肺部超声评分联合CRP/SDI、PCT/SDI在预测重症细菌性肺炎患者短期预后中的价值分析
Analysis of the value of lung ultrasound score combined with CRP/SDI and PCT/SDI in predicting short-term prognosis of patients with severe bacterial pneumonia
摘要
Abstract
Objective:To investigate the value of lung ultrasound(LUS)score combined with C-reactive protein(CRP)/simp-son's diversity index(SDI)and procalcitoninogen(PCT)/SDI in predicting the short-term prognosis of patients with severe bacte-rial pneumonia(BP).Methods:A total of 198 cases of BP patients attending the Neijiang Second People's Hospital from De-cember 2020 to December 2024 were selected,and the patients were divided into the critically ill group(124 cases)and the non-critically ill group(74 cases)according to the degree of their critical condition,and the death caused by BP was used as the endpoint event,and they were classified into the group of bad prognosis(57 cases)and the group of good prognosis(141 cases)according to the prognosis of the patients at 28 days after the onset of the disease.The score of LUS,CRP/SDI and PCT/SDI were compared between two groups,and the factors influencing the short-term poor prognosis of patients with severe BP were analyzed by univariate and COX regression,and the bad prognosis group was defined as positive and the good prog-nosis group was defined as negative,and the ROC of the subjects was plotted,the AUC was obtained,the value of the score of LUS combined with CRP/SDI and PCT/SDI in predicting short-term prognosis of patients with severe BP was analyzed.Results:Compared with the non-critical group,the APACHE Ⅱ,LUS score and CRP/SDI,PCT/SDI were higher in the criti-cal group(P＜0.05).Compared with the good prognosis group,the LUS score and CRP/SDI and PCT/SDI were higher in the bad prognosis group(P＜0.05).The results of COX analyses showed that score of LUS and CRP/SDI,PCT/SDI were the risk factors for short-term poor prognosis of patients with severe BP(HR=3.077,1.968,1.669,P＜0.05).ROC analysis showed that the AUC value of LUS score combined with CRP/SDI and PCT/SDI for predicting short-term poor prognosis in patients with severe BP was 0.942,which was higher than that of each index detected separately(0.835,0.814,0.816,P＜0.05).Conclusion:APACHEⅡ,LUS score and CRP/SDI,PCT/SDI were higher in patients with severe BP,LUS score and CRP/SDI,PCT/SDI were asso-ciated with poor short-term prognosis of patients,and the predictive value of the above indicators was higher in the short-term prognosis of patients with severe BP.关键词
