Introduction
As a speech-language pathologist, understanding the complexities of dysphagia in patients with tracheostomies is crucial. The systematic review titled A Systematic Review of Tracheostomy Modifications and Swallowing in Adults by Skoretz et al. (2020) provides valuable insights into how tracheostomy modifications might impact swallowing physiology. With dysphagia affecting 11% to 93% of tracheostomized patients, the need for evidence-based interventions is paramount.
Key Findings from the Systematic Review
The review analyzed 10 studies focusing on tracheostomy modifications and their effects on swallowing. These modifications included:
- Cuff status (inflation vs. deflation)
- Occlusion methods (digital occlusion, one-way speaking valve, total occlusion)
Despite the heterogeneity in study designs and patient populations, some patterns emerged:
- Cuff Deflation: Generally associated with improved swallowing parameters, such as increased anterior hyoid excursion and reduced pharyngeal transit time.
- Speaking Valves: Placement of a speaking valve often reduced aspiration rates, although results varied across studies.
- Occlusion Methods: Mixed results were reported, with some studies indicating reduced aspiration with occlusion.
Implications for Practice
The review underscores the complexity of swallowing physiology in tracheostomized patients and highlights the need for individualized assessment and intervention. Here are some practical takeaways for clinicians:
- Assess Cuff Status: Consider the potential benefits of cuff deflation in improving swallowing outcomes, but weigh this against the patient's respiratory needs.
- Utilize Speaking Valves: Incorporate speaking valves as part of the weaning process to potentially enhance swallowing safety.
- Customize Occlusion Strategies: Tailor occlusion methods based on individual patient needs and responses.
Encouragement for Further Research
While the review provides a comprehensive overview, it also highlights significant gaps in the literature. Future research should aim to:
- Conduct larger, more homogeneous studies to provide clearer evidence.
- Utilize standardized, psychometrically validated tools to assess swallowing outcomes.
- Explore the impact of tracheostomy tube size and type on swallowing physiology.
By advancing research in these areas, we can develop more effective interventions to improve swallowing outcomes in tracheostomized patients.
