Analysis on two methods of indwelling gastric tube

Abstract

Objective To explore the application value of lidocaine hydrochloride gel in the nursing of indwelling gastric tube by clinical study of two methods of indwelling gastric tube. Methods A total of 160 cases of patients with gastric tube indwelling admitted to this hospital from January 2016 to January 2017 in the experimental group were selected.They were randomly divided into the experimental group and the control group, 80 cases of each group.The control group was given gastric tube indwelling by routine method.In the experimental group, the gastric tube was lubricated with a mixture of lidocaine hydrochloride and paraffin oil and combined with oral lidocaine hydrochloride.The blood pressure, heart rate, primary success rate, duration, discomfort and tolerance of patients in the two groups before and after gastric catheterization were observed and compared. Results Nasopharyngeal pain, nausea, tears, aised blood pressure, elevated heart rate, vomiting, coughing, mucosal hemorrhage and other discomfort symptoms were significantly lower than those in the control group(P<0.01). The success rate of primary catheterization of the experimental group was higher than that of the control group(P<0.05). The mean blood pressure and heart rate of the experimental group were significantly lower than those of the control group, and the time of indwelling gastric tube was shorter than that of the control group(P<0.01). The tolerance level 0 and level Ⅰ of the experimental group were significantly higher than those of the control group(P<0.01), level Ⅱ was significantly lower than the control group(P<0.01), and level Ⅲ was significantly lower than the control group(P<0.05). Conclusions The application of lidocaine hydrochloride gel before gastric catheter indwelling reduces the adverse reactions of patients, improves the comfort level of patients, relieves the tension of patients, shortens the time of indwelling gastric catheter, and improves the success rate of primary catheterization.It is safe and feasible.
