Objective:To explore the preventive measures of nasal pressure injury in patients with preserved nasal endotracheal intubation after oral and maxillofacial neoplasms resection and simultaneous free tissue flap transplantation.Methods:Using the convenient sampling method, a total of 520 patients who underwent oral and maxillofacial neoplasms resection and simultaneous free tissue flap transplantation in Peking University Hospital of Stomatology were selected as the research objects from August 2018 to December 2019. According to the random number table method, they were divided into the experimental group and the control group. Patients in the control group received routine care, while in the experimental group, silk surgical tape was used to re-fix the endotracheal intubation tube away from the original position, and the special-shaped inflatable balloon was used to support the remote end of the tube. The incidence of nasal pressure injury, medical adhesive-related skin injury (MARSI) and the occurrence of complications caused by the fixation of tracheal intubation of patients were compared between the two groups. In the end, 246 patients in the experimental group and 248 patients in the control group completed the study.Results:No stage 3 or above nasal pressure injury occurred in the two groups. The incidence of nasal pressure injury related to nasotracheal tube in the experimental group was 2.85% (7/246) , lower than 12.10% (30/248) in the control group (χ 2=15.254, P<0.001) . There was no statistically significant difference in the incidence of MARSI of patients between the two groups ( P>0.05) . No complications caused by endotracheal intubation fixation occurred in both groups. Conclusions:The use of silk surgical tape to re-fix the endotracheal intubation and the combination of special inflatable balloon to support the end of the endotracheal intubation can prevent nasal pressure injury, and the safety is better.
