To explore the preservation effect of aerosol inhalation of short-acting bronchodilators on pulmonary function in patients undergoing bronchoscopy.

A total of 36 patients who were scheduled to undergo bronchoscopy in our hospital from February 2019 to April 2019 were involved and randomly divided into control group or observation group. Patients in the control group received aerosol inhalation of tetracaine through compressed air atomizer before operation as in the observation group short-acting bronchodilator therapy was combined with tetracaine. The vital signs, oxygen saturation and pulmonary function index before and after bronchoscopy were compared between the two groups.

There was no significant difference in vital signs, oxygen saturation and ventilatory function between the two groups before operation. As the systolic blood pressure, oxygen saturation and ventilatory function changed significantly after bronchoscopy in both groups, short-acting bronchodilator aerosol inhalation significantly improved the ventilation function and oxygen saturation and stabilized heart rate in the observational group than the control group.

Bronchoscopy performance is able to impair ventilatory function while aerosol inhalation of short-acting bronchodilator before bronchoscopy can effectively preserve the pulmonary function and improve perioperative safety.
