Objective:To investigate the advantages of the modified external fixation of urinary catheters over routine fixation

and to find a better method that can enhance catheter stability and improve nursing efficiency for clinical promotion. Methods:We enrolled 180 eligible patients who were hospitalized from January 1 to June 30

2018 in the Department of Urology

Department of Orthopedics

and Department of Neurology in the Affiliated Hospital of Southwest Medical University. They were randomly divided into routine group（n = 60）

spiral fixation group（n = 60）

and Ⅰ-type fixation group（n = 60）. The days of effective catheter fixation

the number of cases with unplanned extubation（UEX）

and the number of cases with medical adhesive-related skin injuries（MARSI）were compared between the three groups. Results:Compared with the routine group

the spiral fixation group and the Ⅰ-type fixation group had significantly fewer cases with UEX（P < 0.05）. The Ⅰ-type fixation group showed significantly more days of effective catheter fixation than the spiral fixation group and the routine group（P < 0.05）. Conclusion:Both the spiral fixation and Ⅰ-type fixation methods are superior to the routine method in terms of reducing the incidence of UEX in patients with urinary catheterization. The Ⅰ-type fixation method shows an advantage in the days of effective catheter securement over the other two methods. The Ⅰ-type fixation method enhances catheter stability

decreases the incidence of UEX

and reduces nurse providers’ workload

worthy of clinical promotion.
