自从党号召我们要树立敢想、敢说、敢做的精神,大闹技术革命以来,随着医疗事业的跃进,我院外科手术也有很多增加。过去所做的手术大都用局部麻醉,偶尔也用乙醚开放滴入麻醉。滴入麻醉的缺点较多,麻醉人员很费力;所用的乙醚浪费也较大,大约一、二个小时的手术,就需要200～300毫升的乙醚,仅从病人进入第三期——外科麻醉期(也称皮质下部抑制期),所耗乙醚就达60毫升左右;而且麻醉中的一个重 Since the party called for us to establish the spirit of dare to think, dare to say, dare to do, since the technological revolution, as the leap forward in medical services, there have been many increases in surgical operations in our hospital. Most of the surgery done in the past with local anesthesia, and occasionally with ether open drip anesthesia. Anesthesia has more of the disadvantages of instillation, the anesthesia personnel are laborious, the ether used is also wasted, and approximately one to two hours of surgery require 200 to 300 ml of ether, entering the third phase from the patient alone. Surgical anesthesia Period (also known as the lower cortical inhibitory period), consume about 60 ml of ether; and anesthesia in a heavy
