chloroformer

To anesthetize someone with chloroform — a once-standard 19th-century medical technique, now remembered mainly as a stock device in crime fiction and thrillers for rendering a victim unconscious.

• Le chirurgien chloroformait ses patients avant l'ère de l'anesthésie moderne. — The surgeon used to chloroform his patients before the era of modern anesthesia.
• Dans le roman, le voleur chloroforme le gardien de nuit. — In the novel, the thief chloroforms the night watchman.
• On ne chloroforme plus personne aujourd'hui ; l'anesthésie a bien évolué. — No one is chloroformed anymore today; anesthesia has come a long way.

This is a historical/fictional verb, not a modern medical one — real anesthesia today uses entirely different drugs and methods, so chloroformer belongs to period pieces and thrillers, not a contemporary hospital scene.
