Minor short-term depression of mental function is seen after anaesthesia and surgery. However, general anaesthesia does not seem to cause permanent damage or depress mental function beyond the first 2-4 postoperative days and no significant advantages of regional anaesthesia, as regards to cerebral function, are found after this period. ⋯ The risk of mental disturbance is increased in patients with psychiatric disease or presenile dementia and may be due to ongoing treatment with tricyclic antidepressant and neuroleptic drugs. Centrally acting cholinergic drugs, hypotension and hypoxia together with postoperative pain and sleep deprivation should be avoided.

Review Randomized Controlled Trial Clinical Trial
[Intraoperative awareness in balanced anesthesia. A literature review based on a randomized double blind study using fentanyl, pentazocine and ketamine].
Since the first case report by Winter-bottom [106], the problem of intraoperative awareness or recall has received increasing attention from patients, anaesthesiologists and, more recently, even law courts [4, 20, 21, 78]. Our own interest in awareness derives from a study with the opiate agonist tramadol as a supplement to balanced anaesthesia, which revealed an unexpectedly high incidence of about 65% of patients who could recall intraoperative music [55]. It was the aim of the present randomized double-blind study to evaluate, under identical experimental conditions, what the incidence would be with other analgesic supplements to balanced anaesthesia (fentanyl, pentazocine and ketamine). ⋯ Recovery was fastest with F, followed by P, and slowest with K. Retrospective judgement of the quality of anaesthesia by the anaesthesiologist did not differ significantly between the treatment groups. Most (93%) of the patients were satisfied with their anaesthesia; 2 patients each who received P and K were dis

Nowadays approximately 20% of all patients operated are older than 60 years of age. So it seems to be interesting to investigate the effect on the increase of systemic disease of these patients, to estimate a proper anaesthesiological management. ⋯ Therefore preoperatively registration and therapy of these risks are necessary, however diagnostic evaluation cannot be standardized. There is no typical anaesthesia for the elderly.
