Analysis of Factors and Clinical Outcomes of Planned Tracheal Extubation Failure in Neurosurgical Intensive Care Unit Patients

BACKGROUND: Planned tracheal extubation failure is a common occurrence among patients in the neurosurgical intensive care unit (NICU) because of the complex nature of neurocritical injuries, and the failure could result in a poor prognosis. METHODS: We observed and recorded the patients with tracheal intubation in the NICU of a hospital in Shanghai from June 2021 to December 2022 and analyzed data from planned tracheal extubation, categorizing patients by success or failure, and compared outcomes between the two groups while investigating contributing factors. RESULTS: A total of 156 patients were included, 133 (85.3%) of whom were successfully extubated and 23 (14.7%) were not. The results of logistic regression analysis demonstrated that the Glasgow Coma Scale score before extubation (OR, 0.643; 95% CI, 0.444-0.931; P = .020) and the frequency of respiratory secretions suctioning before tracheal extubation (OR, 0.098; 95% CI, 0.027-0.354; P < .001) were independent risk factors for extubation failure. We also found that the extubation failure group experienced a significantly longer ICU stay and incurred higher hospitalization costs. CONCLUSIONS: Poor Glasgow Coma Scale scores and a high frequency of respiratory secretions suctioning before tracheal extubation were the main factors contributing to tracheal extubation failure in NICU patients. To avoid tracheal extubation failure and adverse outcomes, these two factors should be carefully assessed before tracheal extubation.
