THE NURSE’S PRACTICE IN ORAL HYGIENE FOR PATIENTS WITH OROTRACHEAL TUBE

Abstract

Introduction: Oral hygiene is an essential aspect of nursing care for critically ill patients, especially those using an endotracheal tube (ETT). The presence of this device compromises natural defense mechanisms, such as swallowing and coughing, favoring the colonization of pathogenic microorganisms and the development of ventilator-associated pneumonia (VAP). Objective: To analyze the nurse's practice in oral hygiene for patients using an endotracheal tube, correlating it with institutional protocols and the prevention of respiratory infections. Methodology: This is an integrative review study with a qualitative approach, conducted in the Virtual Health Library (VHL), using the descriptors "nursing care," "oral hygiene," and "mechanical ventilation," combined with the Boolean operator AND. Articles in Portuguese, published between October 2020 and 2025, available in full text, and addressing the role of nurses in oral care were included. Analysis and discussion of results: Studies have revealed that adherence by the nursing team to standardized protocols and investment in continuing education reduce the incidence of VAP. Technical training and the correct use of antiseptic solutions, such as chlorhexidine, are proven strategies for the safety of critically ill patients. Conclusion: The nurse plays a central role in the execution, supervision, and education of the team regarding oral hygiene in intubated patients, ensuring safe, humane, and evidence-based care.
