耳鼻咽喉科領域に於けるトリクロールエチレン吸入麻酔の使用経験

　Ⅰ．緒言

　最近の麻酔学の進歩により，耳鼻咽喉科領域にも，種々な麻酔方法がとり入れられつゝあるが，或は人手を要し，或は時間的，経済的に大がかりになる為依然として，局所麻酔のみに頼つて，患者に或程度の疼痛は我慢させて居る場合が多く，殊に小児に於いては，その為に手術の進行がさまたげられたり，不完全に終つたりする事があつた。さきに，山下氏は，主として産科，婦人科領域に於いて用いられて居た，トリクロールエチレン（トライレーン）吸入麻酔を，疼痛を伴う手術や処置の多い耳鼻咽喉科領域に応用し，簡単，且，安全で，人手も時間も要せず，有痛処置や小手術の麻酔として，非常に便利である事を紹介された。

　今回私共は，以上の事を追試すると共に，2，3の考案を加え，応用範囲を拡大する事に成功したので，こゝに御報告する次第である。

Niho and Ida make a report of their experie-nce in use of trichlorethylene as inhalation ane-thesia for various operative procedures, major and minor, including even those consisting of after-treatment of operation, insufflation of au-ditory tube and X-ray examinations, where ane-thesia is necessiated or desirable for tranquility of the patient for successful execution of the particular procedure.

Where ordinary anesthesia mask is both cu-mbersome and a hindrance to procedures to be adopted in the nose, mouth and throat, suthors devise masks, oral or nasal use, to meet the occasion that may be required. With these amar-mentarium the use of anesthesia is, thereby, not only facilitated but also broadened in its application.

The present method is simple in application, safe in execution, and economical because it require no extra personnel. It has very little side-effects: relatively free of tracheal inspira-tion of foreign body because laryngeal reflex is preserved without a loss. In minor operations where sitting-position is perfereable, due to the fact that muscular tonus being preserved throu-ghout the anesthesia, such a position may be maintained during the procedure.
