Team Training: Unanticipated Difficult Airway 4
2. Description of Curriculum
Course Overview:
This course is designed to teach learner(s) to recognize and manage an airway emergency which occurs in the setting of a failed spinal anesthetic.
The patient experiences pain after the surgery has started due to the tourniquet and, as result of injudicious sedation, becomes apnoeic and starts to desaturate. The patient simulator is placed in a state where it is impossible to be ventilated or intubated. The resident should recognize the seriousness of the situation and call for help. The ‘attending anesthesiologist’ should proceed according to American Society of Anesthesiologists (ASA) unanticipated difficult intubation guidelines, and eventually perform a cricothyroidotomy.
The secondary goal will be for the more junior resident (R2) to be able to perform intrathecal anesthesia. This includes reviewing the patient history and physical examination, especially an airway examination and discussing informed consent regarding the potential benefits and risks of a spinal anesthetic including the potential for a failed regional which may require general anesthesia. They should also be able to set up and perform the procedure using the appropriate monitoring.
Educational Rationale on How the Course Generalizes to Real-Life Circumstances: A “cannot intubate and cannot ventilate” event is a rare but serious situation which can arise due to the administration of anesthetic drugs. An anesthesiologist should be able to do a thorough preoperative airway examination in order to assess the likelihood of both difficult ventilation & difficult intubation. If the situation does arise unexpectedly however, the learner should be able to deal with it appropriately.
The goal of this course is to provide the learner with an opportunity to manage a life threatening airway emergency which plays out in real time, where the correct steps need to be taken in a limited period of time. Key elements include: 1) evaluating the preoperative airway, even though the procedure is performed under a regional anesthetic (note that the difficult airway will be unrecognized), 2) recognizing the need to call for assistance early in an event, 3) being able to use various alternative techniques for airway management, and 4) optimizing resource management skills.
Duration of Training Session: 2 hours.
Frequency of Course: 6 to 10 times per year.
Number of Trainees per Session: 3-5

5. Goals and Objectives
Goal 2: Management of conscious sedationThe learner will be able to provide sedation in a safe and professional manner. (ACGME Competencies: Medical Knowledge1, Patient Care2, Interpersonal and Communication Skills3, Professionalism4, System-based Practice5)
Objective 2a- Appropriate sedation [1,2,3,4,5]
The learner will be expected to provide sedation with continuous assessment of the effects of the sedative medications on the level of consciousness and on cardiac and respiratory function.They should be prepared to convert to general anesthesia if required.
Objective 2b- Recognition of over sedation [1,2,3,4,5]
The learner should anticipate that using more sedatives and intravenous analgesia could result in progressing beyond “conscious sedation”. The patient’s level of consciousness and respiratory rate should be continually re-assessed. They should recognize when the patient becomes unresponsive to voice and eventually physical stimulation. Airway support should be started when the patient becomes apneic.

5. Goals and Objectives
Goal 5: ExtubationAfter stabilizing the patient with a surgical airway, the learner should present a plan for further management of the patient. The learner should be able to discuss what they would do postoperatively when the patient is ready to be extubated. (ACGME Competencies: Medical Knowledge1, Patient Care2, Interpersonal and Communication Skills3, System-based Practice5, Practice-based Learning6)
Objective 5a – Criteria for extubation [1,5]
The learner will describe the process of assessment to ensure a successful extubation.
Objective 5b – Management of the extubation [1,2,3]
The learner should explain how he/she would safely extubate the patient including steps that would facilitate re-intubation if the patient is not able to maintain an airway or adequate ventilation.
Goal 6: Team Training and Communication SkillsThe learner will become skilled in leadership and the management of operating personnel including nurses and anesthesia technicians. (Competencies: Interpersonal and Communication Skills3, Professionalism4, System-based Practice5, Practice-based Learning6)
Objective 6a – Team Training and Communication SkillsGiven a full-scale high-fidelity simulation using a human patient simulator in which the learners are faced with an inability to maintain or secure an airway, the learner will direct available resources to manage the crisis situation prioritizing patient safety.
Goal 7: Record KeepingThe learner should be able to demonstrate the importance of accurate recording keeping during an intra-operative critical event (Competencies: Patient Care2, Professionalism4, System-based Practice5)
Objective 7a– Record Keeping Given a full-scale high-fidelity simulation using a human patient simulator in which they have to deal with an airway emergency, the learner should be able to accurately document records during the event.
1. Ensure simulation room is correctly prepared Ensure the room is set up exactly the same as the hospital setting that
the learners are used to. All routinely used equipment should be in an expected location.
Additional items, such as the code cart or difficult airway cart, should not be visible. If needed, the participants should specifically request these items.
Standard monitoring may be attached prior to the simulation session in order to save time. With junior residents, monitoring may be left unconnected to ensure proper knowledge of appropriate monitoring required for spinal anesthesia.
2. Briefing prior to simulation session Discuss capabilities of simulator: where pulses can be felt, where to
listen for breath sounds. The instructor should ensure that learners can use the monitoring
correctly (For instance, the learner should be able to start the automatic blood pressure cuff and set it to repeat the blood pressure measurement at the appropriate interval).
The instructor should discuss resources available (i.e. asking anesthesia technician for equipment, location of telephone to call for help, etc.).
The instructor should discuss any deviations from the situation they would expect in the operating room. For instance: the inhalation agent vaporizer does not have an anesthetic agent present. What is set on the vaporizer dial will reflect the depth of anesthesia.
The learner should not assume that there is a problem with the simulator if something unexpected happens. They should act as they would if this were a real patient. Everything happens in real time (i.e. a chest X-ray will not be available, instantaneously).
The instructor will establish a safe environment. Emphasizing the focus of the course is to improve their ability to deal with a crisis situation.
Discuss principles of team management, including what is expected of the team leader and team members.
Instruct learners to call out drug names and dosages, so that this can be entered in the simulation.
Trainees should sign a consent form, agreeing not to discuss performance of team members outside of the simulation environment.
We also mention that the session is recorded on video as an aid during the debriefing. We ask them to sign a consent for archiving the video. If any one of the participants is not agreeable for the video to be archived, it is destroyed at the end of the day.
Team Training: Unanticipated Difficult Airway 11
6. Instructor’s Notes
3. Additional notes during session The “patient” should insist on having a spinal, citing a friend (no familial
relationship) has had complications related to general anesthesia. The spinal simulator is brought into the room when the learners are
ready to proceed with a spinal. The simulator should be in clear view of the video camera used to record the session.
We have found that some learners will persist in doing oral intubation to the extent of breaking teeth on the manikin. We have changed to using rubber teeth. The “surgeon” should watch for persistent attempts at intubation, and point out how repeated intubation attempts may traumatize the airway, making subsequent attempts more difficult.
The “patient” should respond to actions by the anesthetic team (i.e. “The mask makes me feel claustrophobic” when a mask is placed on his face, or “Ouch!” when the spinal is done). This will add to the realism of the scenario and consequently, the degree of engagement by learners.
When the learners call for a surgical airway, we bring in a cricothyroidotomy simulator. Once the surgical airway has been established, the vital signs improve and the simulation is stopped.
4. Debriefing Please refer to section B for detailed debriefing notes. Participants are accompanied to the debriefing room. A video recording
is available to review key parts of the simulation. Key points for the debriefing:
Facilitate the discussion rather than giving a lecture, Learners should discuss why they chose certain courses of action
and discuss the consequences. Ask what they would do the same or differently if they did the same scenario again,
Engage everyone in the discussion particularly quiet team members. Key topics for discussion should include:
Sedation in a patient with a full stomach, Spinal anesthesia, Doing a rapid sequence induction, Management of a "Cannot intubate, cannot ventilate" emergency.
Briefly review the ASA guidelines for managing a difficult airway. Every participant receives a copy of the current guidelines.

Team Training: Unanticipated Difficult Airway 13
7. Common Errors & Prevention Strategies
Common errors observed in trainees and strategies for helping address the errors include:
1. Failure to anticipate a potential full stomach.Review factors which can delay gastric emptying (i.e., pain drugs) Discuss the potentially catastrophic consequences of dealing with a difficult airway in the setting of aspiration.
2. Persistence of sedation when the regional is not adequate.Review the potential risks for apnea, airway obstruction & aspiration, when sedation is used to cover pain from surgery or the tourniquet, in a situation where the spinal anesthesia is clearly not adequate.
3. Fixation error: failure to advance to a different approach if one method of ventilation is not effective.The instructor will discuss the potential for causing trauma, as well as the consequences of delaying definitive management of hypoxia. Learners should be able to explain reasons why a particular technique was not successful, and then try a different approach, circumventing the problem.
4. Failure to call for help earlyThe instructor should emphasize the importance of calling for help before the problem becomes life threatening.
5. Inefficient communication & teamworka. Lack of leadership
b. Unclear or ambiguous messages
The instructor should discuss the importance of clear communication and leadership during the management of an emergent airway management scenario.
General strategies to solve the problems Increase knowledge base through assigned reading and lectures.
Keep debriefing focused to re-evaluate critical thinking and structure planning of actions.
Utilize areas for improvement as teaching points.
Promote regular simulation training as an opportunity to correct previous mistakes.

9. Skill Training
Participants:
Doctor #1: Attending anesthesiologist (this is usually the most senior resident – R4)
Doctor #2: Anesthesia Resident (Junior resident)Doctor #3: Available attending (This is generally the R3 resident)
Doctor #4 / Nurse #1: Circulating nurseInstructor 1: Attending anesthesiologistInstructor 2: Surgeon
Briefings:
1. The course will include a brief introduction to the simulator. Learners are asked to not disclose the details of the scenario to other residents, and also to refrain from discussing each other’s performance outside of the simulation environment.
2. Review capabilities of simulator: Breath sounds - where to listen, make them listen Heart sounds Blood pressure - can take manual BP, how to start NIBP Pulse - where to feel Voice Emphasize that when a drug is administered, the person giving it should
clearly state the name & dose of the drug. Do not assume that something is wrong with the simulator if a problem occurs.
3. Review equipment in room: Set the scene – the patient has been pre-assessed and is in the operating
room. Emphasize everything that occurs is actually happening. Address any questions?
4. Doctor #2 will be asked to wait in the lounge.
6. The patient should be anxious and complain about pain as the learners enter the room. The patient should request more sedation.
7. The surgeon should prep & drape the field after the spinal block is established, and then proceed with mock surgery. He or she will be unable to perform surgical airway if requested but may be of assistance for any other tasks.
Team Training: Unanticipated Difficult Airway 16
9. Skill Training-Continued
The Case:
Act #1: Simulation room: Handover
Instructor #1 will be the attending anesthesiologist originally assigned to anesthetize the patient. He/she has already pre-assessed the patient and has discussed performing a spinal anesthetic with the patient.
Instructor #1 will hand over care of the patient to all participants, except Doctor #2. Doctor #1 (“Attending”) & Doctor 2 (“Resident”) will need to introduce themselves to the patient and confirm the pre-assessment by completing a focused history & examination including airway assessment. The two will need to discuss how they would go about performing spinal anesthesia including IV access, monitoring equipment, emergency drugs & emergency equipment, etc.
Act #2: Simulation room: Spinal
Rhythm: sinusHR: 83 bpmBP: 150/90Sat: 96%RR: 20/min
This will be done using the spinal simulator. The learner should describe the steps he/she will complete, as if this were a real patient. He/she should set up a spinal tray and then perform a spinal. The learner should be able to describe pertinent anatomy.(If the residents are junior, the instructor would go through the correct procedure for setting up the tray.)
The trainee will identify: What drugs Combinations of drugs Dosage
Team Training: Unanticipated Difficult Airway 17
Act #3: Sedation
Rhythm: sinus O2 Sat98%HR: 60 bpm RR 18/minBP: 110/60 ETCO2 21mmHg (Connected to O2 mask)
IV line in situECG, Pulse oximeter & NIBP in situO2 Mask on face with ETCO2 sample line attached
The “Patient”
Awake, anxious, requesting sedation (Is this going to hurt, what is happening, what are you giving me etc.)
Block level is to T12, unable to move legs.
The surgeon places a tourniquet, preps & drapes field & (eventually) starts operating.
After a period the patient starts complaining of pain in his leg related to the tourniquet and requests more sedation until he becomes unresponsive and apnoeic.
The events should be the same if the resident does a rapid sequence intubation.
Trigger for Act 4 is sedation / rapid sequence inductionArbitrary cutoff: midazolam > 5mg, fentanyl > 200mcg, propofol > 100mg or propofol infusion

Debriefing Questions. General points:The Basic Assumption for the debriefing is:We believe that everyone participating in the simulation scenario is intelligent, well-trained, cares about doing their best, and wants to improve.
Critique the performance, not the individual Ask open ended questions – avoid yes/no questions
Framework for debriefing:A. Reactions
Clear the air and set the stage for discussion Facts
1) What happened? Participants often want to know "the answer" Stick to the facts
2) How did you feel about that? Accept expressions of feelings
- Acknowledge is not the same as agree - Try to mirror feelings rather then evaluate them - Don't tell participants "that's OK" when it may not be
Give perspective if participant feelings are hurt. e.g.:- I've seen this a dozen times and that happens nearly every time ... or- I've made the same mistake ... or- We all make mistakes and this is a good place to learn from them or ...- Remind them of the Basic Assumption and say that we’ll work together
to figure out what happened ... or ...
B. UnderstandingRemember to use Advocacy-Inquiry: be curious!
Exploring Applying Generalizing
1) Exploring What were you thinking at the time? It looked to me like …..
(Use this to discuss some error you observed and would like to find out why the student chose a particular course of action)
How do you account for that? Why did that happen? What led to it? What next?
2) Applying What drug or procedure or behavior might be best? Have you ever done this clinically? How might this be reflected in your clinical practice?
3) Generalizing Have you ever seen anything similar to this in your practice? Are there analogies to the clinical world? What can be done in analogous situations?
Appendix B: Debriefing Questions
Team Training: Unanticipated Difficult Airway 25
C. Summary Review what was learned and ensure the single scenario is put into a larger context.1) Relate this experience to higher level principles, e.g., principles of
teamwork, circulation and respiration, patient safety, etc. 2) What did you do well? 3) What would you do differently?
Specific crew resource management topics to discuss using this template:
1. Team leader’s performance: Was a team leader clearly identified? Were team members assigned to do specific tasks assigned
appropriately? Did he/she maintain awareness of the big picture? i.e. not
sidetracked Did the most life threatening issues get dealt with first?
A B C Did he/she allow team members to participate in the decision
making process? Were there any communication problems? i.e. not addressing
specific person, no parroting, miscommunication Did he/she use other resources appropriately i.e. non anesthesia
personnel?2. Team members:
Did he/she clearly communicate critical information to the team leader & other team members?
Did he/she request assistance if unable to complete task/during task overload?
Good communication: closed loop communication/parrot back, clarify instructions, verbalize activities
3. Group performance: Was everyone involved in the crises? Were there any fixation errors? Were there any conflicts? If so, was it resolved? Did the team address new emergent events effectively? What communication problems did we see?
- Get person’s attention- Make eye contact- Use names if possible- Parrot requests and responses- Use cross-checks and ‘call-outs’
Handover:- S – Situation:
I need you NOW for an airway emergency- B – Background:
55yr old male; failed spinal for ankle surgery; rapid sequence induction
- A – Assessment:can’t intubate can’t ventilate
- R – Recommendationneed help with airway management
Appendix B: Debriefing Questions (cont.)
Team Training: Unanticipated Difficult Airway 26
Specific clinical management topics (i.e. issues from checklist which were missed):
1. Any issues doing spinal?2. Escalating sedation requirements3. Option for dealing with a failed regional technique4. Was a rapid sequence induction done due to full stomach?5. Discuss contraindications for a rapid sequence induction such as a known
difficult airway. (In this scenarion, there is nothing to suggest a difficult airway.)6. Any deviations from the difficult airway algorithm?7. Was someone assigned to record events during the crises? This person can
watch for repeated intubation attempts. Attempts should not last longer than 30 seconds and the recorder can help by notifying the anesthesiologist when the intubation time exceeds 30 seconds.The recorder is particularly useful in this scenario however it is often forgotten even it there is suffient personnel available.
8. Were there any fixation errors i.e. persisting with intubation / placing LMA?9. Was a surgical airway established in a timely fashion?
Additional topics:
1. What would your further management of the patient have been? i.e. talk to family, ICU care, extubation, etc.
2. Did it feel real? How can we improve this scenario?
3. Review importance of accurate record keeping, review the record – lapses in vital signs, drugs administered.
