El lugar de elección es el espacio comprendido entre el 7 y 8 espacio intercostal. En caso de sospechar la presencia de derrame (que se puede confirmar por la presencia de una ''linea de matidez'' a la percusión), deberemos de insertar la aguja en el tercio más ventral del tórax. En caso de sospechar de neumotórax (sonido hipersonoro a la percusión), la aguja se insertará en el tercio más dorsal. Puede ser necesario en empleo de anestesis local.

Tras rasurar y desinfectar la zona de trabajo (siempre bilateral) se introduce la aguja lentamente con un angulo de 45 grados, haciéndola avanzar hacia el espacio pleural.

The site for thoracocentesis is between the '''7th and 8th intercostal space'''. If fluid is suspected in the pleural space then the needle should be inserted '''2/3rds of the way down the chest'''. If '''pneumothorax''' is suspected then the needle should be inserted more '''dorsally''', approximately '''1/3rd of the way down the chest'''. Local anaesthetic can be used if necessary.
      
Clip and scrub a generous area around the '''7-8th rib space''' on both sides of the chest. Advance the needle slowly at a '''45 degree angle''' in the middle of the 7th or 8th intercostal space into the pleural space. A small amount of '''negative pressure''' should be applied as the needle passes through the thoracic wall. The needle should be angled downward, '''parallel to the body wall'''. The fluid or air should then be aspirated. The needle may need redirecting to access pockets of fluid.
