## Early Complications of Tracheostomy **Key Point:** Early complications occur within the first week and are usually mechanical or infectious in nature. ### Timing and Frequency of Complications | Complication | Timing | Incidence | Severity | |---|---|---|---| | **Tube obstruction** | 0–48 hrs | Most common early | Minor–moderate | | **Bleeding** | 0–7 days | Common | Minor–moderate | | **Subcutaneous emphysema** | 0–7 days | Common | Minor | | **Tracheal stenosis** | Weeks–months | Late | Severe | | **Tracheo-innominate fistula** | 3–6 days (rare) | <1% | Life-threatening | | **Persistent fistula** | Months after decannulation | Late | Minor | ### Why Tube Obstruction Is Most Common Early 1. **Immediate post-operative state:** Bleeding into the trachea and secretion accumulation occur immediately after tube placement. 2. **Inadequate humidification:** Dry inspired air causes mucus crusting and tube blockage. 3. **Reversible and preventable:** Regular suctioning and humidification reduce incidence significantly. **Clinical Pearl:** Tube obstruction presents with sudden dyspnea, stridor, or inability to pass a suction catheter. Management is immediate tube removal and replacement. **High-Yield:** Tracheo-innominate fistula, though rare (0.5–1%), is the most **life-threatening** early complication and occurs 3–6 days post-op due to tube erosion into the artery at the level of the cuff.
