WebbOver the past 25 years, the PI of inhaled anesthetics decreased by 52 %, and that of intravenous anesthetics fell by 32%. At the same time, the PI of anesthesia management increased by 167%. Among individual anesthetics, the most impressive change was a profound decline in halothane’s PI, from 22.9 in 1972-1976 to 0.5 in 2012-2016. WebbAbstract. Inhalational agents have played a pivotal role in anesthesia history. The first publicly demonstrated anesthetic of the modern era, diethyl ether, was an inhalational anesthetic. The attributes of a good agent, ability to rapidly induce anesthesia, with limited side effects has led research efforts for over a hundred and fifty years.
