[Evidence-based practice of self-made tracheal catheter fixation band in prevention of unplanned extubation].

With the development of medical technology, the fixation method of the oral duct is constantly updated, and the selection of a relatively safe, effective, simple and fast fixation method of the oral duct has been widely concerned. However, the use of traditional 3M I-shaped tape fixation needs to be cut, which wastes time and easily leads to the outward displacement of the tracheal tube, and is easy to be soaked by oral secretions, resulting in facial skin damage. Therefore, the medical staffs of the department of critical care medicine of Hengshui People's Hospital designed a self-made tracheal catheter fixing band (composed of the main structure, the fixed band, the internal adjusting structure and the internal structure of the fixed block), and obtained the national utility model patent (ZL 2018 2 0508681.6). The inner side of the fixing band is fixed with a spongy body, which can absorb the secretions around the mouth to avoid the moist condition around the mouth and cheek skin. Meanwhile, the endotracheal catheter is fixed with the help of the card slot, hinge and other structures, which can fully ensure the fixation effect. A total of 80 patients undergoing airway intubation were admitted to the department of critical care medicine of our hospital from October 2020 to September 2021. They were divided into observation group and control group according to intubation time (single number and double number), with 40 patients in each group. The observation group was fixed with self-made tracheal catheter fixation band. Through evidence-based practice path, relevant literatures at home and abroad were searched for clinical practice basis, and the practice plan was formulated and implemented. The control group was fixed with 3M tape + inch tape according to the traditional method. The fixation of tracheal tube and the degree of facial skin injury were compared between the two groups. All patients were included in the final analysis without shedding cases. Severe catheter displacement occurred in 3 patients (7.5%) in the control group, and no severe catheter displacement occurred in the observation group. The incidence of facial skin injury in the observation group was significantly lower than that in the control group [25.0% (10/40) vs. 55.0% (22/40), P < 0.05]. Moreover, the fixation time of the observation group was significantly shorter than that of the control group (minute: 12.11±1.69 vs 17.59±1.27, P < 0.05). The application of self-made tracheal catheter fixation band can shorten the fixation time of tracheal catheter and reduce the incidence of unplanned endotracheal extubation (UEE) and facial skin injury, which is worthy of clinical promotion and application.
