Analysis of risk factors for planned tracheal extubation failure in patients after posterior fossa surgery

To identify factors influencing planned tracheal extubation failure in patients after posterior fossa surgery. A total of 74 patients admitted to the neurosurgical intensive care unit of a tertiary hospital from January 2022 to January 2024 were recruited via convenience sampling. Clinical data and tracheal extubation-related parameters were collected. High-risk factors for extubation failure were determined through univariate analysis and binary logistic regression. Among the 74 patients, 18 experienced tracheal extubation failure. Significant differences were found in pre-extubation Glasgow Coma Scale (GCS) score, pneumonia, cough strength scores, suction frequency, hypercapnia, and post-extubation swallowing dysfunction (P<0.05). Binary logistic regression identified weak cough strength, hypercapnia, and high suction frequency as risk factors for extubation failure in these patients. Cough strength, Hypercapnia, and suction frequency are key determinants of tracheal extubation outcomes.
