One hundred seventy-one patients admitted to a Medical ICU and who received treatment for respiratory failure with mechanical ventilation were studied for the development of pulmonary barotrauma (PBT) as manifested by pneumomediastinum, subcutaneous emphysema, or pneumothorax. Fourteen patients (8%; group A) developed this complication; they were younger, had higher maximal peak inspiratory airway pressures (PIP); and higher levels of maximal PEEP. We conclude that for medical patients treated for respiratory failure with mechanical ventilation, the incidence of PBT is 8% and that younger age, higher levels of PIP and PEEP seem to pose an increased risk for developing PBT.
对171名入住内科重症监护病房（Medical ICU）并接受机械通气治疗呼吸衰竭的患者进行了研究，以观察肺气压伤（PBT）的发生情况，其表现为纵隔气肿、皮下气肿或气胸。14名患者（8%；A组）出现了这种并发症；他们更年轻，吸气气道峰压（PIP）最大值更高，呼气末正压（PEEP）最大值水平也更高。我们得出结论，对于接受机械通气治疗呼吸衰竭的内科患者，PBT的发生率为8%，而且年龄较小、PIP和PEEP水平较高似乎会增加发生PBT的风险。
