What can happen with the recesses of the body and how can we diagnose and treat these conditions?
Recesses - These are the spaces where blood, pus, or pleural effusions can collect or pool. When this happens, SOB can result. You need to do a CT or US and then tap the fluid out, called Thoracentesis.
What causes a pneumothorax after a penetrating wound? What other conditions do we see with this and what tool do we use to stop the immediate danger?
Each breath generates negative and positive pressures. If the air and waterproof seal of the pleural space is broken, via a penetration wound for example, air follows the path of least resistance and is drawn into the the chest wound rather than through the normal air passages. The air entering the from the wound collapses the lung (called Pneumothorax) and if followed by a collection of blood, a hemothorax. The air also makes a whooshing sound as it enters the wound (sucking chest wound).
Treatment: Chest tube. If you place it on the negative pressure, the lungs will re-expand and the blood will drain. Insert in intercostal space.
