First Local Anaesthesia Thoracoscopy for Pleural Effusion Diagnosis.

"The patient is placed in a lateral decubitus, with the affected hemithorax upwards. Ensuring a venous line and full monitoring of vital functions. Mild sedation is given and a dose of Ceftriaxone is given 30 minutes before. Local anesthesia is injected in layers, starting from the skin and working up to the intercostal muscles, intercostal nerve, and periosteum of the rib.~Development of pneumothorax is done using a 16-gauge Boutin needle. 15 spontaneous breaths are sufficient to create a pneumothorax, and entry of rigid thoracoscope into the hemithorax through a 11-13 mm Trocar. Multiple biopsies from the parietal pleura are taken and pleurodesis is made according to operator judgment. A chest drain 20-22 G is placed and sutured.~A chest X-ray is performed 2-8 hours later after the patient is transferred to the ward. Chest drain is removed after 24h if fluid production is \<250ml and lung re-expansion."

A video thoracoscope with an external light source, outer diameter 10 mm (Karl Storz), is inserted into the pleural cavity through a uniportal incision (1 - 1.5 cm) and complete inspection of the pleural cavity is performed. Parietal pleural biopsies are taken with a rigid 40 mm forceps (Karl Storz).
