Effect of Mentoring on Endotracheal Tube Exchange Using a New Device

Study Overview
=================
Brief Summary
-----------------
The purpose of this pilot study is to compare the time it takes to change a breathing tube with a new device, performed by two different groups of anesthesiologists; one group will study on their own how to change the tube, while the second group will also receive expert training, before either group performs the procedure for the very first time. The Investigators predict the group who gets expert training will change the tube faster, and those investigators also need to learn how much faster, before moving to a larger study.

Detailed Description
-----------------
After informed consent is obtained, two groups of randomized anesthesiologists will receive detailed instructional materials including a brochure to introduce the new device, a videotape showing how the device is used, a detailed slide show explaining each of the steps, and a checklist of the steps to perform during the exchange (E) in simulation. The Mentored group (M) will also receive expert instruction just before the procedure, while the Control group (C) will have the same amount of time to review the steps themselves. Next, they will perform the first exchange procedure (E1) while the pair of experts observe and measure the simulated patients' apnea time. The experts will then conduct a debriefing with the M group, while the C group will debrief themselves before both groups perform the exchange a second time (E2). Both groups will then receive debriefing by the experts. The apnea times and a performance assessment will be compared between M and C to determine the effects of expert training, and will also be compared within each group from E1 to E2, to determine the effect of experience on apnea time and performance. Finally, surveys conducted after E1 and E2, and before debriefing, will determine the participants' satisfaction with the new device. Data on apnea times will be used for a statistical power analysis to determine the size of a larger group necessary to show significant differences in outcomes.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Apnea Time | Apnea time was measured in seconds from the time the ventilator was disconnected from the original endotracheal tube to the time the ventilator was connected to the new endotracheal tube immediately after procedure. | immediately after the procedure | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Performance Score | The performance score is obtained form the performance Score Sheet that includes 15 actions, 1 point is given for each completed action. The minimum score is 0, the maximum score is 15. Higher scores relate to better performance. | immediately after the procedure |
