Open-heart surgery patients needing prolonged mechanical ventilation have high mortality. Early tracheostomy may improve outcomes for those who don't wean within a week.

Area of Science:

  • Cardiology
  • Critical Care Medicine
  • Thoracic Surgery

Background:

  • Open-heart surgery patients requiring prolonged mechanical ventilation represent a critically ill subgroup.
  • Understanding their clinical course and the optimal timing for interventions like tracheostomy is crucial for improving outcomes.

Purpose of the Study:

  • To characterize the clinical course of open-heart surgery patients requiring mechanical ventilation for over 72 hours.
  • To define the role and optimal timing of tracheostomy in this patient population.

Main Methods:

  • Retrospective review of 581 open-heart surgery patients over 18 months.
  • Detailed follow-up of 58 patients who required prolonged mechanical ventilation ( > 72 hours).
  • Analysis of intubation, tracheostomy, extubation, and mortality data.

Main Results:

  • Overall mortality for prolonged mechanical ventilation patients was 43%.
  • 55% of survivors were extubated within 14 days; 45% required tracheostomy.
  • Tracheostomy had a lower complication rate (37%) compared to endotracheal tubes (65%).

Conclusions:

  • Patients requiring prolonged mechanical ventilation post-open-heart surgery are a high-risk group.
  • A 1-week trial of weaning is recommended; elective tracheostomy should be considered if weaning fails.
  • Tracheostomy appears to be a safer option with fewer complications in this subset of patients.
