NCT01037374 | Completed DMC

• 1 other identifier: 07-0144
• Study Type: interventional
• Target: 89
• Locations: 1 country
• Sites: 1

Brief Summary

The purpose of this study is to see if our experimental preoperative airway assessment form is a better indicator of difficult airway as compared to the anesthesia record that is presently used.

Conditions

Endotracheal Intubation Risk Assessment

Keywords

risk; assessment; difficult; endotracheal; intubation

Outcome Measures

Primary Outcomes (1)

• Use of an experimental preoperative assessment form by residents will result in more complete documentation of important airway features compared to use of the current forms

  interim analysis will be assessed after 1 year

Secondary Outcomes (5)

• use of the experimental preoperative assessment form will result in greater resident recognition of patients at high risk for a difficult airway as judged independently by one of 3 senior faculty investigators.

  interim analyses will be assessed after 1 year

• the percentage of patients intubated using an awake method will be greater among residents using the new form than those using the current form

  interim analysis will be assessed after 1 year

• the percentage of patients requiring multiple intubation attempts or use of invasive airway techniques will be lower among residents using the new form.

  interim analysis will be assessed after 1 year

• spontaneous knowledge of important airway features will be more complete among residents using the new form at 18 months of training.

  interim analysis will be assessed after 1 year

• observations made during this study will allow refinement of the new form to augment the identification of patients with difficult airway.

  interim analysis will be assessed after 1 year

Interventions

Preoperative assessment form OTHER

(based on the american society of anesthesiologists)components of the form include: neck measurements; neck mobility; mallampati; wilson's test; pre-existing conditions; and predictions of difficult mask ventilation, supraglottic airway, laryngoscopy, intubation, and surgical airway.
