Abstract：Objective To explore the application value of gastroscope-guided tracheal intubation in the diagnosis and treatment of digestive endoscopy.Methods A prospective selection of 140 patients undergoing gastrointestinal endo-scopic diagnosis and treatment with planned endotracheal intubation was conducted.These patients were divided into the observation group(n=70)and control group(n=70)using a random number table method.The experimental group under-went gastroscope-guided tracheal intubation,while the control group underwent video laryngoscope-guided intubation.The intubation time,first tracheal intubation success rate,hemodynamic indicators[heart rate(HR)and mean arterial pres-sure(MAP)],and incidence of complications were recorded and statistically analyzed.Results The success rate of first endotracheal intubation in the observation group was higher than that in the control group,but the difference was not statis-tically significant(P>0.05).Compared with the control group,the intubation time in the observation group was shorter,and both HR and MAP were lower immediately after intubation(T1)and 1 minute after intubation(T2)(both P<0.05).Compared with the control group,the incidence of choking cough and mucosal injury in the observation group was signifi-cantly lower(both P<0.05).Gastroscopy guidance was a protective factor for intubation complications(OR=0.642,P=0.008),while intubation time was an independent risk factor(OR=2.051,P=0.001).Conclusion Gastroscope-guid-ed tracheal intubation offers advantages such as shorter operation time,more stable hemodynamics,and fewer complica-tions,making it suitable for patients requiring combined diagnostic and therapeutic digestive endoscopy.
