Objective To study the effect of double lumen bronchial tube on the success rate of resuscitation in the patients with respiratory and cardiac arrest caused by the injury.Methods 44 cases of prehospital respiratory and cardiac arrest caused by chest trauma (one-sided pneumothorax, pneumothorax) from February 2004 to February 2010 of our hospital were randomly selected as the control group. Resuscitation method: took the basic life support and gave the chest closed drainage, after the end of the tracheal intubation, and then performed cardiopulmonary resuscitation for 30 min, quickly transferred the patients with respiratory and heart recovery to the hospital for comprehensive treatment, and tracked the success rate of recovery. 44 cases of prehospital respiratory and cardiac arrest caused by chest trauma from March 2010 to March 2015 of our hospital were selected as the experiment group. Resuscitation method: took basic life support and double lumen bronchial intubation(10 s) at the same time, single-lung ventilation for injured pulmonary sequestration, and then performed cardiopulmonary resuscitation for 30 min, the patients with the recovery of respiratory and heart rate immediately underwent thoracic close drainage and double-lung ventilation, quickly transferred to the hospital for comprehensive treatment, and track the success rate of recovery.Results In control group, 20 patients were successfully resuscitated, 24 patients died, the recovery success rate was 45.45%(20/44), patients were given comprehensive treatment after successful cardiopulmonary resuscitation, and 5 patients were discharged, the hospital survival rate was 25%(5/20). In experimental group, 31 patients were successfully resuscitated, the recovery success rate was 70.45%(31/44), patients were given comprehensive treatment after successful cardiopulmonary resuscitation, and 10 patients were discharged, the hospital survival rate was 45.16%(14/31). The difference of success rate of cardiopulmonary resuscitation between two groups is statistically significant (χ2=5.64,P<0.05). The difference of discharge survival rate between two groups was statistically significant (χ2=3.48,P<0.05).Conclusions The basic life support and establishment of advanced airway by the double lumen bronchus for the patients with respiratory and cardiac arrest caused by chest trauma, can improve the success rate of cardiopulmonary resuscitation and discharge rate.%目的：研究双腔支气管导管对院前胸部损伤（单侧气胸、血气胸）所致呼吸心跳骤停患者复苏成功率的影响。方法随机选取江油市骨科医院2004-02至2010-02院前胸部损伤致呼吸心跳骤停44例为对照组，复苏方法：采取基础生命支持同时给予胸腔闭式引流，完毕后行气管插管，再复苏30 min，呼吸心跳恢复者，迅速转入医院进行综合治疗，并追踪患者康复出院率；选取2010-03至2015-03院前胸部损伤致呼吸心跳骤停44例为实验组，复苏方法：采取基础生命支持同时双腔支气管插管（10 s内完成）将伤肺隔离行单肺通气，再复苏30 min，呼吸心跳恢复者，立即伤侧胸腔闭式引流行双肺通气，迅速转入医院进行综合治疗，并追踪患者康复出院率。结果对照组20例复苏成功，24例抢救无效死亡，复苏成功率45.45%（20/44），复苏成功者经后续综合治疗，5人康复出院，出院生存率为25.00%（5/20）；实验组31例复苏成功，复苏成功率70.45%（31/44），复苏成功者经后续综合治疗，14人康复出院，出院生存率为45.16%（14/31）。两组心肺复苏成功率比较，差异有统计学意义（χ2=5.64，P<0.05）；两组出院生存率比较，差异有统计学意义（χ2=3.48，P<0.05）。结论对胸部创伤所致呼吸心跳骤停患者采取基础生命支持同时给予双腔支气管建立高级气道，可提高复苏成功率和出院生存率。
