title: Cricoid palpability as a selection criterion for bedside tracheostomy.
abstract: OBJECTIVE
  To prospectively evaluate the significance of cricoid cartilage palpability as a selection criterion for bedside tracheostomy and to prospectively compare a cohort of patients undergoing bedside tracheostomy with another cohort receiving operating room tracheostomy.
  
  
  METHODS
  Prospective trial comparing 2 cohorts of patients receiving tracheostomies at a tertiary care center (university hospital). In all, 220 consecutive intubated patients selected for elective tracheostomy were enrolled. Of them, 134 patients had palpable cricoid cartilage and underwent open surgical tracheostomy at the bedside. The remaining 68 patients received open surgical tracheostomies in the operating room. Demographic data, patient anatomic features, and perioperative complications were prospectively recorded. There were no statistically significant differences in age, gender, reason for admission, indication for tracheostomy, Acute Physiology and Chronic Health Evaluation II score, number of days intubated, or time required to perform the procedure for those patients whose tracheostomies were performed in the operating room versus the intensive care unit.
  
  
  RESULTS
  Patients with a palpable cricoid cartilage had a significantly reduced perioperative complication rate compared with those without a palpable cricoid cartilage (2% vs 22%, P < 0.001). Comparison of cervical girth, mental-to-sternum distance, and thyroid-notch-to-sternum distance showed no significant difference between the 2 groups and did not further define selection criteria.
  
  
  CONCLUSIONS
  This investigation prospectively confirms the safety of bedside tracheostomy placement in properly selected patients. Complication incidences are defined for open surgical tracheostomy at the bedside and in the operating room. Palpability of the cricoid cartilage has significant value as a selection criterion for bedside tracheostomy.
  
  
  CONCLUSIONS
  These findings will aid in the development of protocols and pathways for surgical airway management in critically ill patients to maximize cost-effective, high-quality care.
