervals of time between exposures are likely to increase the risk of hepatoxicity, even long intervals between exposure may not reduce the risks, since some patients have developed severe reactions to halothane given many years after the previous exposure. Other risk factors for hepatotoxcity include female gender, obesity, middle age and a history of drug allergy on present available information, the following precautions should be taken: 1.A careful anesthetic history is to be taken from patients due to undergo anesthesia in order to determine whether exposure to halothane took place and the nature of any adverse reaction to this agent. 2.History of unexplained jaundicie or pyrexia after a previous exposure to halothane is an absolute contraindication to its future use in that patient. 3.Further exposure to Halothane within three months is to be avoided unless there are overriding reasons for its re-use. 4.Patients who have exhibited adverse reactions to halothane should be informed and strictly instructed to alert their Physician. Details of the reaction should be entered on the patient's medical records. A rise in CSF and / or intracranial pressure might occur during neurosurgery, the effects of which may be mitigated by the use moderate hyperventilation.
