From the Guidelines
For patients with tracheostomies, secretion suction frequency should decrease to 1-2 times per day or less before attempting capping trials, as this indicates the patient's ability to manage secretions independently and reduces the risk of airway obstruction during capping.
Key Considerations
- Patients should demonstrate the ability to clear secretions independently through coughing and swallowing before capping is considered safe 1.
- Begin capping trials when the patient has stable respiratory status, oxygen saturation above 92% on room air or baseline oxygen, minimal secretions, and effective cough.
- Start with short periods (5-15 minutes) and gradually increase duration as tolerated, monitoring for signs of respiratory distress, increased work of breathing, or oxygen desaturation.
- During trials, have suction equipment readily available, and consider the use of inner tubes to reduce the risk of tube occlusion with secretions 1.
- If the patient tolerates capping for 24-48 hours without complications, they may be ready for decannulation assessment.
Secretion Management and Capping
The relationship between secretion management and capping is critical because excessive secretions during capping can lead to airway obstruction, as the capped tracheostomy prevents expectoration through the tube 1.
- Successful capping requires adequate upper airway patency and effective secretion management, which is why reduced suction frequency serves as an important clinical indicator of readiness for this progression in tracheostomy weaning.
- Passing a suction catheter via the tracheostomy can establish whether or not the airway is patent along its length and also allow therapeutic suction to be performed 1.
From the Research
Relationship Between Secretion Suction Frequency and Tracheostomy Capping Trials
- The relationship between secretion suction frequency and tracheostomy capping trials is not directly addressed in the provided studies 2, 3, 4, 5, 6.
- However, studies suggest that secretion management is a crucial aspect of tracheostomy care, and suctioning is a common technique used to remove secretions from the airway 5.
- The frequency of suctioning may be influenced by the patient's condition, the type of tracheostomy tube, and the presence of any complications such as bleeding or tracheal stenosis 2.
- Tracheostomy capping trials are a method used to assess a patient's readiness for decannulation, and the ability to manage secretions is an important factor in this assessment 3, 6.
- A study by 6 found that the ability to generate peak cough flows (PCF) greater than 160 L/min was a predictor of successful extubation and decannulation, suggesting that effective secretion management is critical for successful tracheostomy tube removal.
- Another study by 4 found that patients who underwent tracheostomy for secretion management had different outcomes compared to those who underwent tracheostomy for prolonged ventilation, highlighting the importance of considering the indication for tracheostomy when evaluating secretion management strategies.
- Overall, while the exact relationship between secretion suction frequency and tracheostomy capping trials is not clearly defined, effective secretion management is a critical aspect of tracheostomy care, and suctioning frequency may be influenced by a variety of factors, including the patient's condition and the presence of any complications 2, 3, 4, 5, 6.
