对合并肺功能不全病人的术前评估，应对个人的具体情况作出判断，以降低手术的风险。包括：6min步行试验、胸部CT检查、肺通气功能、肺弥散功能、放射性核素肺通气、肺血流灌注显像及运动性心肺功能检查等有助于做出正确的判断。最稳妥的办法是术前心脏、呼吸及麻醉专业的医生共同评价手术风险及预后。

Preoperative physiologic assessment for patients with respiratory insufficiency        SHEN Ce. The Sixth People Hospital of Shanghai Jiao Tong University, Shanghai 200233, China
Abstract    The physiologic assessment of patients with respiratory insufficiency should be considered for surgery in order to reduce the postoperative pulmonary complications. The examinations help preoperative risk assessment of the patient. They are the 6min walk, chest CT，pulmonary function test, ventilation and perfusion lung scanning，Doppler venous flow detection and cardiopulmonary exercise testing. The best method for preoperative risk assessment is that pulmonologist, cardiologist, anaesthetist and surgeon discuss the surgery risk and prognosis together.
