title: Preemptive vessel dilator cricothyrotomy aids in the management of upper airway obstruction.
abstract: OBJECTIVE
  Our objective was to demonstrate that preemptive vessel dilator cricothyrotomy may be useful when managing the patient with airway obstruction.
  
  
  METHODS
  An Institutional Review Board approved retrospective study was undertaken in 88 patients for whom this technique was selected. The anesthesiologists and surgeons identified as authors were directly involved in the care of these patients. All vessel dilator cricothyrotomies were performed in the operating rooms of University Hospital, UAB, Medical Center. The patients selected for this airway management technique were afflicted with some type of supraglottic lesion, usually squamous cell carcinoma, which was obstructing their airways to an extent that complete airway obstruction during induction of anesthesia was a significant possibility. Prior to induction of anesthesia, the vessel dilator was inserted into the tracheal lumen through the cricothyroid membrane as described. Oxygenation was maintained with jet ventilation from a Sanders jetting device. Age, sex, weight, initial and lowest O(2) saturation, first recorded ETCO(2), blood pressure and duration of jet ventilation were recorded.
  
  
  RESULTS
  The airways were successfully managed in all 88 patients with this technique. There were no deaths, and no postoperative hypoxic sequelae; also complications were minor.
  
  
  CONCLUSIONS
  Vessel dilator cricothyrotomy as a preemptive procedure in the management of patients with significant supraglottic airway obstruction may be a useful addition to the anesthesiologists' armamentarium of airway management devices.
