A 58-year-old woman undergoes elective tracheostomy for laryngeal papillomatosis requiring repeated laser ablations. During the procedure, the surgeon notes significant bleeding from the operative site. Which of the following is NOT a recognized early (within 24 hours) complication of tracheostomy?

## Early vs. Late Complications of Tracheostomy ### Early Complications (Within 24 Hours to 1 Week) **Key Point:** Early complications are typically **mechanical or hemorrhagic** and occur immediately or within days: | Complication | Timing | Mechanism | |---|---|---| | **Hemorrhage** | Immediate–24 hrs | Vessel erosion, inadequate hemostasis | | **Tube obstruction** | Immediate–48 hrs | Blood clot, thick secretions, tube malposition | | **Subcutaneous emphysema** | Immediate–24 hrs | Air leak from tracheal defect or tube cuff | | **Accidental decannulation** | 24 hrs–7 days | Tube dislodgement, inadequate fixation | | **Tube malposition** | Immediate–48 hrs | Intratracheal placement, posterior wall perforation | | **Tracheal stenosis** | **Weeks to months** | Cuff pressure, mucosal ischemia, fibrosis | ### Why Option 3 (Tracheal Stenosis) Is NOT an Early Complication **High-Yield:** Tracheal stenosis is a **late complication** (weeks to months, even years) caused by: - Chronic cuff pressure → mucosal ischemia - Granulation tissue formation - Fibrosis and scar contracture It **cannot** develop within 24 hours; it requires time for tissue remodeling and fibrosis. ### Early Complications in This Vignette **Clinical Pearl:** In a patient with significant intraoperative bleeding: - **Hemorrhage** (option 0) is the immediate risk - **Tube obstruction** (option 1) can occur if blood clots the lumen - **Subcutaneous emphysema** (option 2) may develop if there is air leak around the tube or from the tracheal defect All three are recognized within 24 hours; stenosis is not. **Mnemonic:** **HASTE** for early tracheostomy complications: - **H**emorrhage - **A**ccidental decannulation - **S**ubcutaneous emphysema - **T**ube obstruction - **E**dema (laryngeal, from tube irritation) **Tip:** Stenosis is a **late complication**; if the question asks "early complications," stenosis is always the wrong answer.
