There are few studies using animal models in chest physical therapy. However, there are no models to assess these effects in newborns. This study aimed to develop a model of obstructive atelectasis induced by artificial mucus injection in the lungs of newborn piglets, for the study of neonatal physiotherapy. ⋯ Our model of atelectasis in newborn piglets is both feasible and appropriate to evaluate the impact of physical therapies on atelectasis in newborns.

Prolonged chest tube duration is less well studied in patients who are supported by mechanical ventilation and have acquired pneumothorax. We investigated the impact of prolonged chest tube duration on patient outcomes and the risk factors associated with prolonged chest tube duration. ⋯ High peak inspiratory pressure and surgical emphysema are independent predictors of prolonged chest tube duration and negatively impact clinical outcomes in this patient group. These findings may provide information for better chest tube management.
