Evidence-Based Nursing Practice About Impaired Ventilatory Weaning - Systematized Literature Review

Giselda Pacheco Silva, Isabel Cruz

Abstract


Mechanical ventilation is necessary to reverse respiratory disorders and has the negative effect of physical deconditioning as a result of the need for sedation and restriction of movement. Weaning is considered difficult when the patient meets the criteria to leave ventilatory support and has one or more failures in attempts at extubation, or when, after starting weaning, it is impossible to complete the withdrawal process. Objective: to show what specialized literature is about nursing interventions with patients weaning from mechanical ventilation. Methods: it is an integrative literature review with the following question: What is the specialized literature about nursing interventions with patients weaning from mechanical ventilation? Results: 10 full articles were used found in the database of Latin American and Caribbean Literature in Health Sciences (LILACS), Medical Literature Analysis and Retrieval System Online (MEDLINE) and the EMBASE biomedical database, based on the time frame between the years 2012 to 2019 with articles in the Portuguese language. Discussion: ventilatory weaning is defined as the abrupt or gradual withdrawal of ventilatory support and contributes at least 40% of the overall MV period. Even so, several factors contribute to the failure of weaning and return to MV, such as retention of secretions, atelectasis, pulmonary congestion, myocardial ischemia, laryngeal edema and bronchoaspiration. Conclusion: Throughout the research, there was a shortage regarding the care of nursing professionals with patients on Mechanical Ventilation with indication for Ventilatory Weaning, since what is in vogue is only to identify care in certain groups.
