Abstract:
Objective To investigate the correlation between lung Point-of-Care ultrasound score and clinical indicators by analyzing the features of Point-of-Care ultrasound in acute COVID-19.Methods 30 COVID-19 patients admitted to the Affili-ated Hospital of North Sichuan Medical College were selected,lung Point-of-Care ultrasound sequential scan was conducted in pa-tients with the BLUE-PLUS regimen and the lung Point-of-Care ultrasound semi-quantitative scoring was performed.The clinical indicators of partial pressure of carbon dioxide,anion gap,PH value,standard bicarbonate,oxygen partial pressure,oxygen satu-ration,the lymphocyte percentage(LYM% ),the lymphocytic absolute value(LYM#),the clinical typing,hospital stay,etc were collected.The lung Point-of-Care ultrasound score of acute COVID-19 patients in different clinical typing was compared and the features of Point-of-Care ultrasound in acute COVID-19 were analyzed.The ROC curve was constructed to analyze the effec-tiveness of lung Point-of-Care ultrasound score for the typing of normal type and(critical)severe type.Results In 30 cases of COVID-19 patients during the acute period,there were 29 patients with at least one lung point involvement on both sides(96.7% ),1 case with at least one lung point involvement on one side(3.3% )and 15 cases showed Lung consolidation＞1cm at least one lung point.Comparison of the same lung point between the left and right lung was performed and there was statistical-ly significant difference in the total scores between the left and right lung(P＜0.05).Comparison of total scores of different lung points in patients with different clinical types showed there was statistically significant difference in the total scores of left lung,the total scores of right lung,the total scores of whole lung between normal type and critical type(P＜0.05).The area under the curve(AUC)for the diagnosis of normal and(critical)severe types based on the total lung scores is 0.870.The total scores of the left lung,right lung,and whole lung were not correlated with LYM% ,LYM#,and anion gap(P＞0.05)were positively cor-related with clinical typing and hospital stay,and negatively correlated with standard bicarbonate(P＜0.05).The total scores of the left lung and whole lung were negatively correlated with PH value,oxygen partial pressure,and oxygen saturation,but posi-tively correlated with partial pressure of carbon dioxide(P＜0.05).The total scores of the right lung was not correlated with PH value,partial pressure of carbon dioxide,oxygen partial pressure,and oxygen saturation(P＞0.05).Conclusion There were differences in Point-of-Care ultrasound features among patients with different clinical types of acute COVID-19,Lung Point-of-Care ultrasound semi-quantitative scoring is correlated with pH value,partial pressure of carbon dioxide,standard bicarbonate,ox-ygen partial pressure,oxygen saturation,clinical typing and hospital stay.The patients of critical type have higher scores,lung Point-of-Care ultrasound is expected to be used for clinical typing and condition evaluation of acute COVID-19 patients.
