After a right lower lobectomy, constant bubbling in the water-seal chamber of a chest tube drainage system typically indicates a potential air leak, which is a significant concern in postoperative care. Checking for subcutaneous emphysema is critical because it can signify air leaking into the subcutaneous tissue, often a result of a rupture in the pleura or other surgical complications. Observing for subcutaneous emphysema helps determine the extent of the air leak and guides further management.

Identifying subcutaneous emphysema can aid in assessing the severity of the situation, allowing for a more informed response regarding the patient’s care and potentially necessitating intervention, such as adjusting the tube or notifying the healthcare provider for further evaluation. This proactive approach can help prevent complications such as tension pneumothorax, which can arise from untreated air leaks.

While other actions, like repositioning the client or monitoring the drainage output, have their importance in patient care, they do not address the immediate concern of a potential air leak indicated by the bubbling in the water-seal chamber. The priority is ensuring the patient’s safety and addressing any complications from the surgery.
