Application effect of homemade visible stomach tube guiding device in patients with gastric canal implantation under general anesthesia

Abstract

Objective To evaluate the application effect of homemade visible stomach tube guiding device in patients with gastric canal implantation under general anesthesia. Methods From January to December 2015, 90 patients who would undergo gastrointestinal or hepatobiliary surgery under general anesthesia with indwelling gastric tube were selected as the research object by purpose sampling method. 90 cases were divided into group A (conventional catheter) , group B (guidewire guided) and group C (homemade visible stomach tube guiding device guided) , with 30 cases in each group. All patients received gastric canal implantation immediately after endotracheal intubation under general anesthesia. We recorded the time of one-time successful gastric tube implantation, the times of implantation, the number of successful cases that implanted at a time, the total number of cases with successful implantation and the number of cases with throat mucosal injury. Results The intubation time of group A and group B were longer than that of group C (P<0.05) . The time in group A was the longest. Only 10 cases in group A were successful implanted in one time, 19 cases in group B were successfully implanted in one time, and all the cases in group C were successfully implanted in one time. The one-time success rate of gastric canal implantation of group C (100.0%) was higher than that of group A (33.3%) and group B (63.3%) (P<0.05) . The total success rate of gastric canal implantation of group A (53.3%) was lower than that of group B (90.0%) and group C (100%) (P<0.05) . The incidence of throat mucosal injury of group C (3.3%) was lower than that of group A (33.3%) and group B (26.7%) (P<0.05) . Conclusions The homemade visible stomach tube guiding device can quickly improve the one-time success rate of gastric canal implantation in patients under general anesthesia, reduce the time of implantation and decrease the incidence of throat mucosal injury.
