Objective To investigate the safety and feasibility of dyclonine combined with propofol in the application of painless gastroscopy. Methods A total of 90 patients received the painless gastroscopy in our hospi-tal were enrolled from September to December 2016. They were divided into 3 groups according to the random number table(n=30):Dyclonine+propofol(DP)group,Fentanyl+propofol(FP)group,Propofol(P)group. The hemodynamic changes,adverse reaction,propofol dosage,time of gastroscopy examination and time of conscious recovery were observed and recorded. Results Compared with P group,the incidence of hypertension,tachycardia, choking cough,body movement and the dosage of propofol in DP group and FP group were significantly decreased (P<0.05,respectively). Compared with DP group,the incidence of respiratory depression,the time of gastroscopy examination and the time of Conscious recovery in FP group and P group were significantly increased (P < 0.01 , respectively). Compared with FP group,the incidence of nausea and vomiting in DP and P group were significantly decreased (P < 0.05 ,respectively). Conclusions Dyclonine combined with propofol reduced the incidence of cardiovascular response,choking cough,body movement,respiratory depression,and nausea and vomiting,with the reduced dosage of propofol ,the shorten gastroscopy examination time and the recovery time. Therefore ,dyclo-nine combined with propofol is a safe and feasible anaesthesia management for the painless gastroscopy.
