Summary

Bacteraemia is a frequent complication after percutaneous tracheostomy. Bloodstream infections often involve bacteria from the patient's own trachea or skin, highlighting the need for vigilance.

Area of Science:

  • Infectious Diseases
  • Critical Care Medicine
  • Surgical Complications

Background:

  • Percutaneous tracheostomy is a common procedure in intensive care settings.
  • Understanding post-procedural infectious complications is crucial for patient safety.

Purpose of the Study:

  • To determine the incidence of bacteraemia (bloodstream infection) following percutaneous tracheostomy.
  • To identify the common causative organisms and their sources.

Main Methods:

  • Prospective study of 106 consecutive bedside percutaneous tracheostomies.
  • Comparison of post-tracheostomy blood cultures with other blood cultures from the same patients.
  • Analysis of organism sources (skin, trachea) and impact of antibiotic use.

Main Results:

  • The incidence of positive post-tracheostomy blood cultures was 10.4%, higher than other blood cultures (6.6%).
  • Staphylococcus epidermidis was the most frequent organism.
  • Organisms in positive cultures often matched those found in the patient's tracheal secretions.

Conclusions:

  • Bacteraemia is a significant complication of percutaneous tracheostomy.
  • The primary sources of infection are the patient's trachea and skin flora.
  • Antibiotic use at the time of tracheostomy did not significantly alter the bacteraemia incidence.
