January to October 2018 were selected by convenience sampling method. The clinical data and the occurrence of unplanned extubation were retrospectively collected. The influencing factors of unplanned extubation were analyzed by univariate analysis and binary unconditional Logistic regression analysis. Results? Among 1 682 patients with indwelling nasobiliary tube, 44 patients had unplanned extubation during hospitalization, the incidence was 2.62%. Logistic regression analysis showed that age, sex, education level, sensory disturbance and indwelling time were the influencing factors of unplanned extubation. Conclusions? The unplanned extubation in patients with indwelling nasobiliary tube is the result of multiple factors. Comprehensive and effective measures should be taken to prevent unplanned extubation in clinical nursing.

Objective:To explore the clinical application values of modified esophagus metal stent auxiliary line device in improving the comfort level of patients.Methods:By the convenient sampling method, a total of 16 patients with tracheoesophageal fistula who were admitted and treated in Hangzhou First People's Hospital Affiliated to Zhejiang University School of Medicine from March 2014 to September 2016 were selected as the control group. After the implantation of the esophageal stent with an auxiliary line, an ulcer patch was used to protect the skin behind the ears and cheeks, and there was no protection for the nasal cavity and throat mucosa. A total of 19 patients with tracheoesophageal fistula who were admitted from October 2016 to November 2019 were selected as the experimental group. On the basis of using ulcer patch to protect the skin, the auxiliary line of the stent was passed through the infusion hose. The infusion hose entered the nasal cavity along the auxiliary line and reached the front of the stent through the throat. The comfort degree and the incidence of nasal ulcer were compared between the two groups.Results:The self-perceived comfort level of patients on 10 days after implantation of the esophageal stent with an auxiliary line in the experimental group was (4.16±0.83) and that on 20 days after implantation was (6.05±0.97) , both of which were superior to the control group, and the differences were statistically significant ( t=-8.340, -7.030; P < 0.01) . At 30 days after surgery, the incidence of nasal ulcers in the experimental group was 47.37% and that in the control group was 100.0%. The difference between the two groups was statistically significant ( P<0.01) . Conclusions:The modified esophageal metal stent auxiliary line device can improve comfort level of patients and reduce the incidence of nasal ulcers, which has certain clinical application value.
