ABSTRACT
Objective To study the clinical efficacy of using bronchoalveolar lavage in severe lobar pneumonia and to analyze the high-risk factors affecting the duration of the disease.Methods The clinical data of children with severe lobar pneumonia diagnosed in the Department of Pediatrics,the First Affiliated Hospital of Shihezi University from January 2018 to January 2022 were retrospectively collected,and the children in the lavage group and the control group were matched 11 according to whether bronchoalveolar lavage was performed using the propensityscore matching(PSM)method to compare the therapeutic effects of the two groups.At the same time,the children in the lavage group were divided into the long-duration group and the short-duration group according to whether the duration of the disease was more than 2 weeks,and the reasons for the difference in the duration of the disease between the two groups were analyzed.Results ① After treatment,the children in the lavage group had cough relief time,fever reduction time,lung rales disappearance time,lung imaging manifestations reduction time,white blood cell(WBC),neutrophil to lymphocyte ratio neutrophil-to-lymphocyte ratio(NLR),C-reactive protein(CRP),erythrocytes sedimentation rate(ESR),and procalcitonin(PCT)were all lower than those in the control group,and the differences were statistically significant(P<0.05).② In the lavage group,the CRP,lactate dehydrogenase(LDH),and fever peak value of children in the long-course group were significantly higher;The proportions of multi-pulmonary lobe infection,combined pleural effusion,and multiple pathogen infections were significantly higher than those in the short-course group.The difference was statistically significant among disease course groups(P<0.05).③ Two-category Logistic and receiver operating characteristic curve(ROC curve)analysis showed that LDH and CRP were independent risk factors for the disease duration in children in the lavage group>2 weeks,and the optimal critical values of LDH and CRP for predicting a disease duration of>2 weeks in children with severe lobar pneumonia were 333U/L and 32.6mg/L,respectively.Conclusion ① Bronchoalveolar lavage can shorten the treatment time of children with lobar pneumonia,speed up the recovery of inflammation,and significantly improve the efficacy.② Multiple pathogenic mixed infections,concurrent pleural effusion,LDH≥333 U/L,and CRP≥32.6 mg/L are independent risk factors for the disease duration>2 weeks after alveolar lavage in children with lobar pneumonia.We need to be alert to the possibility of prolonged disease course.
