目的:探讨呼吸机在连枷胸合并肺挫伤患者治疗中的作用。方法:回顾性分析我院42例连枷胸合并肺挫伤患者,其中16例给予一般治疗,26例加用呼吸机治疗。比较两组患者同一时间点的血气分析结果及治疗效果。结果:两组患者经不同治疗后动脉血氧分压(PO2)均明显升高(P<0.001),统计学结果有显著差异。加用呼吸机治疗组PO2升高更明显(P<0.05),胸壁畸形的发生率(4%)较一般处理组(25%)低。两组在住院时间及肺部感染发生率上无明显差异。结论:呼吸机治疗连枷胸合并肺挫伤的优势在于它可稳定浮动的胸壁,迅速纠正低氧血症,且可防止胸壁畸形的发生。
Objective: To explore the role of ventilator in the treatment of patients with flail chest complicated by pulmonary contusion. Methods: A retrospective analysis of 42 cases of flail chest with pulmonary contusion in our hospital, of which 16 cases were given general treatment, 26 cases were treated with ventilator. The blood gas analysis results and the therapeutic effects at the same time point were compared between the two groups. Results: The arterial partial pressure of oxygen (PO2) in both groups were significantly increased after treatment (P <0.001), and the statistical results were significantly different. Compared with the general treatment group (25%), the PO2 increased more significantly (P <0.05) and the incidence of chest wall deformity (4%) increased with ventilator therapy. There was no significant difference between the two groups in the length of hospital stay and the incidence of pulmonary infection. CONCLUSIONS: The advantage of ventilator in the treatment of flail chest and pulmonary contusion is that it stabilizes the floating thoracic wall, rapidly correct hypoxemia, and prevents the occurrence of chest wall deformity.
