One of the most impoant complication of tracheostomy is: September 2008
**Core Concept**
Tracheostomy is a surgical procedure that creates an airway through an incision in the anterior neck, allowing for a tube to be inserted into the trachea. One of the major complications of tracheostomy is related to the anatomy of the trachea and the surrounding structures.
**Why the Correct Answer is Right**
The most important complication of tracheostomy is **pneumothorax**. This occurs when the needle or tube inadvertently punctures the pleura, leading to air entering the thoracic cavity and causing the lung to collapse. This is often due to the proximity of the trachea to the pleura in the neck. The risk of pneumothorax is higher in patients with underlying lung disease or those who require a tracheostomy in an emergency setting.
**Why Each Wrong Option is Incorrect**
* **Option A:** Tracheal stenosis is a possible complication of tracheostomy, but it is not the most common or immediate complication.
* **Option B:** Wound infection is a potential complication of tracheostomy, but it is not as life-threatening as pneumothorax.
* **Option C:** Hemorrhage is a possible complication of tracheostomy, but it is not as common as pneumothorax.
**Clinical Pearl / High-Yield Fact**
When performing a tracheostomy, it is essential to take care not to puncture the pleura, as this can lead to pneumothorax. The trachea and pleura are closely related in the neck, and the risk of pneumothorax is higher in patients with underlying lung disease.
**Correct Answer: A. Pneumothorax**
