方法：回溯性研究，收集台灣南部某教學醫院於加護病房使用機械通氣經專責醫師評估病況穩定且執行計劃性拔管後120 小時未再插管之臨床病資。以SPSS 18.0 進行統計分析，定義統計顯著為p < 0.05。
結論：多因素logistic regression model 分析顯示：插管天數長、呼吸衰竭種類為肺部呼吸道系統及因換氣不足插管者，延遲脫離的勝算高。
Objectives: Prolonged weaning affects mortality and the extubation success rate during hospitalization. The aim of the present study was to discuss the factors impacting prolonged weaning of respiratory failure patients. The research results are expected to help medical care teams understand and improve the incidence of prolonged weaning.
Methods: This was a retrospective study. The medical records data were collected from a regional teaching hospital in southern Taiwan. The patients were admitted to the intensive care unit, intubated, and mechanical ventilation was initiated. When a patient was stable based on attending physician assessment, planned extubation was performed for at least 120 h without re-intubation. Statistical analyses were conducted on the data using SPSS 18.0. The level of signifi cance was set at 0.05.
Results: The cumulative incidences of the simple, difficult, and prolonged weaning groups were 49.4%, 33.7%, and 16.9%, respectively. A higher proportion of patients with prolonged weaning were intubated for pneumonia and pulmonary respiratory failure types.
Conclusions: Based on a multivariate logistic regression model analysis, intubation days, pulmonary respiratory failure types, and intubation due to hyperventilation had a greater odds of prolonged weaning.|
