鎮静薬,麻酔薬の鎮静・催眠作用はGABA受容体を介したものと考えられているが,鎮静薬,麻酔薬には中枢でのアデノシンを増加させる作用もある.本研究では,アデノシンによる神経伝達物質調整作用の健忘効果に与える影響を評価した.鎮静深度が浅い状態にアデノシンの前駆物質であるアデノシン三リン酸を投与すると鎮静作用とともに健忘効果が増強された.また,深鎮静時にアデノシン受容体の拮抗薬であるアミノフィリンを投与すると,鎮静効果とともに健忘効果も拮抗された.このことから,アデノシン受容体の刺激は鎮静効果の増強とともに健忘効果を増強し,アデノシン受容体の拮抗は鎮静効果と健忘効果を拮抗することが示された.

Dissociative identity disorder (DID) is characterized by the existence of two or more separate and distinct personalities on an ongoing basis. Although the incidence of DID has been increasing in Japan, dental treatments for such patients remain rare. Here, we report our experience providing general anesthesia to a patient with DID and generalized anxiety disorder.  A 30s woman had been diagnosed as having DID at the age of 24 years, and her condition was being managed with medication. Although more than nine personalities had appeared as of the presently reported treatment, her original personality had not appeared for several years. She had numerous dental caries and an extreme fear of dental treatments. Therefore, we planned to perform dental treatments under general anesthesia.  Anesthesia was maintained with 3.0 μg/ml of propofol and 0.05-0.1 μg/kg/min of remifentanil hydrochloride. Since DID patients can respond to anesthetics differently than healthy adults, we used a BIS monitor to ascertain the depth of the anesthesia. Furthermore, the dentists, nurses, and other staff members shared information during the perioperative period. As a result, while changes in the patient’s personality were observed, no serious mental disturbances occurred.
