Background: Preterm infants usually have multiple complications, mainly due to their low birth weight. Multiple factors may lead to the need for intubating preterm infants. However, some infants may suffer from difficult extubation and failure to extubate from ventilation. This failure can result in increased morbidity or mortality. Objective: This study aims to evaluate the factors contributing to the failure of extubation and their outcomes in preterm infants. Materials and Methods: This is a retrospective descriptive cohort study that included records from neonatal intensive care unit for patients who had failed extubation from January 2014 to December 2020. The data included information about patients' demographics, pregnancy and delivery, description of ventilation course, and outcomes. SPSS version 26 was used for statistical analysis. Results: Seventy-seven infants were included. Males represented 61%, birth weight 37.7% had a <1 kg, 45.5% of the patients had a gestational age <28 weeks. The mean duration for mechanical ventilation was 19.21 ± 3.2 days, while the duration of intubation was 26.53 ± 2.3 days, and the average length of hospital stay was 86.2 ± 6.7 days. Male gender (P = 0.023), birth weight less than one kilogram (P = 0.004), gestational age <28 weeks (P = 0.033), sedation (P = 0.043), caffeine administration (P = 0.048), and a previous history of extubation failure (P = 0.036), lower hemoglobin levels (P = 0.039), lower APGAR score at 5 min (P = 0.013), and a previous history of extubation failure (P = 0.036) were significant factors associated with failure of extubation. Patent ductus arteriosus presence is not associated with failure of extubation. Mortality was 24.7% and prolonged length of hospital stay was significantly higher in babies with failure of extubation. Conclusion: Failure of extubation is more with babies received sedation, male gender, birth weight <1 kg, lower gestation age, and lower Apgar at 5 min. Patients with failing extubation have high in-hospital mortality and prolonged hospital stay.
