气管切开术在肺部爆震伤救治中的意义

The role of tracheotomy in saving the patients suffered from lung blast injury

目的 :探讨气管切开术在肺部爆震伤救治过程中的意义。方法 :对 8例肺爆震伤患者的临床资料作回顾性分析。结果 :3例严重的肺部爆震伤患者有 度呼吸困难 ,Sa O2 <75 % ,立即行气管切开术 ,吸出气管内的血性泡沫痰 ,均获救。而另 5例患者 Sa O2 ≥ 90 % ,行保守治疗痊愈。结论 :肺部爆震伤后 ,有 度以上的呼吸困难 ,Sa O2 <75 %时 ,应行气管切开术 ,以便吸出气管内的血性泡沫痰 ,保持气道通畅。

Objective:To explore the role of tracheotomy in saving the patients suffered from lung blast injury.Method:To analyse the pathological change of lung blast injury and to make a retrospective analysis for clinical data of 8 cases.Result:Three severe injuries accompanying asphyxia, SaO 2<75%,were tracheotomized and sucked hemorrhagic forthy sputum in trachea at once, and they were saved successfully.The other 5 cases, SaO 2≥90%,were not tracheotomized.Conclusion:During saving the lung blast injury,tracheotomy has an importmant role in sucking hemorrhagic forthy sputum in trachea and keeping the respiratory tract unobstructed.
