摘　　要：目的分析老年病人胸外科手术前后的动脉血氧变化。方法胸外科手术病人200例,按年龄分为二组,≥60岁老年组84例,60岁以下非老年组116例。术前呼吸空气,术后低流量吸氧(2L/min)。分别于术前、术后第一天和术后第三天抽取动脉血测定。结果术后低氧血症(PaO2<60mmHg)发生率:老年组为8.3%(14/84×2),非老年组为6.9%(16/116×2)。术后低氧血症发生于全肺切除组中仅一例,其余29例次低氧血症均发生于术侧有肺或余肺的手术组中。结论低氧血症发生率与年龄因素无明显相关,而与手术种类有关。一定限度范围内的肺功能损害不影响术前后静息状态下所测动脉血氧值。Objective To analyze the pre -a nd postoperativ e arterial blood oxygen for the elderly patients undergoing thor acic suygery.Methods A series of 200patients operated on t he thorax were d ivided into two group s according to the age,an elderly group(above sixty year s old,84cases)and an adult group(below sixty years old,116cases).All cases inspired air before operation and low flow oxygen(2L /min)after operat ion.The arterial blood oxygen had been determined in each case on the pre -ope ration,the first and the third postoperation days respectively.Results Postope rative hypoxemia was8.3%(14/84×2)in the elderly group,and 6.9% (16/116×2)in the adult group.There was only one hypoxemia case occurr ed in the pneumonectomy group.All other 29hypoxemia occurred in t he cases of lobectomy,esophagectom y and other thoracic operations.Conclusions Hypoxemia was not related to age factor,but to the kinds of operation.Slight reduction of lung function does not affect artery blood oxygen.[
