目的探讨创伤后出现连枷胸,严重肺损伤及中等量以上血气胸,心脏大血管损伤,合并食管、膈肌破裂,并发ARDS的呼吸机治疗原则。方法早期应用呼吸机辅助通气,模式为IPPV或SIMV加PEEP,并记录分析疗效。结果治愈38例,治愈率92.7%,死亡3例,病死率7.3%。结论早期应用呼吸机治疗严重胸部创伤是降低本病病死率的有效措施。 Objective To investigate the treatment principle of ventilator with traumatic flail chest, severe lung injury and moderate amount of pneumothorax, cardiac major vessel injury, combined esophageal and diaphragmatic rupture and ARDS. Methods Ventilator assisted ventilation was used in the early stage. The mode was IPPV or SIMV plus PEEP, and the curative effect was recorded and analyzed. Results cured 38 cases, the cure rate was 92.7%, 3 died, the fatality rate of 7.3%. Conclusion Early use of ventilator in the treatment of severe chest trauma is an effective measure to reduce the mortality of this disease.
