Effect Of Pre-inhaled Salbutamol On Adverse Airway Reactions During Bronchofiberscopic Lavage In Children With Mycoplasma Pneumonia

Objective: To investigate the effect of pre-inhaled salbutamol aerosol on airway adverse reactions during bronchofiberscopic lavage in children with mycoplasma pneumonia.Methods: A total of 100 children with mycoplasma pneumonia in our hospital were performed bronchofiberscopic lavage were selected as research subjects.They were divided into study group and control group according to the random number method,with 50 cases in each group.Children in the study group were given 2 sprays of Salbutamol Sulfate Inhalation Aerosol(approx.200ug)5 minutes before surgery.The control group was not treated.After entering the operating room,all the children were given dexmedetomidine,sufentanil and propofol for rapid intravenous induction,and propofol was continuously pumped intravenously during the operation.Intraoperative vital signs and adverse reactions were observed.Dosage of propofol,sufentanil and dexmedetomidine,intraoperative minimum oxygen saturation,frequency of coughing,and operation suspension,operation time and resuscitation time were recorded.Results: There was no significant difference between the two groups in sex,age and weight(P > 0.05).The median amount of propofol used in the study group was 4mg/kg,lower than 4.26mg/kg in the control group(P<0.05);the percentage of coughing times ≥2 was 18%,lower than 48% in the control group;the percentage of operation suspension times ≥2 was 6%,lower than 20% in the control group,P<0.05;and the difference was statistically significant.The operative time and resuscitation time in the study group were significantly shorter than those in the control group.Conclusion: Pre-inhalation salbutamol aerosol in preoperative can reduce the incidence of coughing during bronchofiberscopic lavage in children with mycoplasma pneumonia,reduce the occurrence of hypoxemia,make the intraoperative vital signs more stable,recover faster after surgery,and make the examination process fluent and safe,which is worthy clinical application.
