Should we proceed with thoracentesis and admission or just medical admission for this patient?

From the Guidelines

I strongly recommend proceeding with both thoracentesis and medical admission for this patient, as the patient's symptoms of shortness of breath (SOB) and inability to lie flat, combined with a history of heart failure (HF) and cirrhosis, suggest a significant pleural effusion that requires both diagnostic and therapeutic intervention. The patient's recent admission with a mixed infection/malignant picture on transudative fluid and current presentation with moderate effusion on chest X-ray (CXR) further support the need for thoracentesis to obtain fluid for analysis and to relieve respiratory distress. According to the EASL clinical practice guidelines for the management of patients with decompensated cirrhosis 1, diagnostic thoracentesis should be performed especially when infection of the pleural effusion is suspected, and therapeutic thoracentesis is indicated in patients with dyspnea. Additionally, the British Thoracic Society guideline for pleural disease 1 recommends image-guided thoracentesis to reduce the risk of complications. Given the patient's complex medical history and current presentation, thoracentesis followed by medical admission is the most appropriate course of action to manage the patient's symptoms, diagnose the underlying cause of the effusion, and guide further treatment. The patient should be admitted for medical management, including appropriate antibiotics if infection is suspected, diuretics like furosemide if heart failure is contributing, and supportive care with oxygen supplementation as needed to maintain saturation above 92%. Serial chest imaging should be performed to assess resolution of the effusion and to determine the need for additional drainage if significant reaccumulation occurs. It is also important to consider the patient's anticoagulation therapy with Apixaban and to monitor for any potential complications related to thoracentesis, such as bleeding or re-expansion pulmonary edema 1.

From the Research

Patient Assessment

• The patient is an 81-year-old male with a history of heart failure (HF) and cirrhosis, presenting with shortness of breath (SOB) and unable to lie flat.
• The patient has no fever and no trauma, and is currently on Apixaban.
• Vital signs: RR 22, SpO2 96% on room air, BP 111/56, with bilateral pitting edema.
• Chest X-ray (CXR) shows moderate effusion.

Treatment Options

• The patient's condition and history suggest the need for thoracentesis to drain the pleural effusion and relieve symptoms.
• Studies have shown that large-volume thoracentesis can be safe and effective in removing pleural fluid, with a low risk of reexpansion pulmonary edema (RPE) 2.
• The use of ultrasound-aided thoracentesis can also improve the safety and feasibility of the procedure, even in mechanically ventilated patients 3.
• Best practice models for thoracentesis emphasize the importance of procedural training, ultrasound imaging, and careful patient selection to reduce the risk of iatrogenic complications 4.

Decision Making

• Given the patient's symptoms and CXR findings, thoracentesis is likely necessary to relieve the pleural effusion and improve the patient's condition.
• The patient's history of HF and cirrhosis, as well as the presence of bilateral pitting edema, suggest that medical admission may also be necessary to manage these underlying conditions.
• However, the decision to drain and admit or just admit medically will depend on the patient's overall clinical status and the results of the thoracentesis procedure.
• It is worth noting that there is no direct evidence in the provided studies to suggest that the patient's specific condition (mixed infection/malignant picture on transudative fluid) would benefit from one approach over the other, but general principles of managing pleural effusions can be applied 5, 6.
