The distinction between primary and secondary pneumothoraxes is based on the absence or presence of clinically apparent lung disease.3. Tension pneumothorax is a life threatening complication that requires immediate recognition and urgent treatment.,河北医科大学第四医院胸外科,How is pneumothorax diagnosed?,Symptoms【 chest pain andbreathlessness 】,inspiratory chest radiograph,Computed tomography,pneumothorax,河北医科大学第四医院胸外科,Pathogenesis,1、 Primary Pneumothorax： tobacco smoking；tall men.2、 Secondary spontaneous pneumothorax：COPD； asthma； lung cancer, tuberculosis,,河北医科大学第四医院胸外科,What predicts recurrence of pneumothorax?,Smoking cessation is the only proved modifiable risk factor for recurrence of primary pneumothorax.,Secondary,Rates of recurrence of secondary pneumothorax are noticeably lowered by thoracic surgery.,河北医科大学第四医院胸外科,What are the treatment options?,,Company Logo,Diagram,,Company Logo,Diagram,河北医科大学第四医院胸外科,What advice do patients need after a pneumothorax?,2、Smoking cessation significantly reduces the recurrence rate in patients after an initial primary pneumothorax, with a relative risk reduction of over 40%. Therefore patients should be made aware of this and provided with support to successfully stop smoking,3、scuba diving should be avoided indefinitely after a pneumothorax unless a definitive procedure such as surgical pleurectomy has been performed.4、Air travel should not increase the risk of pneumothorax, but the consequences of a pneumothorax while airborne are such that patients should not travel on commercial flights with an undrained pneumothorax, and air travel should be delayed until after definitive intervention or until resolution has beenconfirmed radiologically.,1、return to work and normal activity after resolution of symptoms, although extreme exertion and contact sports should be delayed for longer and until full radiological resolution,河北医科大学第四医院胸外科,What new treatments can be expected?,1、Quantification of air leakDigital thoracic drainage systems allow a quantification of airleak that is not possible with a conventional underwater seal2、Endobronchial valvesEndobronchial valves have been utilised as a non-surgical meansof achieving a reduction in lung volume in emphysema【肺气肿】 andhave also been studied as a treatment for persistent air leak inpneumothorax3、Blood patchthis technique may be useful as an alternative to chemical pleurodesis inpatients with a significant risk from surgery.4、Ambulatory treatmentHeimlich valves are one-way flutter valves that may be attachedto an intercostal drain in place of an underwater seal。They offeran outpatient treatment option for the management ofpneumothorax, which may have an increasing role in the future,河北医科大学第四医院胸外科,Summary points,1、Primary spontaneous pneumothorax is associated with smoking but defined as occurring in the absence of known lung disease。2、Secondary spontaneous pneumothorax occurs in the presence of known lung disease and is associated with increased symptoms,morbidity, and rates of tension pneumothorax.3、Immediate recognition and management of tension pneumothorax is required to prevent death。4、Smoking increases the risk of pneumothorax and rates of recurrence, and smoking cessation is strongly advised。5、Surgical intervention is warranted for patients with recurrent pneumothorax as the risk of further recurrence is high。,河北医科大学第四医院胸外科,总结,1、无基础肺疾病的原发性自发性气胸往往与吸烟相关。2、继发性自发性气胸与基础肺疾病相关，其症状较多较重，并发症亦较多，易致张力性气胸。3、张力性气胸需要紧急诊断和处理以免死亡。4、吸烟增加气胸的发生及复发风险，故对于气胸患者应推荐戒烟。5、复发性气胸患者再次复发可能性较大，故推荐外科手术治疗,河北医科大学第四医院胸外科,What can we learn from this paper?,1、自发性气胸属于常见病，能够从常见病中总结出来，找出新意，值得我们学习。2、本文每一个小题目都是有根据的，例如【A recent randomised controlled trial of 66 patients with primary or secondary pneumothorax allocated to minithoracotomy or to video assisted thoracic surgery showed equivalent recurrence rates (2.7% and 3%, respectively) and postoperative pain】循证医学体现在每个标题中-这也是这篇文章被BMJ收录的原因3、作为临床医师，经常性阅读本领域的综述性文章对于尽快把握本领域的科研的方向有帮助，同时也要试着去写综述类的文章，尽管Review比不上实验性Article,但是对于锻炼阅读文献、总结、转化临床是有帮助的。,Words and key sentences,河北医科大学第四医院胸外科,1、epidemiology ,epdimld n. 流行病学；传染病学；2、consultation knslte()n n. 咨询；磋商；临床 会诊；讨论会3、admission rates住院率；4、traumatic trmtk; tra- n. 外伤药adj. 外伤的；创伤的5、emphysema ,emfsim n. 临床 气肿；肺气肿6、cardiopulmonary reserve心肺功能储备7、Tension pneumothorax张力性气胸8、visceral pleura脏层胸膜 parietal pleura壁层胸膜9、midclavicular锁骨间的clavicular klvikjul adj. 锁骨的10、hemithorax ,hemi:rks n. 解剖 半胸11、breathlessness brelisnis n. 呼吸急促，气喘吁吁12、tachycardia 英 ,tkkd ,tkkrd 心动过速13、supine s(j)upan adj. 仰卧的；掌心向上的；向后靠 的14、costophrenicadj. 肋膈的(胸膜)15、emphysema ,emfsim n. 临床 气肿；肺气肿16、bullae buli: n. 肺大泡（bulla的复数）；17、parenchyma prekm n. 组织 实质；软细胞组织18、lung apexepeksn. 顶点；尖端19、pulmonary oedema肺水肿20、interstitial lung disease肺间质疾病,sentences,,河北医科大学第四医院,1、It remains a globally important health problem, with considerable associated morbidity and healthcare costs。2、The distinction between primary and secondary pneumothoraxes is based on the absence or presence of clinically apparent lung disease.3、Compared with minithoracotomy, video assisted thoracic surgery was associated with higher patient satisfaction。4、The most important risk factor contributing to risk of primarypneumothorax is tobacco smoking。5、Chronic obstructive pulmonary disease is the most commonlung disease causing secondary pneumothorax, acc
