Overview

In this study, based on the conceptual framework of Pressure Injurie development, the risk factors for pressure injury in critically ill patients provided by the latest guidelines, and combined with the current relevant studies on mucosal pressure injury, we prospectively observed and collected clinical data related to tracheal intubation patients in the ICU, analyzed the risk factors for the occurrence of oral MPI, and established a risk prediction model to help clinical and nursing staff to detect and actively prevent oral MPI at an early stage The study aims to improve the quality of nursing management, enhance the level of nursing services and improve patient satisfaction.
