用重症超声检查诊断低氧血症患者病因的效果研究

Study on the effect of severe ultrasonography in diagnosing the etiology of hypoxemia

目的:探讨用重症超声检查诊断低氧血症患者病因的临床效果。方法:将2018年3月至9月在攀枝花市中心医院进行治疗的98例低氧血症患者作为研究对象。对这些患者进行病史调查及查体、实验室检查、床旁心电图检查、肺部影像学检查等常规检查,诊断其病因。将进行常规检查的结果作为金标准,观察用重症超声检查诊断这些患者病因的情况。结果:用重症超声检查诊断肺实变、胸腔积液、肺水肿、气胸及肺栓塞所致低氧血症的敏感度分别为86.7%、100%、91.7%、84.2%及71.4%。用重症超声检查诊断肺实变、胸腔积液、肺水肿、气胸及肺栓塞所致低氧血症的特异度分别为97.0%、100%、90.5%、97.4%及98.9%。结论:用重症超声检查诊断低氧血症患者病因的敏感度、特异度均较高。

Objective:To explore the clinical effect of severe ultrasonography in diagnosing the etiology of hypoxemia.METHODS:A total of 98 patients with hypoxemia who were treated in Panzhihua Central Hospital from March to September 2018 were included in the study.These patients underwent medical history investigation,physical examination,laboratory examination,bedside electrocardiogram,pulmonary imaging examination and other routine examinations to diagnose the etiology of the disease.The results of routine examinations were used as the gold standard to observe the diagnosis of etiology in these patients by severe ultrasound.Results:The sensitivity of severe ultrasonography in diagnosing pulmonary consolidation,pleural effusion,pulmonary edema,pneumothorax and hypoxemia caused by pulmonary embolism were 86.7%,100%,91.7%,84.2%and 71.4%,respectively.The specificity of severe ultrasonography in the diagnosis of pulmonary consolidation,pleural effusion,pulmonary edema,pneumothorax and hypoxemia caused by pulmonary embolism were 97.0%,100%,90.5%,97.4%and 98.9%,respectively.Conclusion:The diagnosis of the etiology of hypoxemia by sever e ultrasonography has high sensitivity and specificity.
