新型一次性气管插管固定器在无痛胃镜中的临床应用效果OACSTPCD

Objective To study the clinical application of a new disposable tracheal intubation fixator in patients with painless gastroscopy.Methods Patients were divided into two groups according to the fixator used in painless gastroscopy.The control group used traditional plastic bite,and the observation group used a new disposable tracheal intubation fixator(gastroscope protector).Use propensity score matching to eliminate the influence of two groups of potential confounding factors,so that the two groups were comparable,and then analyze the relevant factors affecting adverse reactions.Furthermore,the percutaneous arterial oxygen saturation(SpO2),the success rate of one-time intubation,the time of entering the lens,the stability of the catheterization,the convenience of sputum suction and oxygen supply of medical staff were compared between the two groups.Results After 1∶1 matching,124 patients were included in the control group and the observation group.There was no statistically significant difference in general information between the two groups(P＞0.05),indicating that the variables were balanced and well matched.The results showed that the incidence of agitation,bite prolapse,gastroscope bite and sore throat in the observation group was significantly lower than that in the control group(P＜0.05).Further analysis showed that there was no significant difference in SpO2 and heart rate(HR)between the two groups before examination.During the examination,HR of the control group was significantly faster than that before the examination,and SpO2 was significantly lower than that before the examination,the differences were statistically significant(P＜0.05).There was no significant change in the observation group.The stability after intubation fixation and the success rate of one-time intubation in the observation group were significantly higher than those in the control group,and the entry time was significantly shorter than that in the control group,with statistically significant differences(P＜0.05).In addition,the convenience of sputum suction and oxygen supply in the observation group was higher.Univariate and multivariate Logistic regression analysis showed that age＞70 years old,BMI≥24 kg/m2 and not using the new disposable tracheal intubation fixator were independent risk factors for adverse reactions during painless gastroscopy.Conclusion The new disposable tracheal intubation fixator for painless gastroscopy patients has high safety and convenience of operation,which is worthy of clinical promotion.
