Objective To observe the clinical efficacy and safety of Azithromycin Sequential Therapy in the treatment of mycoplasma pneumonia for children.Methods 112 children with mycoplasma pneumonia were randomly divided into observation group and control group,each 56 cases.The observation group was treated with Azithromycin Sequential Therapy in the treatment,while the control group was treated with erythromycin lactobionate anti infection treatment.The clinical efficacy was compared between two groups after treatment,the clinical symptoms disappeared time and drug adverse reaction occurred the situation.Results The total effective rate of the observation group was 96.43%,which was significantly higher than 80.36% of the control group,the difference was statistically significant (χ2 =7.04,P <0.05).The fever,cough,pulmonary rales disappearance time of the observation group were (3.74 ± 1.58)d,(3.24 ±0.47)d,(5.58 ±2.23)d,which were significantly shorter than (4.68 ±1.71 )d,(4.64 ± 0.97)d,(7.82 ±2.70)d of the control group(t =4.27,4.68,4.59,all P <0.05).The gastrointestinal reactions, local pain,rash,the elevation of ALT of the observation group were significantly lower than the control group,the difference was statistically significant (χ2 =4.26,7.04,7.03,5.23,all P <0.05 ).Conclusion Azithromycin Sequential Therapy for the treatment of mycoplasma pneumonia in children has the advantages of good clinical effica-cy,fast effect,high safety.
