本文对14例创伤性浮动胸壁诊治进行分析,认为浮动胸壁本身对机体的生理破坏并不严重,浮动胸壁造成的反常呼吸出现的缺氧主要是由肺挫伤引起。反常呼吸的强弱主要取决于肺挫伤的程度,肺挫伤越重,反常呼吸运动的幅度就越大,同时并发呼吸窘迫综合征(ARDS)机会就越多。因此,对浮动胸壁的处理重点应放在治疗肺挫伤和ARDS上,并根据动脉O_2分压、CO_2分压、pH值、潮气量及肺活量的水平来决定是否使用机械通气。机械通气仍然是治疗严重肺挫伤、防治ARDS的有效措施。
In this paper, 14 cases of traumatic floating chest wall analysis of treatment, that the floating chest wall itself is not serious physiological damage to the body, floating chest wall abnormal breathing caused by hypoxia is mainly caused by pulmonary contusion. The intensity of abnormal breathing depends largely on the degree of pulmonary contusion. The more severe the lung contusion, the greater the magnitude of abnormal respiratory activity and the greater the chance of concurrent respiratory distress syndrome (ARDS). Therefore, the treatment of floating chest wall should focus on the treatment of pulmonary contusion and ARDS, and according to arterial O_2 partial pressure, CO_2 partial pressure, pH, tidal volume and vital capacity level to decide whether to use mechanical ventilation. Mechanical ventilation is still an effective measure to treat severe pulmonary contusion and prevent and treat ARDS.
