Material wear of polymeric tracheostomy tubes: A six-month study,

THE LARYNGOSCOPE, Issue 4 2009
Sara Backman MSc
Abstract Objectives: The objectives were to study long-term material wear of tracheostomy tubes made of silicone (Si), polyvinyl chloride (PVC), and polyurethane (PU) after 3 and 6 months of clinical use. Study Design: The study has a prospective and comparative design. Methods: Nineteen patients with long-term tracheostomy, attending the National Respiratory Center in Sweden, were included, n = 6 with Si tubes, n = 8 with PVC tubes, and n = 5 with PU tubes. The tubes were exposed to the local environment in the trachea for 3 and 6 months and analyzed by scanning electron microscopy, attenuated total reflectance Fourier transform infrared spectroscopy, and differential scanning calorimetry. Results: All tubes revealed severe surface changes. No significant differences were established after 3 or 6 months of exposure between the various materials. The changes had progressed significantly after this period, compared to previously reported changes after 30 days of exposure. The results from all analyzing techniques correlated well. Conclusions: All tubes, exposed in the trachea for 3,6 months, revealed major degradation and changes in the surface of the material. Polymeric tracheostomy tubes should be changed before the end of 3 months of clinical use. Laryngoscope, 2009 [source]


Regular Tracheostomy Tube Changes to Prevent Formation of Granulation Tissue

THE LARYNGOSCOPE, Issue 1 2003
Kathleen Yaremchuk MD
Abstract Objectives/Hypothesis Tracheostomy is a commonly performed operative procedure that has been described since 2000 b.c. The early indications for tracheostomy were for upper airway obstruction, usually occurring in young people as a result of an infectious process. Recently, tracheostomies are more commonly performed in the critically ill patient to assist in long-term ventilatory support. Granulation tissue at the stoma and the trachea has been described as a late complication resulting in bleeding, drainage, and difficulty with maintaining mechanical ventilatory support. Study Design The present report is of an observational study of a newly implemented policy that required regular changing of tracheostomy tubes. Comparable groups of patients were compared before and after this procedural change to document complications. Data collection consisted of chart reviews of all admissions for 1 year before the policy change and the subsequent 2 years. Complication rates were compared using standard statistical techniques. Methods A policy change was instituted that required all tracheostomy tubes to be changed every 2 weeks in conjunction with a detailed evaluation of the tracheostomy stoma. Charts were reviewed the year before the change in policy and in the subsequent 2 years to determine the incidence of granulation tissue requiring operative intervention. Results The number of patients requiring surgical intervention secondary to granulation tissue showed a statistically significant decrease (P = .02). A review of policies and procedures from the six largest hospitals in southeastern Michigan had no recommendations for routine tracheostomy tube changes. Conclusions A policy requiring a routine change of tracheostomy tubes results in fewer complications from granulation tissue. Tracheostomy tube changes to prevent granulation tissue and its complications. [source]


Patient safety incidents associated with airway devices in critical care: a review of reports to the UK National Patient Safety Agency

ANAESTHESIA, Issue 4 2009

Summary We used key words and letter sequences to identify airway-associated patient safety incidents submitted to the UK National Patient Safety Agency from critical care units in England and Wales. We identified 1085 such airway incidents submitted in the two years from October 2005 to September 2007. Three hundred and twelve incidents (28.8%) involved neonates or babies. Of the total 1085 incidents, 200 (18.4%) were associated with tracheal intubation, 53 (4.9%) with tracheostomy and 893 (82.3%) were post-procedure problems. One hundred and ten incidents (10.1%) were associated with more than temporary harm. Eighty-eight intubation incidents were associated with equipment problems. Partial displacement of tubes resulted in more than temporary harm to the patient more frequently than complete tube displacement (15.7% vs 3.8%). Capnography was not described in any cases of displacement or blockage of tracheal or tracheostomy tubes. Recommendations concerning minimum standards for capnography, availability and checking of equipment and tracheostomy placement are made. [source]


Evaluation of a new percutaneous dilatational tracheostomy set

ANAESTHESIA, Issue 9 2001

Percutaneous tracheostomy is a well established technique used primarily to assist weaning from mechanical ventilation on many intensive care units. We report our experiences of a total of 36 procedures performed with the new Blue RhinoÔ Percutaneous Tracheostomy Introducer Set developed by Ciaglia. The technique was successful in all cases and was simpler and quicker to perform than with the earlier Ciaglia percutaneous tracheostomy set. Difficulties were encountered when using ShileyÔ tracheostomy tubes. Significant complications included one posterior wall tear and one tracheal cartilage ring fracture. [source]
