Abstract:
Objective
To evaluate the differences between the three types of guided endotracheal intubation techniques：traditional laryngoscope，conventional gastroscope and nasal gastroscope.
Methods
The patients with tracheal intubation who underwent general anaesthesia for painless endoscopic surgery at The 960th Hospital of the PLA between January 2024 and December 2024 were enrolled.Patients were randomised into three groups.The conventional laryngoscope group （n=36） was treated with conventional laryngoscope-assisted tracheal intubation，the ordinary gastroscope group （n=45） was treated with ordinary gastroscope-assisted tracheal intubation，and the nasal gastroscope group （n=33） was treated with nasal gastroscope-assisted tracheal intubation.
Results
The success rate of one-time intubation in the conventional gastroscopy group and the nasal gastroscopy group was higher than that in the traditional laryngoscope group （97.8%，100% and 86.1%，χ2 = 5. 426，P=0.046），and the intubation time was There was no significant difference in hemodynamic indexes （HR，MAP，SpO2）among the three groups before anesthesia induction，before tracheal intubation and 5 min after tracheal intubation（P ＞0.05）.In terms of intubation-related complications，there was no significant difference in the incidence of dry mouth，mucosal bleeding，hoarseness，and bloody cuff during extubation among the three groups （P ＞ 0.05）.However，the number of patients with cough and the total number of complications in the traditional laryngoscope group （7 cases，17 cases） were higher than those in the conventional gastroscopy group（3 cases，8 cases） and the nasal gastroscopy group （1 case，4 cases），and the difference was statistically significant（χ2=6.363，P=0.041；χ2=14.267，P＜0.001）.
Conclusion
conventional gastroscopy and nasal gastroscopy improve the success rate of intubation within a certain range，shorten the time of tracheal intubation under general anesthesia，and reduce the complications related to tracheal intubation.It is worth promoting in the endoscopy center.
