Fine needle aspiration; with imaging guidance
Thoracentesis requires several key instruments, including a sterile needle or catheter, a syringe for fluid aspiration, and a collection container for the pleural fluid. Additionally, a local anesthetic may be used to numb the insertion site, and ultrasound guidance is often employed to enhance safety and accuracy. Sterile gloves and antiseptic solutions are also essential for maintaining a sterile environment during the procedure.
