Objective To investigate the effect of bronchoscopy combined with nebulized inhalation of medication on the duration of symptoms and pulmonary imaging conversion in children with Mycoplasma pneumoniae pneumonia(MPP).Methods A total of 94 children with MPP were selected as the research subjects and randomly divided into Group A and Group B using a random number table,with 47 cases in each group.They were treated with budesonide nebulization inhalation therapy and bronchoalveolar lavage combined with budesonide nebulization inhalation therapy,respectively.The duration of symptoms,improvement of lung imaging before and after treatment,levels of inflammatory indicators,and incidence of adverse reactions were compared between the two groups.The results showed that the temperature recovery time was(2.73±0.51)days,cough disappearance time was(5.98±1.24)days,and hospitalization time was(10.96±3.36)days in Group B,(3.14±0.83)days,(7.06±2.33)days,and(13.27±3.18)days in Group A,respectively.Durpation in Group B was shorter than Group A(t=2.885,2.809,3.423,all P<0.05). After treatment,40.43% of the shadows in Group B completely disappeared,34.04% of the shadows significantly reduced,23.40% of the shadows reduced,and 2.13% of the shadows showed no significant improvement,better than 21.28%,36.17%,25.53%,and 17.02% in Group A(Z=8.311,P<0.05). Before treatment,the white blood cell count(WBC),high-sensitivity C-reactive protein(hs CRP),and procalcitonin(PCT)levels in group B were similar to those in Group A(P>0.05).After treatment,the WBC(7.71±1.94)×109 /L,hs CRP(4.96±1.44)mg/L,and PCT(84.32±21.40)pg/mL in Group B were lower than those in Group A(9.05±2.48)×109 /L,(6.17±1.85)mg/L,and(105.46±34.02)pg/mL,respectively(t=2.918,3.538,3.606,all P<0.05).The incidence of adverse reactions in Group B was 8.52%,while in Group A it was 4.26%.The incidence of adverse reactions in group B was similar to that in group A(χ 2 =0.178,P>0.05).Conclusions Bronchoscopy combined with nebulized inhalation therapy for children with MPP can shorten the recovery time,promote the disappearance of lung shadows,reduce their inflammatory index levels,and without increasing the incidence of adverse reactions.
