What are common complications in elderly patients undergoing thoracentesis?

• A. Pneumothorax, edema, and dehydration
• B. Pleural effusion, atelectasis, and sepsis
• C. Pneumonia, liver failure, and arrhythmia
• D. Migraine, anemia, and dermatitis

Answer: (D)

The key idea is recognizing which complications commonly follow thoracentesis, and how age can influence those risks. The most familiar and frequent issue after inserting the needle into the pleural space is pneumothorax, which happens when air leaks into the space around the lung due to a puncture or misplacement. Elderly patients often have reduced lung resilience and may have underlying lung disease like emphysema, increasing the chance that a puncture will lead to a pneumothorax and make management more challenging. Bleeding is another important risk, particularly in older adults who may have coexisting anticoagulation therapy, platelet disorders, or fragile intercostal vessels. Infection at the entry site or within the pleural space is a possible complication but occurs less commonly than pneumothorax or bleeding. Reexpansion pulmonary edema can occur if a large volume is removed quickly, especially in patients with already compromised lung function. Thus, when thinking about thoracentesis complications in the elderly, pneumothorax sits at the forefront as the main concern, with bleeding, infection, and reexpansion edema as additional important possibilities. The other nonspecific symptoms listed in the choices, such as migraines, dermatitis, or unrelated organ failures, do not reflect typical immediate complications of this procedure.
