肺部超声监测B线数目与CT对新冠肺炎康复患者的评估价值

Value of lung ultrasound B-lines in evaluation of convalescent COVID-19 pneumonia with comparison to CT

目的:观察肺部超声监测B线数目与CT评估新冠病毒肺炎(COVID-19)康复期患者的价值。方法:回顾性分析2020年1-3月广州市第八人民医院收治的87例COVID-19患者的临床资料,收集患者入院、出院及随访时的肺部超声、CT资料,并分析其对康复期患者的病情评估价值。结果:肺部超声与CT诊断肺实变一致性较好(Kappa=0.788,P<0.05);两组出院时和随访时肺部超声、CT征象均提示病情减轻;与入院时相比较,出院、随访时肺部超声B线数、肺间质综合征、肺实变、胸膜下病变均减少,且随访时肺部超声指标较出院时明显改善(P<0.05)。结论:新冠肺炎康复期患者肺部超声监测显示B线数目较入院时明显减少,且在对肺水肿的检测上敏感度优于CT检查,可对病情进行有效监测和评估。

Objective:To determine the value of B-lines in lung ultrasound monitoring and CT for evaluating convalescent patients with COVID-19.Methods:The clinical data of 87 COVID-19 patients admitted to the Guangzhou Eighth People’s Hospital between January and March of 2020 were reviewed.Data on lung ultrasound and CT scan at admission/discharge and during follow-up were retrieved to evaluate their role in evaluating the condition of these patients during convalescence.Results:Lung ultrasonography was well consistent with CT in identification of lung consolidation(Kappa=0.788,P<0.05).Signs of either lung ultrasonography or CT at discharge and during follow-up showed resolution of the patient condition.Compared with findings at admission,the number of ultrasound B-lines,interstitial lung syndrome,lung consolidation,and subpleural lesions were all reduced at discharge and during follow-up;lung ultrasonographic fundings was significantly even more improved during follow-up compared with those at discharge(P<0.05).Conclusion:Significantly fewer lung ultrasound B-lines are found in patients with COVID-19 pneumonia during convalescence compared with at admission.Using lung ultrasound B-lines can be more sensitive in detecting pulmonary edema than with CT,which enables effective monitoring and evaluation of patient condition.
