RESUMO
Objective To observe and compare the incidence of cough among patients with post-infection cough undergoing painless gastroscopy.Methods Seventy-one patients with post-infection cough undergoing painless gastroscopy were enrolled and randomly divided into two groups.The observation group (34 cases) received budesonide nebulization before gastroscopy and the control group (37 cases) was performed gastroscopy directly.We observed the incidence of cough at different time point and the changes of circulationduring the operation. Results The incidence of cough between the observation group and the control group showed statistically significant differences (P＜0.01) . The changes of circulation showed statistical differences between two groups in the process of gastroscopy (P＜0.05).Conclusion Budesonide nebulization supplying can decrease the incidence of post-in-fection cough among patients undergoing painless gastroscopy.
