Comparison of Talc Slurry Versus Talc Insufflation: A Study on Effectiveness, Safety, and Hospital Outcomes in Pleurodesis

Pleural effusion is characterized by the accumulation of fluid in the pleural space, which typically contains about 10-20 mL of pleural fluid that is crucial for the movement of the lungs against the chest wall. This fluid closely resembles plasma but has a lower protein concentration, usually less than 1.5 gm/dL. It primarily originates from pleural capillaries and the interstitial spaces of the lung, and is reabsorbed through the lymphatic vessels in the parietal pleura, either via small openings known as stomas or through a process called transcytosis (1, 2). When the balance between fluid production and reabsorption is disrupted-often due to various pathogenic mechanisms-it can lead to pleural effusion. In such cases, effective management is essential. This study aims to conduct a thorough comparison of the two talc administration methods-TS and TI-using sterilized, large-particle, asbestos-free talc powder. By examining key outcome measures such as pleurodesis success rates, procedural morbidity, and length of hospital stay, the goal is to provide clinicians with evidence-based guidance to facilitate informed decision-making in the management of pleural effusions.
