Chest tube insertion should be well-rehearsed and instinctive. You should not hesitate to insert a life-saving tube into a pleural cavity immediately to drain air, blood, bile, or pus. Obtaining a thorough history and chest x-ray is absolutely pivotal to your diagnosis. Know your landmarks before insertion: the fourth and fifth intercostal space and the anterior-axial line. Go up and over the rib as you insert chest tubes. Avoid the lower rib margin to prevent injury to the neurovascular bundle.
You can use one of several tube thoracostomy techniques. Most clinicians prefer standard or classic insertion, that is, blunt dissection (incision, Kelly clamp, finger placement, tube placement).…

Full disclosure, these are tips and tricks I learned by trial and error and through word of mouth, and they have not been formally studied or peer reviewed.
Bougie-assisted intercostal catheter insertion
Bougies can be used as a rescue technique for intercostal catheter insertion when the standard approach is problematic (e.g. in an obese patient where it is easy to lose the tract when inserting the intercostal catheter)
Chest drains & aspiration: Do it better with St.Emlyn’s
This is just a quickie to support some local teaching in Virchester on ‘chest drain’ insertion, or ‘intercostal drains’ if you prefer additional consonants or ‘chest tubes’ if you are from the land of the Trump. Anyway chest drains are one of those procedures that are rare enough that we need to think about, but common enough that we really should be expert in.

Small-bore chest tubes seem to perform better than larger tubes in treatment of spontaneous pneumothorax
Compared with patients treated with smaller chest tubes, patients with surgical large-bore tubes had more complications (27.4% versus 9.5%; p = 0.026), a lower success rate (56.5% versus 85.7%; p = 0.002), and longer duration of chest tube (8.3 versus 4.9 days; p = 0.001) and of hospitalisation (11.8 versus 6.9 days; p = 0.004).
Unlocking Common ED Procedures – Cutting Through the Triangle: A Review of Tube Thoracostomy in the ED
Placement of a thoracostomy tube, more frequently referred to as a chest tube in the ED, is one of the most common invasive surgical procedures performed by emergency physicians. While this classic procedure has undergone several stages of evolution over the years, its principle is still centered around the placement of a tube or catheter within the pleural cavity with the intent of draining either air or fluid that has collected within the intrapleural space.
What’s the Best Intervention for Primary Spontaneous Pneumothorax?
The management of an otherwise stable but symptomatic patient with PSP typically boils down to a few key decisions. First, is any intervention required? Secondly, if so, what sort of invention: standard chest tube, narrow-bore chest tube, or aspiration? Finally, should a patient be discharged home or remain in the hospital for observation?
