Definitions

  • the invention relates to the use of galanthamine and its derivatives for the manufacture of medicaments for the treatment of postoperative delirium.
  • delirium A state of disturbed consciousness characterized by general confusion, a decrease in cognitive functions (attention, concentration and memory), hallucinations and unstable emotions. This means that the delirium exhibits elements of dementia as well as psychotic state images, but is mainly due to its acute nature and the mostly spontaneous, though often incomplete and delayed, reversibility delimited. Unlike degenerative dementia syndromes, postoperative delirium is exclusively a functional disturbance of the central nervous system Clinical picture generated by psychiatric symptoms can fluctuate very quickly - occasionally within seconds. Acute or subacute delirium (according to the World Health Organization classifications ICD 293.0 and 293.1) is often induced by taking pharmacologically active substances.
  • drugs with an anticholinergic effect which partially block the nervous system based on the neurotransmitter acetylcholine, can induce delirium, but also sedatives, such as benzodiazepines, and antimanics, such as lithium salts.
  • Intoxicants or their acute withdrawal after chronic use can also cause delirium. This is very often the case with massive acute alcohol abuse or alcohol withdrawal (ICD 291.0), but cannabis products, amphetamines, cocaine etc. can also cause delirious conditions.
  • Postoperative delirium is now regarded as a multifunctional syndrome i 1 ), whereby the age and general health of the patient play a role as well as any preoperative cognitive disorders, undefined influences of the anesthetics administered, and possibly also certain intraoperative ones physiological changes ().
  • a POD can be present immediately after waking from anesthesia, it is not the same as the rapidly passing benign disorientation after anesthesia.
  • a POD can only be used on the second postoperative day or even later after the actual awakening from the anesthesia has been clinically normal. In this case, a direct effect of the perioperatively administered anesthetics or analgesics can be excluded.
