Objective To explore the clinical effect of lidocaine mucilage diluent and simethicone emulsion in gastroscopy examination, in order to provide effective drugs for gastroscopy. Methods We selected 201 outpatients and the inpatients who underwent gastroscopic examination between August and October 2014 as the research subjects. Based on the kind of drug, the patients were randomly divided into research group (n=100) and control group (n=101). Patients in the research group accepted lidocaine mucilage diluent, while those in the control group received simethicone emulsion. Then we observed and compared the definition of gastroscopy, adverse drug reactions, examination time and drug price between the two groups. Results The frequencies of high, medium, and low definition of gastroscopy were respectively 63.00%, 34.00% and 3.00% among the patients in the research group, and 69.31%, 26.73% and 3.96% among patients in the control group; there was no significant differences between the two groups (Z=-0.854, P=0.393). The adverse reaction rates, testing time, and drug prices for the two groups were 0.99% vs.1.00% (P>0.05), (6.5±2.1) minutes vs.(6.6±2.0) minutes (t=0.458, P>0.05), and RMB (9.0±1.2) yuan vs.(42.8±2.8) yuan (t=227.644, P<0.05), respectively. Conclusion Lidocaine mucilage diluent and simethicone emulsion both have good effect for gastroscopic examination, which can raise the gastroscopic definition, promote endoscopic operation and observation by doctors, shorten examination time, and reduce adverse drug reactions. Both are of great value in clinical application, and lidocaine hydrochloride mucilage diluent is cheaper, which can be widely used and promoted clinically.
