Which symptom is NOT typically associated with pneumothorax in neonates?

High fevers are not typically associated with pneumothorax in neonates. Pneumothorax refers to the presence of air in the pleural space, which can occur after trauma, during mechanical ventilation, or spontaneously, and it primarily affects respiratory function rather than causing systemic symptoms such as fever.

In cases of pneumothorax, signs and symptoms are usually related to respiratory distress and changes in lung mechanics. Increased irritability, decreased breath sounds on the affected side, and an asymmetric appearance of the chest are all consistent with the condition due to the impact on lung expansion and oxygenation. For example, as air accumulates in the pleural space, it can lead to decreased lung volume on the affected side, which is mirrored in the clinical presentation. Therefore, recognizing the symptoms associated with pneumothorax is essential for timely diagnosis and management.
