Factors Associated with Intubation in Patients with Central Airway Obstruction Caused by Tumors: A Single-Center, Retrospective Cohort Study
Keywords:
Central airway obstruction, intubation, tumors, retrospective study, predictorsAbstract
Background: This single-center retrospective cohort study aimed to identify factors associated with intubation among patients with central airway obstruction (CAO) caused by tumors in the Lung Center of the Philippines.
Objectives: The primary aim is to identify the key variables contributing to the need for intubation in this patient population, thereby enhancing clinical understanding and potentially improving airway management strategies for individuals with CAO caused by tumors.
Methods: Data from patients admitted to the Lung Center of the Philippines from 2015 to 2023 and with a diagnosis of neck, lung, or intrathoracic tumors causing central airway obstruction (CAO) were retrospectively analyzed. Potential factors including age, sex, type, degree, location, degree, and type of obstruction, tissue diagnosis, and treatment received were assessed.
Results: Of 178 CAO patients, 37.08% required intubation during their hospital stay. Delayed intubation (88%) and an armored endotracheal tube (53%) were utilized in intubating these patients. Labored breathing (74%) and desaturation (73%) were prevalent symptoms. Univariable analysis revealed that the type of obstruction was significantly associated with intubation, with extraluminal obstruction and mixed obstruction, showing increased odds (OR 2.07 and OR 7.02, respectively) compared to endoluminal obstruction.
Conclusion: This study revealed labored breathing and desaturation as the most common symptoms in intubated CAO subjects. Univariable analysis showed that the type of obstruction was significantly associated with the need for intubation. Compared to those with endoluminal obstruction, patients with extraluminal obstruction had two times higher odds of intubation. In contrast, those with mixed obstruction had seven times higher odds. Multivariable analysis showed that the type of obstruction was the only statistically significant variable associated with the need for intubation.
