How do you interpret this information?”
An otherwise healthy 50 year old man was admitted to the Intensive Care Unit 24 hours ago, after multi level cervical fusion. The anaesthetist noted that he was difficult to intubate and he is now being considered for extubation. The anaesthetist recorded a grade IV Cormack and Lehane view at laryngoscopy on the anaesthetic record and that intubation had been achieved with the aid of a gum elastic bougie. Pre-operatively his Mallampati score was a grade III.
The aims of the viva are to assess whether the candidate can:
formulate a plan for safe extubation
manage a difficult intubation after failed extubation
diagnose and treat bilateral tension pneumothoraces from barotrauma during resuscitation
An 18-year-old man has been brought into the Accident & Emergency Department by ambulance. He has attempted suicide by hanging. His Glasgow Coma Scale score is 5 and he is being ventilated via a laryngeal mask which was inserted at the scene by the ambulance paramedic. You have been called to provide airway management in the acute phase. Outline how you would assess this patient’s airway.
A 45-year-old policeman attending a domestic dispute was punched in the throat. He presents to ED with a severe pain in his throat and a hoarse voice. You are called to provide emergency airway assistance if required. How are you going to assess his airway?
A 30-year-old man remains intubated and ventilated following complications during the drainage of an acute dental abscess at another hospital. Great difficulty was experienced with intubation resulting in a hypoxic cardiac arrest and possible airway soiling. The airway was secured at that time by fibreoptic nasotracheal intubation. Following surgery, the decision was made to electively ventilate the patient overnight via nasal endotracheal tube. Intensive Care requests your assistance with extubation. What is your plan of management for extubation?
A 70-year-old man is having radiotherapy for carcinoma of the tongue, and has been admitted to ICU with breathing difficulties. He has mucositis and neck swelling. He is unable to lie flat and is receiving oxygen via a CPAP mask. The intensivist has asked you to secure his airway. The ear, nose and throat surgeon is reluctant to perform awake tracheostomy. The patient has a history of cardiac disease with previous myocardial infarction and coronary stenting. He is on aspirin and clopidogrel. How will you assess and manage this man’s airway?
An otherwise well 38-year-old woman presents to the Emergency Department with gradually worsening exertional stridor over several weeks. There is no stridor at rest. At nasendoscopy she is found to have a large papilloma involving the posterior laryngeal inlet. The ENT surgeon wishes to treat this with CO₂ laser therapy under general anaesthesia. The diameter of the laryngeal inlet was estimated during nasendoscopy as 6 mm. Recent hospital records indicated that there have been no previous difficulties with laryngoscopy or endotracheal intubation. The patient has never smoked and does not take any medications. Please describe your anaesthetic management plan for this patient.
A 22-year-old male with developmental delay and epilepsy sustained facial trauma after falling down several steps onto a concrete path during a seizure 3 hours ago. At a previous anaesthetic, 6 years earlier, he was documented to be a ‘Grade 3 view’ at direct laryngoscopy. He is currently in the holding bay awaiting surgical intervention for his ongoing facial bleeding. You are called urgently to the holding bay as he is having a generalised tonic clonic seizure. How are you going to manage this situation?
You are called to attend a 60-year-old man who has presented to your Emergency Department with breathing difficulty that has worsened over the last four hours. He has known carcinoma of the tongue and had been scheduled for hemiglossectomy and radical neck dissection in one week’s time. His only known past history is heavy alcohol consumption and 40 pack-years of cigarette smoking. Describe your airway management plan.
It is 1100 hours on Saturday morning and you are working in a large metropolitan hospital. You have just finished a case when you are phoned by the registrar in the high dependency unit. An 84-year-old man who underwent neck dissection for melanoma two days ago is now in respiratory distress. A large right-sided neck swelling has developed over the last two hours. His SpO2 is 97% on 15 l/minute of oxygen; his blood pressure is 140/80 mmHg and his heart rate is 95 /minute. He has a background history of atrial fibrillation and transient ischaemic attacks, for which he takes dabigatran, 110 mg twice daily, as his only medication. Dabigatran was ceased two days preoperatively and recommenced orally three hours ago. He was bridged with enoxaparin; the last dose of enoxaparin 1.5 mg/kg was 12 hours ago. You have two minutes to consider the case as you proceed to the high dependency unit. What further key information do you want to obtain once you get to the bedside?
“You are the on-call consultant anaesthetist in a tertiary hospital. You are called by your advanced anaesthetic trainee to the Emergency Department to assist with the airway management of a 56-year-old woman. She has a three-month history of progressive dyspnoea, with acute deterioration in the past 12 hours requiring ambulance transfer to hospital. A diagnosis of asthma was recently made, but she has had no significant response to medical treatment. She has a known history of a previous thyroid tumour. There are no known allergies, and her only medication is salbutamol prn.
The Emergency Department registrar has noted a large thyroid mass on examination. When you arrive, it is apparent that the patient is tiring and clearly distressed. Her chest X-ray is shown here. Outline your assessment of this patient’s dyspnoea.”
“Your junior anaesthetic registrar calls you at home at midnight from the Emergency Department. He has been requested to assist with the intubation of a 72-year-old woman who has presented with severe epistaxis. Her medical history includes mechanical aortic valve replacement, hypertension, and past
cerebrovascular accident.
Her current medications are:
Warfarin 5 mg daily
Metoprolol 12.5 mg bd
Perindopril 4 mg bd
Amlodipine 10 mg daily
Your registrar informs you that preparations are underway to intubate this patient. How will you respond to his phone call?”
You are in the pre-anaesthetic assessment clinic. A 62-year-old man is scheduled for microlaryngoscopy and excision of vocal cord lesions. The patient has been referred to the clinic because of a history of difficult intubation during elective carotid endarterectomy under general anaesthesia five years ago. The surgery is planned for next week. A picture of the patient is shown here. What are the key issues in his airway assessment?
A 35-year old man is booked on the emergency theatre list for drainage of a submandibular abscess. The patient is homeless, a known intravenous drug user and seems unwell. You meet him in the holding bay area outside the operating theatre suite. What are the main issues that worry you?
You are today’s Team Leader of the hospital Medical Emergency Response Team. You have been called to assess a 33-year-old woman in the surgical ward, who had a mandibular molar abscess drained 36 hours ago. She is 160 kg and 170 cm tall. She is confused and refusing any oxygen therapy. Pulse oximetry erratically reads 84% and a heart rate of 110 bpm. How will you respond to this situation?
There has been a brawl at a nearby prison. One of the inmates is transferred to your hospital for treatment. He is a 24-year-old man with a mandibular fracture, and a background history of hepatitis C, smoking and intravenous drug use. You are seeing him in the waiting area immediately before surgery. What features on examination of this patient would suggest a difficult airway?
You are the consultant on call at a tertiary referral hospital on a Sunday afternoon. You receive a call from the intensive care unit registrar asking for assistance in managing the airway of one of their patients. The patient is a 20-year-old apprentice chef who suffered facial and neck burns this morning after a deep fryer caught fire at work. She was intubated on admission, and this afternoon the pilot tube on her endotracheal tube was cut whilst dressings were being changed. What is your initial response?
“You are the duty consultant anaesthetist at a tertiary hospital. You are called to come immediately to the intensive care unit (ICU) to help other medical staff struggling with the airway management of a patient with a tracheostomy.
On arrival you see:
* the ICU consultant attempting to insert a laryngeal mask airway (LMA)
* an ear, nose and throat (ENT) surgical registrar attempting to replace the tracheostomy tube
* oxygen saturation SpO2 86%
* heart rate 122 beats per minute
* blood pressure 195 / 115 mmHg
The ICU consultant tells you this is a 55-year-old man weighing 165kg who has community- acquired pneumonia. The patient had a surgical tracheostomy three days ago. The tracheostomy tube has now become dislodged while turning the patient. What are your priorities?”
“A 56-year-old man with supraglottitis required a tracheostomy under local anaesthetic on presentation to hospital three days ago. Since that time, he has been in the Intensive Care Unit receiving antibiotics and dexamethasone. Overnight the anaesthetic registrar was asked to see the man regarding some minor neck swelling. This was managed conservatively. This morning the man has been restless and has completely dislodged his tracheostomy. You are called as the duty anaesthetist to assist the junior ICU registrar. As you arrive into the ICU bay this is how the patient appears: He is moving around the bed trying to get himself comfortable. His observations as they appear on the
ICU monitor are:
RR 26
SaO2 90% on Oxygen 10l/min
BP 100/52 mmHg
HR 125 bpm
Picture of significant subcutaneous emphysema
Outline your initial assessment and urgent management”
You are called to the emergency room of a level 1 trauma centre as part of a trauma team call. A convoy of 15 motorcyclists was struck by a truck. There was a fire at the scene and 2 people have died on site. Your centre is receiving 3 patients. You are assigned as the airway doctor for 1 of the patients arriving by road ambulance. Additional information provided by paramedics: He is a 48-year-old male, weight 123 kg and height around 174 cm. He was wearing an open-faced helmet, removed at the scene. He has a partially singed beard with bruising and swelling of his midface. He is vocalising with no obvious stridor or hoarseness. What are your specific airway concerns?
As the duty anaesthetist receiving emergency bookings, you take a phone call from the ENT registrar, who is in the Emergency Department with a 26-year-old man requiring urgent surgical drainage of a suspected peritonsillar abscess. The registrar reports that the patient is very distressed, refuses to lie flat and cannot open his mouth more than 1.5cm. Outline your initial management, assessment and concerns for anaesthesia.
“You review a 67-year-old man in the Preadmission Clinic (PAC) for a left hemihepatectomy via
