1 What is Critical Care Medicine? Xixiuming ICU Fu Xing Hospital 2012

2 ICU 概念的起源 …… 英国护士 Florence Nightingale 被认为是第一个使用 ICU 概 念的人 Crimean War,1854 to 1856 她 把最终的伤员集中在护士站 周围,以便看到患者病情变 化,可以迅速提供所需的医 疗服务

3 Intensive care medicine owes its roots to the support of failing ventilation 呼吸支持 Intensive Care Medicine 的根 呼吸支持 脊髓灰质炎导致的呼吸衰竭 吸入麻醉后的呼吸管理 RICU SICU Crit Care Clin 25 (2009) 239–250 General ICU 多器官生命支持

4 呼吸 ICU 的开始

5 历史回顾 -The first ICU in the world Acta Anaesthesiol Scand 2003;47: Bjorn Ibsen 第一次使用正压通气治疗 呼吸衰竭的医生 ( In the first ICU in the world ) 这项新技术的应用是病死率从 的 87% 下降到 的 15% 因此 1953 年 3 月是机械通气的生日

6 Controlled Respiration by Means of Special Automatic Machines as Used in Sweden and Denmark The treatment of ventilatory insufficiency after pulmonary resection with tracheostomy and prolonged artificial ventilation J Thorac Surg 1955;30(3):356–67 Engstrom had already demonstrated the advantage of his ventilator in the treatment of totally paralyzed polio victims during the Copenhagen epidemic Acta Anaesthesiol Scand 1963;(Suppl 13) McKesson machine with Trier Moerch's "Respirator".

14 Intensive care medicine comes of age Julian Bion and Timothy Evans  Sub-specialty of one or more disciplines  ‘Supra-specialty’ (an add-on with common skills across all)  Primary specialty There is considerable overlap in content between the supra-specialty and primary specialty models Clinical Medicine 2011,vol 11,6:519-20
