摘要
目的:评价超声诊断急性肺损伤及急性呼吸窘迫综合征(ALI/ARDS)的价值。材料和方法:研究对象为41例呼吸困难的患者,根据动脉血氧分压与吸氧浓度的比值(PaO2/FiO2)分为ALI组(16例)和ARDS组(25例);对照组50例,临床及X线胸片检查正常。用超声按12个肺区扫查肺野。结果:ALI/ARDS患者的胸部超声表现包括彗星尾征、实变及胸腔积液。ALI组,弥漫性彗星尾征或实变范围≤5个肺区者14例(14/16);ARDS组,病变范围≥6个肺区者18例(18/25)。病变范围≥6个肺区,10例生存(10/20);≤5个肺区,19例生存(19/21)。对照组仅在侧胸部最后一个肋间见单发彗星尾征。结论:肺部超声可以观察到ALI/ARDS时肺内病变,并可评估肺损伤的程度及预后。
Purpose： Acute lung injury （ALl） and acute respiratory distress syndrome （ARDS） are a fatal consequence of trauma. The aim of this study was to evaluate ALl and ARDS using ultrasonography. Material and Methods： Forty-one patients with dyspnea were divided into ALl（ n = 16） and ARDS （ n = 25 ） groups according to the ratio of arterial partial pressure to the fraction of inspired oxygen （ PaO2/ FiO2 ）. Their lungs were evaluated by transthoracic sonography over 12 regions on chest wall, and the findings were compared with that of 50 normal controls. Results： Sonographic findings included comet-tail sign, consolidation and pleural effusion involved ≤ 5 regions in 14/16 of ALl, and ≥ 6 regions in 18/25 ARDS. Half of the patients（10/20） with abnormal regions ≥ 6 lung regions survived the trauma, while 19 out of 21 patients with abnormal regions ≤ 5 survived. An isolated comet-tail sign at the last lateral intercostal space was detected in the control group. Conclusion： Ultrasonography was able to observe the pathologic change in lungs therefore of value in the evaluation of lung injury and in the prognosis in patients with ALI/ARDS.
