Needle thoracocentesis is normally first attempted in the second intercostal space in the midclavicular line, directing the needle directly above the rib to avoid the intercostal vessels and nerve.

Here are the steps:

1. Position the patient upright, leaning forward slightly if possible.
2. Identify the second intercostal space in the midclavicular line. This is usually in line with the fourth rib because the first rib is often hidden under the clavicle.
3. Clean the area with antiseptic solution and apply sterile drapes.
4. Inject local anesthetic into the skin and deeper tissues.
5. Insert the needle or catheter directly above the top edge of the third rib (to avoid the intercostal vessels and nerve that run along the bottom edge of each rib) at a 90-degree angle to the chest wall.
6. Aspirate as you advance the needle. You should feel a give as the needle enters the pleural space and you should then be able to aspirate air or fluid.
7. Once you have aspirated air or fluid, stop advancing the needle and stabilize it in place.
8. Connect the needle to a three-way tap and syringe or underwater seal.
9. Aspirate until no more air or fluid can be removed or the patient feels uncomfortable.
10. Remove the needle and cover the site with a sterile dressing.
