Which nerve can be damaged during lung decortication affecting diaphragm function?

• A. Phrenic
• B. Hypoglossal
• C. Accessory
• D. Vagus

Answer: (A)

The phrenic nerve is responsible for providing motor innervation to the diaphragm, the primary muscle involved in respiration. During lung decortication, which is a surgical procedure to remove fibrous tissue from the surface of the lung, the phrenic nerve is at risk of being injured due to its anatomical proximity to the lungs and mediastinum. Damage to this nerve can result in impaired diaphragm function, leading to respiratory difficulties since the diaphragm plays a crucial role in inhalation. Understanding the role of the phrenic nerve emphasizes the significance of its preservation during thoracic surgeries to maintain effective respiratory mechanics. The other nerves listed do not have a direct association with diaphragm function; thus, they are not relevant in the context of lung decortication and its potential impact on breathing.
