The Authors analyse and discuss some particular problems related to anaesthesia in neurosurgery according to the patient's clinical and neurological status and to the surgical treatment. The evaluation of systemic and neurological physiopathology during pre-, per- and post-operative periods are important for this analysis. Therefore anaesthesia and intensive care methods are attentively discussed. Intracranial pressure, cerebral blood flow, metabolism, intracranial space-occupying lesions and surgical techniques are the main factors interfering with anaesthesia in neurological surgery.

Case ReportsEnflurane-induced grand mal seizures during otic microsurgery.
Abnormal electroencephalographic seizure-like activity and myoclonic movements have been recognized during enflurane anesthesia. This is most commonly seen in the presence of respiratory alkalosis and high concentrations of enflurane. ⋯ Experimental studies have shown that auditory stimuli could facilitate seizure activity during deep enflurane anesthesia. Here we report a case of intraoperative generalized tonic-clonic convulsion during low concentrations of enflurane without evidence of hyperventilation and the presence of auditory stimulation.
