Interventions
Intrapleural administration of TolueneSulfonamide
PTS Administration (One Treatment Cycle): One treatment cycle is defined as one week. PTS is administered three times per week on Days 1, 3, and 5. Prior to each administration, pleural effusion is drained as completely as possible until no further fluid can be obtained. The study drug is then administered via the indwelling drainage catheter, followed by an additional flush of 20 mL of normal saline. The drainage catheter is clamped for at least 24 hours after administration. After each injection, patients are instructed to maintain prone, lateral, and supine positions for approximately 30 minutes each to facilitate even distribution of the drug within the pleural cavity. During the same treatment cycle, the drainage catheter remains clamped until the next scheduled administration. After completion of treatment, catheter drainage and standard care are continued.
Intrapleural administration of normal saline injection
