A critical event in tracheostomy care

L Clarke

    British Journal of Nursing (Mark Allen Publishing)
    |June 12, 1995
    PubMed
    Summary

    Endotracheal suctioning requires careful indication. Saline instillation offers no benefit, while heat and moisture exchangers effectively humidify artificial airways, and tracheostomy tube changes need further research.

    Area of Science:

    • Critical Care Medicine
    • Respiratory Therapy

    Background:

    • Endotracheal suctioning is a common but potentially hazardous procedure in critical care.
    • Maintaining airway patency and adequate humidification are crucial for patients with artificial airways.

    Observation:

    • Saline instillation prior to endotracheal suctioning appears to provide minimal to no clinical value.
    • Heat and moisture exchangers (HMEs) are effective in providing humidification for patients requiring artificial airways.
    • Tracheostomy tube management, specifically the optimal timing for tube changes, requires further investigation.
    • Tracheostomy tube blockages are identified as a preventable complication.

    Findings:

    • The routine use of saline before endotracheal suctioning is not supported by evidence.
    • Heat and moisture exchangers ensure adequate airway humidification.
    • Optimal protocols for tracheostomy tube changes are not yet established.
    • Preventable factors contribute to tracheostomy tube blockages.

    Implications:

    • Clinical practice guidelines for endotracheal suctioning should be updated to reflect the lack of benefit from saline instillation.
    • Heat and moisture exchangers represent a valuable tool for airway management.
    • Further research is needed to establish evidence-based guidelines for tracheostomy tube changes.
    • Implementing preventative strategies can reduce the incidence of tracheostomy tube blockages.
